Nikita Khrushchev
Khrushchev's removal in 1964 was a result of political opposition within the Soviet leadership, citing economic failures and his handling of the Cuban Missile Crisis. His ousting marked a shift in Soviet leadership dynamics. After his removal in 1964, he lived a relatively quiet life, writing his memoirs and staying out of politics. His later years were marked by a retreat from the public eye until his death in 1971.
