Umland, Andreas; Anton Shekhovstsov (2013). «Ultraright Party Politics in Post-Soviet Ukraine and the Puzzle of the Electoral Marginalism of Ukraine Ultranationalists in 1994–2009.». Russian Politics and Law51 (5): 33–58. doi:10.2753/rup1061-1940510502. «In 1990, one of the best known nationalist parties—the Ukrainian National Assembly (UNA), headed by Dmytro Korchyns'kyi—was established in Lviv ... . In Ukraine itself, the UNA-UNSD became a media phenomenon, not least thanks to its deliberate provocation aimed at left-wing and pro-Russian forces and its frequent clashes with the police. But the UNA had little political success ... . The second best-known ultraright party to emerge at the beginning of the 1990s was the Congress of Ukrainian Nationalists (CUN)—a direct heir of the Organization of Ukrainian Nationalists (Bandera) (OUN-B), which Stepan Bandera headed in 1940 after a split in the original OUN. The continuity between the OUN-B and the CUN was ensured by the return from abroad of Iaroslava Stets'ko, a former member of the OUN-B and the widow of Iaroslav Stets'ko, one of the leaders of the OUN-B and the Ukrainian Insurgent Army».
