After graduating from the first Józef Pilsudski Gymnasium in Lviv in 1928 successfully, he entered the Faculty of Law of the University of Warsaw. While studying at the University he began to support the idea of the Ukrainian state revival actively. Due to an active communication with D. Dontsov, A. Livytsky, B. Kravtsiv and other participants of the National Liberation Movement, Yu. Kosach was convinced that there was a drastic need to prepare and implement the national revolution. The ideology of the Ukrainian integral nationalism could be traced clearly in the work, written by Yu. Kosach. He tried to implement his own political views into practice by creating the first OUN headquarters in Volyn. Owing to his efforts, the first nationalist underground network was established in Kovel, and later on, in the territory of Volyn Voivodeship Yu. Kosach was persecuted by the Polish police, which forced him to emigrate in 1933. In the future, he didn’t have a direct connection with the nationalist underground, but Volyn leadership that he founded increased in number and took an active part in the National Liberation Movement.
