The new Soviet republic initially consisted of seven districts: Baranavičy, Viciebsk, Homieĺ, Hrodna, Mahilioŭ and Smolensk. On 30 January, the republic announced its separation from the Russian SFSR and renaming as the "Soviet Socialist" Republic of Byelorussia (SSRB). This was conferred by the First Congress of deputies, composed of workers, soldiers and Red Army men, which met on 2–3 February 1919, to adopt a new Socialist constitution. The Red Army continued its westward advance, capturing the city of Grodno on New Year's Day 1919, Pinsk on 21 January, and Baranovichi on 6 February 1919, thereby enlarging the SSRB.
