The Convention People's Party (CPP) (Akan: Apam Nkorɔfo Kuw) is a socialist political party in Ghana based on the ideas of the first President of Ghana, Kwame Nkrumah. The CPP was formed on 12 June 1949 by Kwame Nkrumah to campaign for the independence of the Gold Coast. It was the governing party under Nkrumah of the autonomous British colony of the Gold Coast from 1951 to 1957, and independent Ghana from 1957 to 1966. In 1964 the constitution was changed to make the CPP the only legal party in Ghana, making the nation a one-party state. The party was banned after the 24 February 1966 coup d'état by the National Liberation Council. Parties following in its tradition have used various names. The party was reformed from some of the Nkrumah factions in 1996.
