16th century

• Henry VII becomes king (1485–1509), founding the Tudor dynasty and ending the long civil war called "Wars of the Roses". His foreign policy involves an alliance with Spain, cemented by the marriage of his son Arthur, Prince of Wales to the Spanish princess Catherine of Aragon. However, after 5 months, Arthur dies at the age of 15. Henry VII reverses the Plantagenet policy of acquiring more French territory; he generally pursues a more defensive, Anglo-centric policy

• 1489–91: England sends three expensive military expeditions to keep Brittany out of French control, but fails.
• 1502: Treaty of "perpetual peace" signed with Scotland. The marriage of King James IV of Scotland to Margaret Tudor will eventually lead to the Stuart succession to the English throne.

• 1553–58: Mary I is queen; she promotes Catholicism and an alliance with Catholic Spain
• 1554: Mary I marries Prince Philip of Spain, the king of Spain (1556–98). "The Spanish marriage" was unpopular even though Philip was to have little or no power. However he pushes Mary into alliance with Spain in a war with France that resulted in the loss of Calais in 1558
• 1558–1603: Elizabeth I as Queen; Sir William Cecil (baron Burleigh, 1571) serves as chief advisor; they avoid European wars. Her spymaster Sir Francis Walsingham thwarts numerous plots supported by Spain or France to assassinate the Queen. The long-term English goal becomes a united and Protestant British Isles, through conquest of Ireland and alliance with Scotland. Defence is the mission of a strengthened Royal Navy.
• 1573: Convention of Nymegen a treaty with Spain promising to end support for raids on Spanish shipping by English privateers such as Drake and Hawkins.

• 1585–1604: Anglo-Spanish War (1585–1604) was an undeclared intermittent naval conflict; English strategy focused on raids on ports such as Cadiz, and seizure of Spanish merchant ships because it was much cheaper than land forces—using privateers ("Sea Dogs") who turned a large profit when they captured prizes—let the naval warfare pay for itself.
• 1588: Massive Spanish invasion thwarted by destruction of Spanish Armada; it is celebrated for centuries as a decisive defeat for England's Catholic enemy.

• 1613–20: Netherlands becomes England's major rival in trade, fishing, and whaling. The Dutch form alliances with Sweden and the Hanseatic League; England counters with an alliance with Denmark
• 1610s: English involvement with Russia; strengthens the Muscovy Company, which has a monopoly on trade with Russia. In 1613 it obtains a monopoly on whaling in Spitsbergen. A Russian embassy comes to London in 1613.
• 1613: The English captain John Saris arrives at Hirado, Japan, with the intent of establishing a trading factory. He met with Tokugawa Ieyasu. However, during the ten-year activity of the company between 1613 and 1623, only four English ships brought cargoes directly from London to Japan.
• 1623: The Amboyna massacre occurs in Japan. England closes its commercial base at Hirado. The relationship ends for more than two centuries.

• 1654–60: Anglo-Spanish War (1654–60)
• 1657: Alliance with France signed against Spain.
• 1661: King Louis XIV of France begins his personal reign, taking control of the state. Louis as the leader of the most powerful nation in western Europe begins a policy of aggressively asserting French interests and expanding the borders of France. Until his death in 1715, France's hegemonic aspirations are the principle driving drive in diplomacy in western Europe.
• 1665–67: Second Anglo-Dutch War.
• 1665: Charles II of Spain begins his reign. The last of the Spanish Habsburgs. As Carlos is childless with no Spanish relatives and as he is very sickly, his expected death raises the highly controversial issue of succession to the Spanish throne. The main candidates for the Spanish succession are the French Bourbons and the Austrian Habsburgs.
• 1667: War of Devolution. France attacks Spain and occupies much of the Spanish Netherlands and the Franche-Comté. The prospect that France might annexe the entire Spanish Netherlands is viewed as a threat in London.
• 1667: Treaty of Breda ends of the Dutch war. It is a major turning point after which mercantilism ceased to dominate Anglo-Dutch relations.
• 1668: Triple Alliance of England, Sweden and the United Provinces formed to oppose France. Spain is defeated, but the threat that the Triple Alliance might intervene on Spain's side forces the French to make peace. Louis annexes less Spanish territory than what he planned on. The French decide that the Dutch will be their next target, and accordingly Louis seeks to break up the Triple Alliance by bidding for English and Swedish friendship.
• 1670: Treaty of Dover. Secret Anglo-French alliance formed. In exchange for French subsidies and a promise to send an army to England should another civil war break out between king and Parliament, Charles II agrees to convert to Catholicism and to fight with France against the Dutch.

