Encouraged by their success, in Smolensk on 30–31 December 1918, the Sixth Western Oblast Party conference met and announced its split from the Russian Communist Party, proclaiming itself as the first congress of the Communist Party of Byelorussia (CPB(b)). The next day, the Soviet Socialist Republic of Byelorussia was proclaimed in Smolensk, terminating the Western Commune, and on 7 January it was moved to Minsk. Aleksandr Myasnikyan emerged as head of the All-Byelorussian Central Executive Committee and Zmicier Žylunivič as head of the provisional government.
