Sifton was first elected to the North-West Territorieslegislature in 1885. In 1903, he became territorial Chief Justice, and in 1907 became Alberta's chief justice. In 1910, he was recruited by the Alberta Liberal Party to succeed Alexander C. Rutherford as Premier. The party had been seriously divided over allegations of wrongdoing regarding railway construction. Sifton held the party together, and led it to victory in the 1913 and 1917 provincial elections. In 1916, his government gave women the right to vote, and passed temperance legislation that severely limited the sale of alcohol in the province.
