More than 270 out of 450 members of the Verkhovna Rada voted in favor of the bill. No one voted against it.
Organizations covered by the controversial legislation include the Ukrainian Insurgent Army (UPA) and the Organization of Ukrainian Nationalists (OUN).
These so-called freedom fighters, in reality radical right-wing groups or revolutionary ultranationalists, have a dark past. The Ukrainian Insurgent Army is a vivid example.
The UPA was established as the armed wing of the Ukrainian nationalists in 1942. The UPA operated mainly in western Ukraine, fighting against Soviet forces on the side of Nazi Germany. In 1943, the UPA massacred as many as 100,000 Polish civilians in Volhynia and Eastern Galicia.
To see the flag of the Ukrainian Insurgent Army in London is hideous. Jews/Russians/Poles were murdered in their thousands under that flag.— Marcus Papadopoulos (@DrMarcusP) 15 Март 2015
After the end of World War II, the UPA continued to fight against the Soviet Union using radical means, including terrorism and violence. The UPA committed countless atrocities, targeting intellectuals and local authorities.

War veterans and politicians have sharply criticized the glorification of the UPA and its leaders, Stepan Bandera and Roman Shukhevych, accusing them of collaborating with the Nazis.
Stepan Bandera’s Organization of Ukrainian Nationalists encouraged locals to ‘destroy’ Jews and Poles in the 1940s http://t.co/4Xw7STy2yQ— Christoph Heer (@ChristophHeer52) 24 Март 2015
In November 2014, Russia's Supreme Court branded the Ukrainian Insurgent Army a terrorist organization, banning its activity in the country.
