Yumjaagiin Tsedenbal

Yumjaagiin Tsedenbal (Mongolian: Юмжаагийн Цэдэнбал) (1916-1991) was a communist politician and tenth president of the People's Republic of Mongolia, from June 11, 1974 to August 23, 1984. He was elected by the People's Revolutionary Party from Mongolia

Tsedenbal successfully purged his political rivals: Dashiin Damba in 1958–59, Daramyn Tömör-Ochir in 1962, Luvsantserengiin Tsend in 1963 and the so-called Lookhuuz - Nyambuu - Surmaajav "anti-party group" in December 1964 without the need to summarily execute them. He held this position until June 11, 1974, when he finally became head of state, thus becoming the supreme ruler of the People's Republic of Mongolia.
