How did Yury Andropov rise from KGB chairman to leader of the Soviet Union?

Yury Andropov’s rise to the leadership of the Soviet Union was a calculated progression through the Communist Party hierarchy, bolstered by his long tenure as head of the KGB.

After serving as ambassador to Hungary, where he coordinated the Soviet invasion, Andropov returned to Moscow and rose rapidly through the party ranks. He was appointed head of the KGB in 1967, a position he used to establish the agency as the party's primary security watchdog. His influence grew significantly as he oversaw the suppression of political dissidents and recruited elite members from the party establishment.12

In 1973, Andropov was elected to the Politburo, cementing his status as a top-tier official. As the health of Soviet leader Leonid Brezhnev declined, Andropov strategically positioned himself for succession. He resigned from his KGB post in 1982 and was chosen by the Central Committee to succeed Brezhnev as general secretary on November 12, 1982. He further consolidated his authority by becoming chairman of the Presidium of the Supreme Soviet in 1983.12
