By 1906, the Conservatives had another split, this time about the issue of 'tariff reform' and as a result, the party was defeated in a landslide at the 1906 General Election by the Liberal Party. In 1912, the Conservative Party formally joined with the Liberal Unionist Party to create the modern-day Conservative and Unionist Party, however this is usually shortened to Conservative Party. The party was in a coalition with the Liberal Party from 1916 to 1922, and was mostly in power from 1922 to 1929 under Stanley Baldwin. During the 1920s, the Labour Party replaced the Liberals as the Conservative's main political opponent.
