Answer:
True
Step-by-step explanation:
In order to prevent a possible coup or an assassination, Stalin got rid of dissidents by sending them to Siberia. This was done through a government agency known as "Gulag." The dissidents were sent to forced-labour camps originally established by Lenin. These were particularly used from the 1930s to the early 1950s. The Gulag was a major instrument of political repression during the Soviet years.
