The 1868 United Kingdom general election was the first after passage of the Reform Act 1867, which enfranchised many male householders, thus greatly increasing the number of men who could vote in elections in the United Kingdom. It was the first election held in the United Kingdom in which more than a million votes were cast; nearly triple the number of votes were cast compared to the previous election in 1865.
This was the last general election at which all seats were taken by only the two leading parties, although the parties at the time were loose coalitions and party affiliation was not listed on registration papers.