• 1673: Revelation of the pro-Catholic Secret Treaty of Dover causes public backlash against the war and the Crown.
• 1688–89: William of Orange invades from the Netherlands as King James II flees; becomes William III; called the Glorious Revolution Louis continues to recognise the deposed James II/VII, who takes refuge in France and is promoted by France as the legitimate king of England, a policy known as Jacobitism. French support was a major factor in British diplomacy until the mid-18th century. William allows James and his family to escape after being captured as the threat of a Jacobite restoration supported by France forces gives those who supported the Glorious Revolution a vested interest in ensuring that England is not defeated by France, and James is restored. Parliament accordingly votes for all the war taxes William requests. From William's viewpoint, James is more useful as king in exile in France than as a prisoner in the Tower of London.
• 12 May 1689: Reflecting the changed foreign policy orientation caused by the Glorious Revolution, William has England join the anti-French League of Augsburg and declare war on France (as a stadtholder of the United Provinces, William had already declared war on France on 26 November 1688.).
• 1689–97: War of the Grand Alliance with France; also called "Nine Years War" or "War of the League of Augsburg" or " King William's War"
• 1697–98: During the Grand Embassy of Peter I the Russian tsar visited England for three months; improved relations and learned the best new technology especially regarding ships and navigation.

The largest portion of the Spanish realms are to go to Josef Ferdinand of Bavaria. The treaty is undermined when Josef Ferdinand dies in 1699.

1700–1789

• 25 March 1700: Another partition treaty signed between France, England and the United Provinces concerning the Spanish succession with the Bourbons receiving Naples, Sicily, Milan and the Spanish fortresses in Tuscany and the rest of the Spanish realms going to the Austrian Habsburgs. The proposed partition breaks down when the Holy Roman Emperor Leopold I insists that the entire Spanish empire go to his son Archduke Karl.
• 1 November 1700: Carlos II of Spain dies, leaves the entire Spanish succession to Duke Philippe of Anjou, the second son of the Dauphin who becomes King Felipe V of Spain. King Louis XIV of France issues letters patent explicitly stating that Philip is in the line of succession to the French throne, creates the possibility of France and Spain uniting to become a Catholic super-state that would dominate Europe. Additionally, Louis takes the opportunity to remind the world that he recognizes the Catholic the Old Pretender as King James III of England/James VIII of Scotland. Louis's actions which are seen as very threatening to England and all but guarantee a war.
• 1701–15: War of the Spanish Succession against France and Spain, in "Grand Alliance" with Austria, Prussia and the Dutch Republic. Britain fights in support of the Habsburg Archduke Karl of Austria's claim to the Spanish throne.
• 15 May 1702: War declared against France.

• 1708: Louis XIV sues for peace. The French agree to the Allied demand that the Archduke Karl become King of Spain, but the talks break down over the Allied demand that Louis send an army to Spain to depose his grandson Philip.
• 12 June 1709: Louis XIV says he was willing to concede to the Allied demands over the Spanish succession, but rejected the demand that he send an army to Spain to depose as an insult to French national honour. French win the moral high ground as many people in France, Britain and elsewhere see the demand that Louis depose Philip to be outrageous. New French commander Marshal Claude Louis Hector de Villars appointed to oppose Marlborough, proves to be the ablest French general of the war.
• 11 September 1709: Bloody Battle of Malplaquet. Marlborough victorious over Villars, but Malplaquet is a Pyrrhic victory with the British losing twice what the French suffered. Public opinion in Britain turns against the war after Malplaquet. Vigorous attacks by the Tory opposition on the Whig government for the war, its support of "Butcher Marlborough" and widespread corruption in regards to war contracts.
• 2 October–16 November 1710: General election results in a landslide victory for the Tories on a peace platform.
• 17 April 1711: Holy Roman Emperor Josef I dies, and his younger brother the Archduke Karl is elected his successor. Queen Anne and her ministers see no point to continuing the war as allowing Karl to become King of Spain would create a Habsburg super-state which would be just as much a potential danger as a Bourbon super-state.

• 1739–42: War of Jenkins' Ear begins with Spain over smuggling and trade. Public opinion demanded it over Walpole's opposition; he fell from power. The war was inconclusive and expensive; it hurt legitimate trade. It merged into the War of the Austrian Succession in 1740.

