Answer
The demotion of Georgy Zhukov, a renowned Soviet military leader, by Joseph Stalin following World War II can be attributed to several factors. Zhukov's immense popularity among the Soviet populace and his independent decision-making during the war made him a potential threat to Stalin's authority. Stalin, known for his paranoia and desire for absolute control, saw Zhukov's influence as a challenge to his leadership and sought to diminish his power.
