Answer
Georgy Zhukov, a prominent Soviet military commander, was a key figure in the ousting of Lavrentiy Beria from power in 1953. Zhukov had been a close ally of Beria during the Stalin era, but he had grown increasingly critical of Beria's policies and power grabs. When Beria was arrested on charges of treason and corruption, Zhukov played a key role in ensuring that he was removed from power and executed.
