He continued his secondary education at matriculation courses in Prague at the Ukrainian Economic Academy.

During the Second World War, he lived for some time in Warsaw, and in 1942 moved to Kyiv to establish political work there.

As president of the UPR, he proved himself to be more of an authoritarian figure, which provoked a conflict between the parties that were part of the UNR Rada in the 1970s.

The conflict was resolved after the adoption of the Temporary Law, which somewhat democratized the State Center of the UPR in exile.

He wrote a number of works, including “West - East and the Problem of Nations Enslaved by Moscow” (1975), “The State Center of the UPR in Exile between 1920 and 1940” (1984).
