Corruption is an issue in Ukrainian society going back to the dissolution of the Soviet Union in 1991. After declaring independence from the Soviet Union, Ukraine faced a series of politicians from different sides of the political spectrum, as well as criminal bosses and oligarchs, who used the corruption of police, political parties, and industry to gain power. Despite improvements, as in Moldova corruption remains an obstacle to joining the EU.
