The first five-year plan of the Union of Soviet Socialist Republics (USSR) was a list of economic goals, implemented by Communist Party General Secretary Joseph Stalin, based on his policy of socialism in one country. Leon Trotsky had delivered a joint report to the April Plenum of the Central Committee in 1926 which proposed a program for national industrialisation and the replacement of annual plans with five-year plans. His proposals were rejected by the Central Committee majority which was controlled by the troika and derided by Stalin at the time. Stalin's version of the five-year plan was implemented in 1928 and took effect until 1932.

The Communist Party of the Soviet Union (CPSU), at some points known as the Russian Communist Party, All-Union Communist Party and Bolshevik Party, and sometimes referred to as the Soviet Communist Party (SCP), was the founding and ruling political party of the Soviet Union. The CPSU was the sole governing party of the Soviet Union until 1990 when the Congress of People's Deputies modified Article 6 of the 1977 Soviet Constitution, which had previously granted the CPSU a monopoly over the political system. The party's main ideology was Marxism–Leninism.
