Answer:
From 1919 to 1939, Russia (later the Soviet Union) was governed by the Communist Party through a system of socialist government structures. Here are some of the main government structures during this period:
1. Soviet government: The highest government body in the Soviet Union was the Supreme Soviet, which was composed of two chambers: the Soviet of the Union and the Soviet of Nationalities. The Supreme Soviet was responsible for making and enforcing laws.
2. Communist Party: The Communist Party was the ruling party of the Soviet Union. It had control over all government institutions and was responsible for implementing the policies of the Soviet government.
3. People's Commissariats: The People's Commissariats, also known as the Soviet ministries, were responsible for various sectors of the economy and society, such as agriculture, education, and defense.
4. Secret Police: The Soviet secret police, first known as the Cheka and later as the NKVD, were responsible for maintaining order and suppressing dissent within the Soviet Union.
5. Local government: The Soviet Union was divided into various regions, each of which had its own local government structure. These structures were responsible for implementing Soviet policies at the local level.
Overall, the Soviet government structures during this period were highly centralized and authoritarian, with the Communist Party at the center of power.
