Following the death of Brezhnev and his successor Yuri Andropov, Chernenko was elected General Secretary in February 1984 and made Chairman of the Presidium of the Supreme Soviet in April 1984.
Chernenko was born to a poor family of Ukrainian ethnicity in the Siberian village of Bolshaya Tes (now in Novosyolovsky District, Krasnoyarsk Krai) on 24 September 1911.
In the early 1940s, he began a close relationship with Fyodor Kulakov and was named Secretary of the Territorial Party Committee for Propaganda.
The turning point in Chernenko's career was his assignment in 1948 to head the Communist Party's propaganda department in the Moldavian Soviet Socialist Republic.
There, he met and won the confidence of Leonid Brezhnev, the first secretary of the Moldavian branch of the Communist Party from 1950 to 1952 and future leader of the Soviet Union.
In 1971, Chernenko was promoted to full membership in the Central Committee: overseeing Party work over the Letter Bureau, dealing with correspondence.
After Brezhnev's death in November 1982, there was speculation that the position of General Secretary would fall to Chernenko, but he was unable to rally enough support for his candidacy within the Party.
Ultimately, KGB chief Yuri Andropov, who had been more mindful of Brezhnev's failing health, eventually won the position.
The one major personnel change Chernenko made was the dismissal of the Chief of the General Staff, Marshal Nikolai Ogarkov.
[8] In 1980 the United States led an international boycott of the Summer Olympics held in Moscow in protest at the Soviet invasion of Afghanistan.
On 8 May 1984, under Chernenko's leadership, the USSR announced its intention not to participate in the Games, claiming "security concerns and chauvinistic sentiments and an anti-Soviet hysteria being whipped up in the United States".
In his letter to Stalin's daughter Svetlana Alliluyeva, he wrote about "the upcoming restoration of justice in relation to the memory and heritage of I.V.
Historian John Lewis Gaddis described him as "an enfeebled geriatric so zombie-like as to be beyond assessing intelligence reports, alarming or not" when he succeeded Andropov in 1984.
During the summer, his doctors sent him to Kislovodsk for the mineral spas, but on the day of his arrival at the resort Chernenko's health deteriorated, and he contracted pneumonia.
Chernenko's illness was first acknowledged publicly on 22 February 1985 during a televised election rally in Kuibyshev Borough of northeast Moscow, where the General Secretary stood as candidate for the Supreme Soviet of the Russian SFSR, when Politburo member Viktor Grishin revealed that the General Secretary was absent in accordance with doctors' advice.
[15] Two days later, in a televised scene that shocked the nation,[16] Grishin dragged the terminally ill Chernenko from his hospital bed to a ballot box to vote.
On 28 February 1985, Chernenko appeared once more on television to receive parliamentary credentials and read out a brief statement on his electoral victory: "the election campaign is over and now it is time to carry out the tasks set for us by the voters and the Communists who have spoken out".
Upon being informed in the middle of the night of his death, U.S. President Ronald Reagan is reported to have remarked, "How am I supposed to get anyplace with the Russians if they keep dying on me?
