On August 29, 1931, Vasyl Bilas and Dmytro Danylyshyn, two members of the Organization of Ukrainian Nationalists, assassinated Tadeusz Hołówko, a Polish cabinet minister and known advocate of Polish-Ukrainian rapprochement vacationing in Truskawiec. This caused an increase in Polish-Ukrainian tension, which culminated in the Ukrainian genocide of Poles in 1943.
