The Latvian Popular Front was founded in June 1988. On 4 October, Gorbachev replaced Boris Pugo, the "old guard" leader of the Communist Party of Latvia, with the more liberal Jānis Vagris. In October 1988 Vagris bowed to pressure from the Latvian Popular Front and legalized flying the former carmine red-and-white flag of independent Latvia, and on 6 October he passed a law making Latvian the country's official language.[17]
