You don't own history)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)The Treaty of Welawa (German: Vertrag von Wehlau) was a political act signed in the eastern Prussian town of Welawa (German: Wehlau) between Poland and Brandenburg-Prussia during the Swedish Deluge on September 9, 1657.
Margrave Frederick William I, the "Great Elector", of the Brandenburg Hohenzollerns, promised King John II Casimir of Poland to cancel his alliance with King Charles X Gustav of Sweden. In return he was given full sovereignty over Ducal Prussia and the territory ceased to be a Polish fief. In case of an end to Hohenzollern rule in Prussia, Ducal Prussia was to return to Poland as its integral part.
The treaty was amended by the Treaty of Bydgoszcz of November 6, 1657.