1789–1815

• 1789–1815: The French Revolution polarized British political opinion in the 1790s, with conservatives outraged at killing of the king, the expulsion of the nobles, and the Reign of Terror. Britain was at war against France almost continuously from 1793 until the final defeat of Napoleon in 1815. Its strategy was to mobilize and fund the coalition against France. William Pitt the Younger was the dominant leader until his death in 1806. At home, conservatives castigated every radical opinion as "Jacobin" (in reference to the leaders of the Terror), warning that radicalism threatened an upheaval of British society.
• 1791–92: Government rejects intervention in French Revolution. Reasons are based on realism not ideology and are to avoid French attacks on the Austrian Netherlands; to not worsen the fragile status of King Louis XVI; and to prevent formation of a strong Continental league.

1815–1860

• 1814–22: Castlereagh as Secretary of State for Foreign Affairs (foreign minister) works with the Congress of Vienna to provide a peace in Europe consistent with the conservative mood of the day. His Congress system sees the main powers meeting every two years or so to collectively manage European affairs. It resolves the Polish-Saxon crisis at Vienna and the question of Greek independence at Laibach. The following ten years saw five European Congresses where disputes were resolved with a diminishing degree of effectiveness. Finally, by 1822, the whole system had collapsed. During this period, Russia emerges as Britain's main enemy, mostly because of tensions associated with the Eastern Question. Anglo-Russian rivalry only ends in the early 20th century.
• 1817: Third Anglo-Maratha War (1817–1818) – India

• 1822–27: George Canning in charge of foreign policy, avoids co-operation with European powers; supports the United States (Monroe Doctrine) to preserve newly independent Latin American states; goal is to prevent French influence and allow British merchants access to the opening markets. Temperley summarizes Canning's policies, which formed the basis of British foreign policy for decades:

non-intervention; no European police system; every nation for itself, and God for us all; balance of power; respect for facts, not for abstract theories; respect for treaty rights, but caution in extending them … a republic is as good a member of the comity of nations as a monarch. 'England not Europe.' 'Our foreign policy cannot be conducted against the will of the nation.' 'Europe's domain extends to the shores of the Atlantic, England's begins there.'

• 1821–32: Britain supports Greece in the Greek War of Independence from the Ottoman Empire; the 1832 Treaty of Constantinople is ratified at the London Conference of 1832.

• 1824: First Anglo-Burmese War (1824–1826) in Burma
• 1830–65: Lord Palmerston dominates British foreign policy; his goal was to keep Britain dominant by maintaining the balance of power in Europe; he tried to keep autocratic nations like Russia in check; he supported liberal regimes because they led to greater stability in the international system.
• 1833: Slavery Abolition Act 1833 frees slaves in Empire; the owners (who mostly reside in Britain) are paid £20 million.

• 1852: Second Burmese war; British Burma annexed; the remainder of Burma is annexed after the Third Anglo-Burmese War in 1885.
• 1853–56: Crimean War with Russia. British policy, in league with France, is to protect the decaying Ottoman Empire from Russian advances. The war itself is largely fought on the Crimean peninsula in southern Russia, and is mishandled by both sides.

• 1878: Widespread "jingoism" celebrates sending a British fleet into Turkish waters to counter the advance of Russia.
• 1878: Treaty of Berlin gives Britain possession of Cyprus. Britain leases Cyprus from Turkey in order to block possible Russian expansion. In 1914 Britain annexed Cyprus and made it a crown colony in 1927. Disraeli boasts that he secured "Peace with honour" as well as Cyprus.
• 1879: Egypt goes bankrupt. Loss of Egyptian financial independence to a consortium of European bankers. Evelyn Baring sent to reorganise the Egyptian government in order that Egypt could pay off its debts.
• 1879: Anglo-Zulu War. British forward policy in South Africa aiming at complete control of the country as Britain wishes to maintain control over the alternative Cape route in case the Suez Canal should not be available.
• 1880: Foreign policy is a major issue in the British general election, helping Liberals under Gladstone to defeat Disraeli's Conservative Party by a landslide.
• 1880–81: First Boer War; Britain defeated by the South African Republic of the Afrikaners
• 1880s: Gladstone calls for a "Concert of Europe" – a peaceful European order that overcomes traditional rivalries by emphasising co-operation over conflict, mutual trust over suspicion. He proposes that the rule of law should supplant the reign of force and beggar-thy-neighbor policies. However, he was outmaneuvered by Bismarck's system of "realpolitik" using manipulated alliances and antagonisms.
• 1881: Pretoria Convention ends war with the Transvaal and Orange Free State. Henceforward, the Boer republics are independent with a vague British claim of suzerainty. Source of much future tension as the Boer republics see themselves as completely independent states while Britain does not.
• 1882: Uprising in Egypt led by Ahmed Orabi against the foreign control of the government. British take control of Egypt after a war (although it remains nominally part of Ottoman Empire).
• 1883: United Kingdom–Korea Treaty of 1883 is signed.
• 1883–1907: Lord Cromer rules Egypt as consul general
• 1885: The Panjdeh incident causes a war scare with Russia.
• 1885–1902: Historians agree that Lord Salisbury as foreign minister and prime minister was a strong and effective leader in foreign affairs. He had a superb grasp of the issues, and proved:

a patient, pragmatic practitioner, with a keen understanding of Britain's historic interests....He oversaw the partition of Africa, the emergence of Germany and the United States as imperial powers, and the transfer of British attention from the Dardanelles to Suez without provoking a serious confrontation of the great powers.

