The Great Purge, which took place from 1936 to 1938, was a period of intense political repression in the Soviet Union. During this time, millions of people were arrested and executed, often on the basis of false accusations. It is estimated that as many as 7 million people were killed during the Great Purge.
The collectivization of agriculture, which began in the early 1930s, also resulted in the deaths of millions of people. In an effort to force peasants to join collective farms, Stalin's government confiscated their land and animals, and in many cases, they were forcibly deported to Siberia or other remote areas. It is estimated that as many as 5 million people died as a result of the collectivization of agriculture.
The Gulag was a system of forced labor camps that operated in the Soviet Union from the 1930s to the 1950s. Millions of people were sent to the Gulag, including political prisoners, criminals, and those who were considered to be "enemies of the state." Conditions in the Gulag were extremely harsh, and it is estimated that as many as 2 million people died there.
Stalin's rule was marked by a brutal disregard for human life. His policies resulted in the deaths of millions of innocent people, and his legacy continues to be a source of controversy and debate.
