Leonid Breznev's political life
Ascent within the Communist Party of the Soviet Union
During the 1930s, Stalin carried out a policy of repression and persecution to eliminate opposition and dissidents within the USSR. The majority of the victims were members of the party, of the armed and professionals. Those members of the PCUS who survived the Stalinist purges had a fast political ascent within the party during the following years.
Thus, in 1939, after occupying different local positions (such as the direction of the Metallurgical Institute of Dneprodzerzhinsk) Brézhnev was appointed party secretary at Dnipropetrovskone of the largest cities in the region.
During World War II, his rise within the party was reflected in his rise in military rank. At the end of the war, He dedicated himself to the work in the reconstruction of the areas destroyed by the war in Ukraine. In 1950, he achieved the position of deputy within the Supreme Soviet of the Soviet Union, the main legislative body of the country. In parallel, he became the first secretary of the party in the Moldova region.
After Stalin's death, with the rise of Nikita Jrushchov, Brézhnev continued his political ascent. He was commissioned by the political direction of the Army and the Navy. In 1955, he obtained the position of Kazakhstan's first secretary, one of the constitutive republics of the Soviet Union. Then, he was appointed full member of the Politburo, the highest governing body of the USSR. In 1960, he achieved the position of President of the Supreme Soviet Presidium.
Between 1962 and 1964, he worked along with other party leaders, at the departure of Jruschev from the USSR government. He got the members of the Politburo to vote for Jruschev's dismissal and appointed him first secretary of the PCUS.
Government of the Soviet Union

When assuming the USSR government, Brézhnev defended what was called a “collective leadership.” He considered, together with the rest of the members who had supported him for the dismissal of Jruschev, that the collective consensus of the party's leaders had to prevail over the individual authority. During the 1960s and 1970s, Brézhnev left many of the main state issues in the hands of Alekséi Kosyguin and Nikolai Podgorni, and concentrated especially on international relations.
Regarding the internal policy of the USSR, the Brézhnev government He developed an increasingly repressive attitude about freedoms and culture. The KGB (government intelligence agency) obtained more and more functions and, by the end of the 1960s, had infiltrated most organizations that opposed the government.
In economic terms, the Brézhnev government was characterized by great economic growth linked to the increase in agricultural production already improvement in industrial productivity. However, this economic boom began to deteriorate in the early 1970s.
In the international field, with Andréi Gromiko at the head of Soviet diplomacy, Brézhnev affirmed the concept that in the West was known as “Brézhnev Doctrine”: He argued that the USSR had the right to military intervention in cases where “the essential interest of other socialist countries were threatened by one of them.” This doctrine was used to justify the invasion of Czechoslovakia by the USSR and the states of the Warsaw Pact in 1968.
On the other hand, taking advantage of the decolonizing process of the Western powers, Brézhnev expanded the Soviet area of influence in Africa and other parts of Asia.
Regarding relations with the United States during the Cold War, the Brézhnev government period coincides with the height of the distension era. Relations with Western Germany in 1970 were normalized, the Cuatripartite Agreement on Berlin was signed in 1971.
In addition, the Salt (1972 and 1979) agreements were achieved and the final act of the Helsinki Conference in 1975 was signed. However, the final period of his government was marked by the return to the tension, from the deployment of the SS-20 in Europe and the invasion of Afghanistan in 1979.
In the early 1980s, Brézhnev began to have serious health problems. During the last years of his government, political decisions remained in the hands of the Politburo and under the influence of some party leaders such as Gromiyko, Ustínov and Andrópov. Leonid Brézhnev died from a heart attack on November 10, 1982.

The Breznev doctrine
It is known as “Brézhnev doctrine” to the international policy that Brézhnev carried out during his government. The leader argued that it was necessary to intervene in the policy of the socialist countries of the East Block when events were presented that endangered the stability of communist regimes.
In that sense, in 1968 Brézhnev directed the invasion of the Troops of the Warsaw Pact to Czechoslovakia, when the local government began to make reforms to release some features of the political, economic and social regime.
For Brézhnev's attitude, the growth of the USSR during his government and the way of publishing his ideas, for many it became evident that the leader defended the supremacy of the Soviet Union in the East Block and believed that the USSR had the right to intervene and, in some cases, direct the internal policy of communist countries.
In retrospect, through this doctrine the action of the USSR and the Warsaw Pact was justified during the insurrection of Berlin (1953) and the Hungarian revolution (1956).
