How did Stalin leave power?

He never lost power, Stalin was a dictator

Explanation:

Stalin, who grew increasingly paranoid in his later years, died on March 5, 1953, at age 74, after suffering a stroke. His body was embalmed and preserved in Lenin's mausoleum in Moscow's Red Square until 1961, when it was removed and buried near the Kremlin walls as part of the de-Stalinization process initiated by Stalin's successor Nikita Khrushchev (1894-1971).
