The Republic of Uzbekistan is a presidential constitutional republic, whereby the President of Uzbekistan is head of state. Executive power is exercised by the government and by the Prime Minister of Uzbekistan. Legislative power is vested in the two chambers of the Oliy Majlis, the Senate and the Legislative Chamber.

The movement toward economic reform in Uzbekistan has not been matched by a movement toward political reform. The government of Uzbekistan has instead tightened its grip since independence (September 1, 1991), cracking down increasingly on opposition groups.

The Communist Party of the Soviet Union (CPSU) occupied the central position in ruling the country. The party provided both the guidance and the personnel for the government structure. The system was strictly bureaucratic: every level of government and every governmental body found its mirror image in the party. The instrument used by the CPSU to control the bureaucracy was the system of nomenklatura, a list of sensitive jobs in the government and other important organizations that could be filled only with party approval. The nomenklatura defined the Soviet political leadership, and the people on the list invariably were members of the CPSU. Following the failure of the coup against the government of Mikhail Gorbachev in Moscow in August 1991, Uzbekistan's Supreme
