The organization of Ukrainian nationalists is revolutionary
The Revolutionary Organization of Ukrainian Nationalists (OUNR, OUN (r); also - OUN (b) , preservation and development of it and the Ukrainian Nation. The OUNR was formed in February 1940 as a result of the departure of Stepan Bandera from the OUN.
Most Ukrainian researchers believe that the reason for the future split of the OUN into Bandera and Melnyk was the dissatisfaction of the "Krai" with the emigrant leadership of the OUN. Frictions between emigration and the Krai had arisen before, but then the authority of OUN leader Yevhen Konovalets prevented the split, and Andriy Melnyk, who replaced Konovalets as head of the PUN, did not have such authority in the eyes of Galicians. Since the 1930s, since the sabotage operation, the National Leadership has been a little more radical about terrorism against Poland. It is this position of the radical Krai that has put the OUN on the path to terror. It is known that Konovalets opposed individual terror as a method of political struggle in Western Ukraine, but he did not hinder the activities of terrorists and defended their position before the less radical members of the leadership.
The assassination of Yevhen Konovalets and the inauguration of OUN leader Melnyk, who did not take an active part in the organization's activities during the 1930s, exacerbated the friction. The situation around Carpathian Ukraine in 1938-1939 and the PUN's position on the policy of Ukrainian nationalists and their participation in the life of Carpathian Ukraine deepened the accumulated contradictions. Even before the legalization of the autonomy of Subcarpathian Russia in October 1938, many OUN volunteers from Galicia and Volhynia, contrary to Melnyk's instructions, illegally crossed the Polish-Czechoslovak border and participated in the creation of a local militia - the organization "Carpathian Sich", among them the future commander-in-chief of the Ukrainian Insurgent Army Roman Shukhevych, but soon the PUN forbade its members to cross the Polish-Czechoslovak border without the permission of the Provod, and the PUN representative in Transcarpathia Yaroslav Baran
