Konstantin Chernenko, Russian soldier and politician, Head of State of The Soviet Union (born 1911)

Konstantin Ustinovich Chernenko was a Soviet politician who served as the General Secretary of the Communist Party of the Soviet Union from 1984 until his death a year later.

The Constitution of the Soviet Union recognised the Presidium of the Supreme Soviet and the earlier Central Executive Committee (CEC) of the Congress of Soviets as the highest organs of state authority in the Union of Soviet Socialist Republics (USSR) between legislative sessions. Under the 1924, 1936 and 1977 Soviet Constitutions these bodies served as the collective head of state of the Soviet Union. The chairman of these bodies personally performed the largely ceremonial functions assigned to a single head of state but was provided little real power by the constitution.