• 1886: Witwatersrand Gold Rush. Gold is discovered in the Transvaal. The new wealth of the South African Republic threatens to undermine the assumptions behind the Pretoria convention as it was felt that the two Boer republics were too small and weak to threaten British rule over the Cape Colony and Natal, and thus British control over the Cape route to India. Now with gold being mined in the Witwatersrand, the South African Republic uses its new wealth to go on an arms-buying spree in Europe, which potentially could threaten the British position in South Africa. Renewed British push to bring all of southern Africa under its control.
• 1887: To protect the Suez Canal and the sea lanes to India and Asia, Prime Minister Salisbury signs the Mediterranean Agreements (March and December 1887) with Italy and Austria. This aligns Britain indirectly with Germany and the Triple Alliance.
• 1889: Salisbury increases he dominance of the Royal navy through the Naval Defence Act 1889, with an extra £20 million for ten new battleships, thirty-eight new cruisers, eighteen new torpedo boats and four new fast gunboats.
• 1890–96: Britain suffers a series of diplomatic reverses, including the abandonment of the Congo treaty with Belgium; the French conquest of Madagascar; the collaboration of France, Russia and Germany in the Far East; the Venezuela crisis with United States; the Armenian massacres in the Ottoman Empire; the emerging alliance between France and Russia; and the debacle of the Jameson Raid; debates focus on Britain's lack of allies.
• 1890–1902: Salisbury promotes a policy of Splendid isolation with no formal allies.
• 1890: The South African Republic passes a law that disenfranchised most of the uitlanders as foreign, mostly British workers in the Transvaal's gold fields are known. The uitlander issue becomes a major source of strain and tension in the following decade.
• 1890: Heligoland–Zanzibar Treaty with Germany. Britain gains the German colony of Zanzibar while giving up a small strategic island off the German coast, and agrees on boundaries in Africa.

• 1895: Venezuela Crisis. Border dispute with Venezuela causes major Anglo-American crisis when the United States intervenes to take Venezuela's side. It was resolved through arbitration and was last crisis that threatened war with the United States.
• 1894–96: Britain puts pressure on Turkey to stop its mistreatment of Christians. A series of escalating atrocities against the Armenians living in Turkey causes public outrage in Britain. All efforts to coordinate sanctions or punishments with the other Powers fail, and the Armenians get no help.
• 1895–96: Jameson Raid. Botched attempt at a coup to overthrow President Paul Kruger of the South African Republic, instigated by Cecil Rhodes. The result was to strengthen Afrikaner nationalism and embarrass Britain.
• 1896: January – Germany's Kaiser Wilhelm escalated tensions with his Kruger telegram of January 1896 congratulating President Kruger of the Transvaal for beating off the Jameson raid. German officials in Berlin had managed to stop the Kaiser from proposing a German protectorate over the Transvaal. The telegram backfired, as the British began to see Germany as a major threat and moved to friendlier relationships with France.

1897–1919

• 1897: Admiral Alfred von Tirpitz appointed German Naval Secretary of State; beginning of the transformation of German Navy from small, coastal defence force to a fleet meant to challenge British naval power. Tirpitz calls for Riskflotte (Risk Fleet) that would make it too risky for Britain to take on Germany as part of wider bid to alter the international balance of power decisively in the Reich"s favour.
• 1897: German Foreign Secretary Bernhard von Bülow calls for Weltpolitik (World politics). New policy of Germany to assert its claim to be a global as opposed to a European power. Germany abandons Bismarck-era policy of being a conservative power committed to upholding the status quo, and instead becomes a revisionist power intent on challenging and upsetting international order. It was now the policy of Germany to assert its claim to be a global power. The long-run result was the inability of Britain and Germany to be friends or to form an alliance.
• 1898: First Navy Law passed in Germany that commits the Reich to building up its fleet to achieve Tirpitz's vision.
• 1898: Convention for the Extension of Hong Kong Territory with China.
• 1898: Anglo-Egyptian control over Sudan established.
• 1898: Fashoda Incident threatens war with France over control of upper Nile River (in present-day eastern South Sudan); the French back down. The long-term British goal is to link South Africa to Egypt with the Cape to Cairo Railway. It would facilitate governance, give rapid mobility to the military, promote settlement and foster trade. Most of the railway is eventually built, but there were gaps.
• 1898: Spanish–American War. Britain maintains pro-American neutrality. Anglo-American relations began to improve markedly at the end of the 19th century.
• 1899: Britain endorses the "Open Door Policy" allowing the world access to Chinese markets.
• 1899: Bloemfontein Conference between Alfred Milner, the British High Commissioner for South Africa and President Paul Kruger of the Transvaal.

