After the annexation of Baltic states, Lithuania, Latvia and Estonia were transformed into the Lithuanian SSR (July 13), Latvian SSR (July 21) and Estonian SSR (also July 21), and were formally adjoined to the Soviet Union on 3, 5 and 6 August respectively. The final republic was the Moldovian SSR that merged the large territory of Bessarabia with the Moldovian ASSR previously part of the Ukrainian SSR.
