What was the political and econimic system like in the Soviet Union? (During the 1940s-50s)?

Question

the ones established by Stalin?

Why was it considered "totalitarian" too?

Answer 1

It was a political dictatorship with a Marxist economy. Stalin served as General Secretary of the Communist Party. That party was assured the right to govern under Article Six of the Treaty of Union which created the Union of soviet Socialist Republics. The economy was based on the model set down by Karl Marx and Frederich Engels in "The Communist Manifesto". Under such a system, all means of production are owned by the State.
Stalin ruled absolutely. Any challenge to his authority was met by swift and sure punishment. From death to imprisonment in a labor camp. He even forced one of the co-founders of Soviet Russia, Leon Trotsky, into exile and hired someone to kill Trotsky many years later in Mexico.
Here's the odd thing. Stalin wasn't a Russian. He was from the republic of Georgia, which lies south of Russia. Marx and Engels were both Germans. Lenin (the prime creator of the Soviet Union) was Russian. But, Leon Trotsky was from Staten Island in New York City. So, for over 70 years, the Russian people had to live under a system which was truly built by foreigners.