• 1899: Colonial Secretary Joseph Chamberlain's offer of an alliance with Germany is refused by Berlin.
• 1899: Beginning of the Second Boer War when the Transvaal (South African Republic) declares war on Britain.
• 1899: The first Hague Conference was a major effort to codify the rules for international peace. It set up machinery to help resolve international disputes. Britain and Russia used its procedures in resolving the Dogger Bank incident of 1904. It established a Permanent Court of Arbitration. It did little to slow the arms race in Europe. Its declaration banning the use of poison gas was simply ignored.
• 1900: British forces join in international rescue in Peking, China, & suppress the anti-Western Boxer Rebellion.
• 1900: Second Navy Law passed in Germany calling for huge increase in the size of the German Navy.
• 1901: Hay–Pauncefote Treaty with US nullifies Clayton–Bulwer Treaty of 1850; allows U.S. to build the Panama Canal & guarantees open passage for any nation. Panama Canal opens in 1914.

• 1902: Reports from Captain Watson, naval attaché to Germany indicate that the German build-up that had begun in 1898 is intended to build a fleet meant to challenge British sea power. Beginning of the Anglo-German naval race.
• 1902: The Anglo-Japanese Alliance is signed; in 1905 it is renewed and expanded; it is not renewed in 1923.
• 1903: King Edward VII, new to the throne but long familiar with France, makes a highly successful visit to Paris, turning hostility into friendship.
• 1903: Younghusband expedition to Tibet. Britain invades Tibet to counter supposed Russian influence at the court of the Dalai Lama that seems to be threatening India.
• 1904: Beginning of the Russo-Japanese War. Britain supports Japan while France and Germany support Russia. Britain shares signet (signals intelligence) with Japan against Russia. Due to shared intelligence with Japan, British decision-makers increasingly come to the conclusion that Germany is supporting Russia as part of a bid to disturb the balance of power in Europe.
• 1904: 8 April. Three agreements with France ("Entente cordiale") end many points of friction. France recognises British control over Egypt, while Britain reciprocates regarding France in Morocco. France drops exclusive fishery rights on the shores of Newfoundland and in return receives an indemnity and territory in Gambia (Senegal) and Nigeria. Britain drops complaints regarding the French customs régime in Madagascar. Spheres of influence are defines in Siam (Thailand). Issues regarding New Hebrides are settled in 1906. Which means doing we see its rights in Egypt, it became possible for the British to significantly extend their control. The Entente was negotiated between the French foreign minister, Théophile Delcassé, and the British foreign secretary, Lord Lansdowne.
• 1904: Convention with Tibet allowing a British trade mission to be established and is intended to pull Tibet within the British sphere of influence.
• 1904: Dogger Bank incident. Russian Baltic fleet en route to Korea to fight Japan accidentally fires on British fishing trawlers. Britain and Russia almost go to war. Crisis ends when Russia apologises and pays compensation.

• 1905: Persian Constitutional Revolution causes tension with Russia. Britain supports Persian liberals while Russia supports the Shah.
• 1906: Algeciras Conference ends the Moroccan Crisis in a diplomatic defeat for Germany as France took the dominant role in North Africa. The Crisis brought London and Paris much closer and set up the presumption they would be allies if Germany attacked either one.
• 1906: Britain reacted to Germany's accelerated naval arms race by major innovations, especially those developed by Lord Fisher. The launch of HMS Dreadnought rendered all other battleships technically obsolete and marked British success in maintaining both qualitative and quantitative lead in the naval race with Germany.
• 1906: Third Navy Law passed in Germany. Germany plans to build "all big gun" ships of its own to keep up with Britain in the naval race.

