Question

How did Stalin secure power in the Soviet Union

Answer 1

The best answer would be c.he controlled through terror and intimidation.

Tree elements were important to the maintenance of Stalin's dictatorship: Censorship and propaganda; Purges and Terror.  In August 1936, the Great Purge was launched; other show trials took place in 1937 and 1938. The Great Purge was undertaken by the NKVD (secret police), led by Genrikh Yagoda. He was replaced later in 1936 by Nikolai Ezhov, whose more extreme methods began a Great Terror. In 1937, this spread to include a purge of the officer corps of the armed forces, as well as of Communist Party officials. Once started, the Great Purge developed a momentum of its own. In the regions away from Moscow, local party bosses used it to further their own positions and there is evidence to suggest that ordinary people saw the punishment of middle-class experts as part of a social revolution that would give them better jobs. As a result of the Great Purge, several million people were arrested and large numbers were executed or sent to the Gulag.
