Tadeusz Hołówko

He was most notable for his moderate stance on the "Ukrainian problem" faced by the Polish government, which due to its nationalist policies in Poland's largely Ukrainian- and Belarusian-populated eastern territories, faced increasing tensions there. Despite, or perhaps because of, being a relative moderate in policies toward the Ukrainian population, and a supporter of peaceful cooperation, he was assassinated in 1931 by two members of the radical Organization of Ukrainian Nationalists.
