Klymiv was an OUN leader, who, after the split in OUN in 1939, joined the Bandera faction. Klymiv was arrested in 1935 by the Polish authorities for his role in OUN activities in Halychyna. He was sentenced to ten years in a Polish concentration camp. He was released, along with Bandera and other leaders, after the fall of Poland in 1939.

After the German invasion of the USSR in June 1941 Klymiv headed the territorial executive in Western Ukraine, and after Bandera’s arrest by the German authorities, was a leader in the OUN anti-German underground. Arrested by the Gestapo in 1942, he was tortured to death in December 1942.
