meetings in Berlin in 1927 and Prague in 1928, at the founding congress in Vienna in 1929 the veterans of the UVO and the student militants met and united to form the Organization of Ukrainian Nationalists (OUN). Although the members consisted mostly of Galician youths, Yevhen Konovalets served as its first leader and its leadership council, the Provid, comprised mostly veterans and was based abroad. Pre-war activities Prior to World War II, the OUN was smaller and less influential among the Ukrainians minority in Poland than the moderate UNDO party. OUN ideology was influenced by political theorists such as Dmytro Dontsov, whose political thought was characterised by totalitarianism, national chauvinism and antisemitism, Mykola Stsiborskyi and as well as Italian fascism and German Nazism. OUN nationalists were trained by Mussolini in Sicily jointly with the Ustase, they also maintained offices in Berlin and Vienna. Before the war, the OUN regarded the Second Polish Republic as an immediate target, but viewed the Soviet Union, although not operating on its territory, as the main enemy and greatest oppressor of the Ukrainian people. Even before the war, impressed by the successes of fascism, OUN radicalised its stance, and it saw Nazi Germany as its main ally in the fight for independence. In contrast to UNDO, the OUN accepted violence as a political tool against foreign and domestic enemies of their cause. Most of its activity was directed against Polish politicians and government representatives. Under the command of the Western Ukrainian Territorial Executive (established in February 1929), the OUN carried out hundreds of acts of sabotage in Galicia and Volhynia, including a campaign of arson against Polish landowners (which helped provoke the 1930 Pacification), boycotts of state schools and Polish tobacco and liquor monopolies, dozens of expropriation attacks on government institutions to obtain funds for its activities, and assassinations. From 1921 to 1939 UVO and OUN carried out 63 known assassinations: 36 Ukrainians (among them one communist), 25 Poles, 1 Russian and 1 Jew. This number is likely an underestimate because there were likely unrecorded killings in rural regions. The OUN's victims during this period included Tadeusz Hołówko, a Polish promoter of Ukrainian-Polish compromise, Emilian Czechowski, Lwow's Polish police commissioner, Alexei Mailov, a Soviet consular official killed in retaliation for the Holodomor, and most notably Bronisław Pieracki, the Polish interior minister. The OUN also killed moderate Ukrainian figures such as the respected teacher (and former
