The Burma Socialist Programme Party (BSPP), also referred to as the Lanzin Party, was the ruling political party of Burma from 1962 to 1988 and the country's sole legal party from 1964 to 1988. Party chairman Ne Win overthrew the country's democratically elected government in a coup d'état on 2 March 1962. For the next 26 years, the BSPP governed Burma under a totalitarian military dictatorship, until mass protests in 1988 pressured party officials to adopt a multi-party system.
