Mao Zemin, younger brother of Communist leader Mao Zedong, was executed on this date in 1943.
A party cadre since 1921, the non-chairman Mao served a variety of economic leadership posts for the Red Army.

To Mao’s grief, this “King of Xinjiang” saw in the unfolding global war an opportunity to realign.
After the German invasion of the USSR in 1941, Sheng boldly flipped his affiliation from Moscow to the nationalist Kuomintang government with which he had theretofore maintained only the frostiest of relations. Crackdowns on Communists ensued too, and both Mao Zemin and Chen Tanqiu were both arrested, tortured, and executed as a result.
