(1912–1965) Following the merger of the Conservatives and Liberal Unionists to create the modern Conservative and Unionist Party in England and Wales, a committee was formed of the National Union of Conservative Associations for Scotland and regional Liberal Unionist associations which recommended a merger in Scotland. This was agreed in December 1912, creating the Scottish Unionist Association and the Unionist Party. From 1918 and through the 1920s, the Labour Party became more prominent, displacing the Liberals as one of the two main parties in Scottish politics. The Unionist Party had a number of electoral successes, topping the poll in Scotland in a number of elections from the 1930s to 1950s.

The modern Scottish Conservative and Unionist Party, as part of the wider UK Conservative Party, came into existence from this point. However its electoral fortunes continued to decline throughout the 1960s.
