Khrushchev

Francis Spufford Khrushchev started off a miner’s son and had one of those rocket rides in the social stratosphere that could happen once Stalin had got rid of all the old Bolsheviks and needed a completely new political class. He went being from being a semi-literate party member out in the country to the deputy mayor of Moscow in about five years, and he finally ended up as one of Stalin’s inner circle. He worked closely with Stalin for nearly 20 years and approved thousands of arrests and executions and then went on to lead Russia during the Cold War. (Source)