• 1907: Anglo-Russian Entente was achieved and outstanding disputes between Britain and Russia settled. It ended The Great Game regarding control of Tibet, Persia, and Afghanistan.
• 1907: Triple Entente with France and Russia, stands opposed to the Triple Alliance of Germany, Austria and Italy.
• 1908: Fourth Navy Law passed in Germany; British popular response was a clamour for more warship construction under the slogan "We want eight and won't wait" when it appears that Germany is winning the naval race.
• 1911: Reports from Captain Watson, naval attaché to Germany indicate growing power and efficiency of German warships, heavy guns and sailors.
• 1911: Agadir Crisis France strong-armed itself into seizing more control over Morocco. The German Foreign Minister Alfred von Kiderlen-Waechter was not opposed to these moves, but he felt Germany was entitled to some compensation elsewhere in Africa. He sent a small warship, made saber-rattling threats, and whipped up anger among German nationalists. France and Germany soon agreed on a compromise. However, the British cabinet was alarmed at Germany's aggressiveness toward France. David Lloyd George made a dramatic "Mansion House" speech that denounced the German move an intolerable humiliation. There was talk of war, and Germany backed down. Relations with Berlin remained sour.
• 1911: Reciprocity treaty lowering tariffs between Canada and US fails on surge of pro-British, anti-American sentiments led by Conservative Party.
• 1912: Fifth Navy Law passed in Germany Expanding the German fleet as a threat to the Royal Navy's control of the seas.
• 1912: Haldane Mission to Germany. Richard Haldane visits Berlin to meet with high officials in an attempt to end the naval race with Germany. Haldane's offer of a "naval holiday" in building warships ends in failure when the Germans attempt to link a "naval holiday" with a British promise to remain neutral if Germany should attack France; Admiral Tirpitz orders further naval construction.
• 1914: July Crisis triggered when Austria-Hungary submits ultimatum to Serbia containing terms meant to inspire rejection. Foreign Secretary Edward Grey tries hard to maintain peace and mediate a compromise, but falls short.
• 1914: 4 August- The king, in the name of Britain and his Empire declares war on Germany and Austria following German violation of the neurality of Belgium.
• 1914: Stalemate on Western Front, but Britain & dominions seize the overseas German colonies
• 1915: British passenger liner RMS Lusitania torpedoed without warning by German submarine and sinks in 18 minutes; 1,200 dead. Germany violated international law by not allowing passengers to escape.
• 1915: Treaty of London brings Italy into the war on the Allied state. Italy is secretly promised major gains at the expense of Austria-Hungary.
• 1916: Sykes–Picot Agreement is signed. Britain and France decide on spheres of influence if the Ottoman Empire should come to an end.
• 1917: 7 April. US declares war on Germany and Austria; does not actually join Allies and remains independent force; sends token army in 1917. A major factor in bringing the United States into war is the Zimmermann Telegram, a German proposal for anti-American alliances with Mexico and Japan that was intercepted, decoded and leaked by the British.
• 1917: Balfour Declaration is issued giving British support for a Jewish "national home" in Palestine.
• 1918: Britain accepts the Fourteen Points, the American statement of war aims.

• 1918: November. Britain and Allies defeat Germany, Austria-Hungary and Turkey; their empires dissolved (along with Russian Empire)
• 1919: Treaty of Versailles Prime Minister David Lloyd George was a key negotiator. In the Khaki Election of 1918, coming days after the Allied victory over Germany, Lloyd George promised to impose a harsh treaty on Germany. At the Versailles Conference, however, he took a much more moderate approach. France and Italy however demanded and achieved harsh terms, including German admission of guilt for starting the war (which humiliated Germany), and a demand that Germany pay the entire Allied cost of the war, including veterans' benefits and interest.
• 1919: League of Nations formed, with Britain an active member, along with the Dominions and India

1920–1934

• 1919: Greco-Turkish War begins. Britain was chief supporter of Greece, but it did poorly.
• 1919: War Secretary Winston Churchill introduces the Ten Year Rule that military spending is to be based on the assumption that there will be no major war for the next ten years. The Ten Year Rule leads to a huge decline in military spending.
• 1920: Leonid Krasin visits London to meet Lloyd George. First official contact between Soviet Russia and Britain.
• 1921: Anglo-Soviet Trade Agreement is signed. First treaty between Britain and Soviet Russia.
• 1921: Franklin-Bouillon Agreement is signed. France supports Turkey in the Greco-Turkish War while Britain continues to support Greece.
• 1922: Washington Naval Conference concluding in the Four-Power Treaty, Five-Power Treaty, and Nine-Power Treaty; major naval disarmament for 10 years with sharp reduction of all major navies. Britain abandons claim to have navy "second to none", and recognises United States Navy as equal. The costs of naval races with the U.S. and Japan are prohibitively expensive for a British economy weakened by World War I. The relative naval strengths of the major powers are fixed at GB = 5, US = 5, Japan = 3, France = 1.75, Italy = 1.75. Britain does not build up to its allowed maximum. The powers will abide by the treaty for ten years, then begin a naval arms race.
• 1922: League of Nation awards Britain a mandate to control Palestine, which it had conquered from the Ottoman Empire in 1917. The mandate lasts until 1948.

