Step-by-step explanation:
Stalin ruled by terror and with a totalitarian grip in order to eliminate anyone who might oppose him. He expanded the powers of the secret police, encouraged citizens to spy on one another and had millions of people killed or sent to the Gulag system of forced labor camps. During the second half of the 1930s, Stalin instituted the Great Purge, a series of campaigns designed to rid the Communist Party, the military and other parts of Soviet society from those he considered a threat.
