Perestroika ( PERR-ə-STROY-kə; Russian: перестройка, romanized: perestroyka, IPA: [pʲɪrʲɪˈstrojkə] ) was a political reform movement within the Communist Party of the Soviet Union (CPSU) during the late 1980s, widely associated with CPSU general secretary Mikhail Gorbachev and his glasnost (meaning "transparency") policy reform. The literal meaning of perestroika is "restructuring", referring to the restructuring of the political economy of the Soviet Union in an attempt to end the Era of Stagnation.
Perestroika allowed more independent actions from various ministries and introduced many market-like reforms. The purported goal of perestroika was not to end the planned economy, but rather to make socialism work more efficiently to better meet the needs of Soviet citizens by adopting elements of liberal economics. The process of implementing perestroika added to existing shortage and created political, social, and economic tensions within the Soviet Union. Furthermore, it is often blamed for the political ascent of nationalism and nationalist political parties in the constituent republics.
