Overview
The Unionist Party was the main centre-right political party in Scotland between 1912 and 1965.
Independent of, although associated with, the Conservative Party in England and Wales, it stood for election at different periods of its history in alliance with a small number of Liberal Unionist and National Liberal candidates. Those who became members of parliament (MPs) would take the Conservative Whip at Westminster as the Ulster Unionists did until 1972. At Westminster, the differences between the Scottish Unionist and the English party could appear blurred or non-existent to the external casual observer, especially as many Scottish MPs were prominent in the parliamentary Conservative Party. Examples include party leaders Bonar Law (1911–1921 and 1922–1923) and Sir Alec Douglas-Home (1963–1965), both of whom served as Prime Minister of the United Kingdom.
The party traditionally did not stand at local government level but instead supported and assisted the Progressive Party in its campaigns against the Labour Party. This relationship ended when the Conservatives started fielding their own candidates, who stood against both Labour and the Progressives.
Origins
The origins of the Scottish Unionist Party lie in the 1886 split of the Liberal Party and the emergence of the Liberal Unionists under Joseph Chamberlain. The Union in question was the 1800 Irish Union, not that of 1707. Before this, the Tory party in Scotland had never achieved parity with the dominant Whig and Scottish Liberal ascendancy since the election reforms of 1832. The Liberal Unionists quickly agreed to an electoral pact with the Tories, and in Scotland this overcame the former electoral dominance of the Scottish Liberals.
