I've been reading a little online about Marshal Georgy Zhukov and his roles through World War II, after the war, and post-Stalin. He seems to have mostly held his power through these periods, but suddenly, in 1957, upon return from a foreign trip to Yugoslavia, he was accused of "non-party behavior" and stripped of his positions, forced into retirement, only six months after his crucial support kept Khrushchev in power.
What happened in those six months, and how did someone who survived Stalin's purges fall to post-Stalin politics?
In this previous r/Askhistorians thread, u/Georgy_K_Zhukov touches on the reasons for Georgy Zhukov's fall from grace under Khrushchev (as well as a prior fall from grace under Stalin).
