The post was officially created on 7 April 1934 with the foundation of the SNP. The role was titled Chairman of the Scottish National Party from 1934 until 1969, with the first chairman, Alexander MacEwen, appointed to the office in 1934. In 1969 the title of chairman was replaced with that of National Convener, with William Wolfe the first person elected as National Convener. The post gained its current title of Leader at the SNP spring conference on 24 April 2004.
While Gordon Wilson had the longest uninterrupted spell as leader, lasting just over eleven years from 1979 to 1990, Alex Salmond has been the party's longest-serving leader overall, serving twenty years and two months across two spells as leader.