• 1922: Alliance with Japan ends; Canada and Australia disliked the treaty, as did the U.S.
• 1922: Chanak Crisis. Britain almost goes to war with Turkey. Some of the Dominions refuse to promise to war if Britain does, which comes as a major shock in Whitehall. The intention of Lloyd George to go to war with Turkey causes the downfall of his government.
• 1923: The British government renegotiated its £978 million war debt to the US Treasury by promising regular payments of £34 million for ten years then £40 million for 52 years. The idea was for the US to loan money to Germany, which in turn paid reparations to Britain, which in turn paid off its loans from the US government. In 1931 all German payments ended, and in 1932 Britain suspended its payments to the US. All the First World War debts were finally repaid after 1945.
• 1923: France occupies the Ruhr following German default in reparations. Britain wanted Germany's economy to revive, so could make reparation payments and increased trade. France rejected Britain's argument, and along with Belgium occupied the Ruhr 1922–25. British policy was then uncertain, until it hit on the idea of inviting the Americans to resolve the problem, which was done with the Dawes Plan.
• 1923: Treaty of Lausanne with Turkey. Britain was forced to make major concessions to the Turks as compared to the previous Treaty of Sèvres of 1920.
• 1924: London conference between Labour Prime Minister Ramsay MacDonald and French Premier Édouard Herriot. Britain forced France to reduce the amount of reparations to be collected from Germany. The British diplomat Sir Eric Phipps commented that "The London Conference was for the French 'man in the street' one long Calvary as he saw M. Herriot abandoning one by one the cherished possessions of French preponderance on the Reparations Commission, the right of sanctions in the event of German default, the economic occupation of the Ruhr, the French-Belgian railroad Régie, and finally, the military occupation of the Ruhr within a year".
• 1924: The Geneva Protocol, (Protocol for the pacific settlement of international disputes) was a proposal to the League of Nations presented by Prime Minister Ramsay MacDonald, and his French counterpart Édouard Herriot. It set up compulsory arbitration of disputes, and a created a method to determine who was the aggressor in international conflicts. All legal disputes between nations would be submitted to the World Court. It called for a disarmament conference in 1925. Any government which refused to comply in a dispute would be named an aggressor. Any victim of aggression was to receive immediate assistance from the League members. McDonald lost power and the new Conservatives government condemned the proposal, fearing it would lead to conflict with the United States. Washington also opposed it, and so did all the British dominions. The proposal was tabled in 1925 and never went into effect.
• 1924: Labour government establishes diplomatic relations with Soviet Russia.
• 1925: Locarno Treaties normalise the status of Germany, although the provisions of the Versailles Treaty still apply; begins a decade of British efforts to stabilise a new European status quo, hoping that stability, plus trade, would prevent another war.
• 1926: Dispute with Turkey over Mosul ends. Turkey ends claim to Mosul region of Iraq.
• 1927: British police raid ARCOS office in London. Relations with the Soviet Union are broken off following discovery of the Soviet spy ring operating out of the ARCOS building.
• 1929: MacDonald's Labour government restores relations with the Soviet Union.
• 1929: MacDonald visits the United States; first visit to the US by a sitting British Prime Minister.
• 1929–31: Labour Foreign Minister Arthur Henderson gives strong support to League of Nations.
• 1931: Statute of Westminster recognises the full independence to the Dominions.
• 1932: British policy in the Far East faces a crisis in 1932, when the Japanese attacked Shanghai. Of all British foreign investment, 6% is in China and two-thirds of that is in Shanghai. As a result, the Ten Year Rule is dropped. (It said the military planning should assume that no war would take place in the next ten years.) The Cabinet authorises a modest increase in the Royal Navy budget based on the assumption that there might a war with Japan sometime within the next decade, through constraints imposed by the Great Depression limit how much money will be spent. Beginning of British rearmament.
• 1932: Britain suspends its World War I debt payments to the United States.
• 1934: A secret report by the Defence Requirements Committee identifies Germany as the "ultimate potential enemy"; calls for Continental expeditionary force of five mechanised divisions and fourteen infantry divisions. Budget restraints prevent formation of this large force.
• 1934: Beginning of the "air panic" of 1934–35, where exaggerated claims of German air strength are made in the British press. Royal Air Force becomes the main beneficiary of rearmament.

