John Kevan McDowall was a Scottish solicitor and politician during the early 20th century. He lived and practiced as a solicitor in Glasgow for the majority of his life. He was the first and only leader of the Scottish Party, which later merged with the National Party of Scotland (NPS) to form the Scottish National Party (SNP) in 1934.
McDowall was a descendant of the Kevan family. While their heritage is uncertain, in his own book, Carrick Gallovidian, McDowall presents the theory that the family originated in Wigtown Bay, near Galloway, as early as the fifteenth century ("[the family] occurs in a charter of 1421 as Cavens").
McDowall became a member of the Unionist Party, the Glasgow Unionist Association (GUA) and the Cathcart Unionist Association (CUA). In June 1932 the CUA made him Chairman of an 'Imperial Committee', which was in favour of Scottish home rule. The committee organised meetings to support home rule, it also produced a manifesto that proposed replacing the Westminster Parliament with an Imperial one, where representatives from the Empire would all convene. The manifesto also proposed the establishment of separate Parliaments for Scotland, England and Wales.
This provoked outrage from the Unionist Party and McDowall was accused of disloyalty and unconstitutional practices. McDowall, joined by over thirty other pro- Home Rule rebels, resigned from the Unionist Party to found the Scottish Party. The Scottish Party was a center-right, liberal conservative party which was pro-Imperial Federalism and pro-Scottish Independence. Many high standing members of Scottish society enlisted to the party, including James Graham, 6th Duke of Montrose (who was made the party's chairman), John Bannerman, Sir Henry Keith, Sir Daniel Stevenson and Sir Alexander MacEwan. As the party never actually fielded any candidates, it acted as more of a think tank than a political party, its membership never exceeded 1000.
