The People's Parliaments or People's Assemblies (Latvian: Tautas Saeima; Lithuanian: Liaudies Seimas) were puppet legislatures put together after the show elections in Estonia, Latvia, and Lithuania to legitimize the occupation by the Soviet Union in July 1940.
[1] In all three countries, the elections to the parliaments followed the same script, dictated by functionaries in Moscow and borrowed from the examples of the incorporation of the Belarusian and Ukrainian lands into Soviet Union in the aftermath of the invasion of Poland in 1939.
[2] On 15 and 16 June 1940, the Soviet Union presented ultimatums to all three Baltic states, which were then invaded by the Red Army.
The parliaments also elected their representatives to go to Moscow and personally present their case in front of the Supreme Soviet.
[3] Other acts adopted in these early sessions concerned nationalization of virtually all larger enterprises, real estate, and land, and other Sovietization policies.