1935–1945

• 1935: The Peace Ballot is held with 11.5 million votes cast. The strong affirmative vote was ambiguous and the campaign was distorted by bias. Political leaders ignored it as an expression of wishful thinking rather than a serious statement of foreign policy.
• 1935: Stresa Front formed following summit between Prime Minister Ramsay MacDonald, French Premier Pierre Laval and Italian Prime Minister Benito Mussolini vaguely sought to oppose any challenge to the Treaty of Versailles via force. Mussolini mistakenly feels that Britain has no interest in Ethiopia.
• 1935: Anglo-German Naval Agreement signed in London. It is meant to avoid a repeat of the pre-1914 Anglo-German naval race.
• 1935: Italy invades Ethiopia. Beginning of a crisis in Anglo-Italian relations as Britain makes half-hearted attempts to uphold collective security. Mussolini threatens of war against Britain.

• 1935: Hoare–Laval Pact with France proposes to appease Italy and evades League sanctions against Italy for invading Ethiopia. The proposal was approved by the cabinet but public reaction is highly negative and Foreign Minister Samuel Hoare is forced to resign, replaced by Anthony Eden.
• 1936: Remilitarization of the Rhineland. Germany remilitarises the German Rhineland in explicit violation of the Versailles and Locarno treaties which said the area had to remain without soldiers. The Baldwin government protested, but valued peace highly and did not take action. France had sufficient military superiority to expel Germany from the Rhineland but instead chose to follow Britain and do nothing. It lacked confidence in its military and feared another costly war.
• 1936–39: British opinion is deeply split on the Spanish Civil War with the government tending to favour the right-wing Nationalists while intellectuals and unions favoured the Republic because it was anti-Fascist. Communists were leaders in protest efforts, and enlisted 2500 British and Irish volunteers go to Spain to fight for the Republic; 500 were killed. The government joins major powers in proclaiming neutrality and opposes arms shipments to either side, fearing the war might spread. Nevertheless, Germany and Italy supply the Nationalists and the USSR supplies the Republicans. The Nationalists under Francisco Franco are completely victorious in 1939.
• 1937: Japanese planes attack British gunboats in the Yangtze River and machine-gun the car of the British Ambassador to China, Sir Hughe Knatchbull-Hugessen, who is badly injured. As these attacks occurred at the same time as the sinking of USS Panay, Britain suggests that an Anglo-American blockade of Japan as a response. The American President Franklin Roosevelt refuses the British offer and instead accepts Japanese apology, through he does allow the secret Anglo-American naval talks to begin in early 1938.
• 1938: Mexican oil expropriation. The government of Lázaro Cárdenas nationalises land owned by British oil companies in Mexico.
• 1938: Anglo-Italian Easter Accords are signed. Britain tries to restore relations with Italy.

• 1938: Hitler threatens war over the alleged mistreatment of ethnic Germans in the Sudetenland, a part of Czechoslovakia. Intense appeasement efforts by Britain and France to avoid war by concessions to Germany. Czechoslovakia is not consulted.
• 1938: Britain and France signed the Munich Agreement with Nazi Germany. Prime Minister Neville Chamberlain promises it means "peace in our time." Historians differ sharply; some argue the appeasement was cowardice; others argue it saved Britain, which was not prepared for war with Germany.
• 1939: 15 March - Appeasement policy ends as Germany seizes all of Czechoslovakia
• 1939: 31 March - Prime Minister Chamberlain issues "guarantee" of Polish independence in the House of Commons in co-operation with France; they will go to war should Polish independence be threatened.

• 1941: The United States begins Lend-Lease to support Allied war effort; $31.4 billion is given away to Britain and $11.3 billion to the Soviet Union. Canada in a separate programs gives $4.7 billion. Unlike American aid in 1917–18, Lend Lease is not a loan and does not have to be repaid.
• 1941, 22 June – Germany launched Operation Barbarossa invading the USSR, which became one of the Allies of World War II fighting against the Axis powers.
• 1941: Prime Minister Churchill agrees on Atlantic Charter with President Roosevelt.

• 1942: Britain and USSR agree that after victory Poland's boundaries would be moved westward, so that the USSR took over lands in the east while Poland gained lands in the west that had been under German control. They agreed on the "Curzon Line" as the boundary between Poland and the Soviet Union and the Oder-Neisse line would become the new boundary between Germany and Poland. The proposed changes angered the Polish government in exile in London, which was not consulted.
• 1943: A. J. P. Taylor asserts, "1943 was the year when world leadership moved from Great Britain to the United States."
• 1943: The Casablanca Conference in Morocco, 14–23 January, brought together Churchill, Roosevelt and Charles de Gaulle. The Allies announced a policy of "unconditional surrender" from the Axis powers.
