Nikita Khrushchev - Wikipedia

On September 11, 1971 Nikita Khrushchev, Soviet premier, dies of a heart attack at 77. From the article:

"Khrushchev was born in 1894 in the village of Kalinovka, which is close to the present-day border between Russia and Ukraine. He was employed as a metal worker during his youth, and he was a political commissar during the Russian Civil War. With the help of Lazar Kaganovich, he worked his way up the Soviet hierarchy. He supported Joseph Stalin's purges, and approved thousands of arrests. In 1938, Stalin sent him to govern Ukraine, and he continued the purges there. During what was known in the Soviet Union as the Great Patriotic War (Eastern Front of World War II), Khrushchev was again a commissar, serving as an intermediary between Stalin and his generals. Khrushchev was present at the bloody defense of Stalingrad, a fact he took great pride in throughout his life. After the war, he returned to Ukraine before being recalled to Moscow as one of Stalin's close advisers.

Stalin's death in 1953 triggered a power struggle, from which Khrushchev ultimately emerged victorious. On 25 February 1956, at the 20th Party Congress, he delivered the "Secret Speech", which denounced Stalin's purges and ushered in a less repressive era in the Soviet Union. His domestic policies, aimed at bettering the lives of ordinary citizens, were often ineffective, especially in agriculture. Hoping eventually to rely on missiles for national defense, Khrushchev ordered major cuts in conventional forces. Despite the cuts, Khrushchev's rule saw the most tense years of the Cold War, culminating in the Cuban Missile Crisis.

Khrushchev's popularity was eroded by flaws in his policies. This emboldened his potential opponents, who quietly rose in strength and deposed the Premier in October 1964. However, he did not suffer the deadly fate of previous Soviet power struggles, and was pensioned off with an apartment in Moscow and a dacha in the countryside. His lengthy memoirs were smuggled to the West and published in part in 1970. Khrushchev died in 1971 of a heart attack."
