Robert Bontine Cunninghame Graham (London, 24 May 1852 – Buenos Aires, 20 March 1936) was a Scottish politician, writer, journalist and adventurer. He was a Liberal Party Member of Parliament (MP); the first-ever socialist member of the Parliament of the United Kingdom; a founder, and the first president, of the Scottish Labour Party (1888-1893); a founder of the National Party of Scotland in 1928; and the first president of the Scottish National Party in 1934. Graham was a strong supporter of Scottish independence and in 1886 had helped establish the Scottish Home Rule Association, and while in the House of Commons made several attempts to persuade fellow MPs of the desirability of a Scottish parliament. On one occasion Graham joked that he wanted a "national parliament with the pleasure of knowing that the taxes were wasted in Edinburgh instead of London."
While in the House of Commons Graham became increasingly more radical and went on to found the Scottish Labour Party with Keir Hardie. Graham left the Liberal Party in 1892 to contest the general election in a new constituency as a Labour candidate. He supported workers in their industrial disputes and was actively involved with Annie Besant and the Matchgirls Strike and the 1889 Dockers' Strike. In July 1889 he attended the Marxist Congress of the Second International in Paris with James Keir Hardie, William Morris, Eleanor Marx and Edward Aveling. The following year he made a speech in Calais that was considered by the authorities to be so revolutionary that he was arrested and expelled from France.
