prejudice against the Ukrainians and desires for economic exploitation of Ukraine precluded cooperation. The interwar Lithuanian government had particularly close ties with the OUN. During World War II Split in the OUN In September 1939 Poland was invaded and split by Germany and the Soviet Union. On 1 November 1939, Polish territories annexed by the Soviet Union (i.e. Volhynia and Eastern Galicia) were incorporated into the Ukrainian Soviet Socialist Republic. Initially, the Soviet occupation of eastern Poland was met with limited support from the ethnic Ukrainian population. Repression was directed mainly against the ethnic Poles, and the Ukrainisation of education, land reform, and other changes were popular among the Ukrainians. The situation changed in the middle of 1940 when collectivisation began and repressions hit the Ukrainian population. There were 2,779 Ukrainians arrested in 1939, 15,024 in 1940 and 5,500 in 1941, until the German invasion of the Soviet Union. The situation for ethnic Ukrainians under German occupation was much better. About 550,000 Ukrainians lived in the General Government in the German-occupied portion of Poland, and they were favoured at the expense of Poles. Approximately 20 thousand Ukrainian activists escaped from the Soviet occupation to Warsaw or Kraków. In late 1939, Nazi Germany accommodated OUN leaders in the city of Kraków, the capital of the General Government and provided a financial support for the OUN. The headquarters of the Ukrainian Central Committee headed by Volodymyr Kubiyovych, the legal representation of the Ukrainian community in the Nazi zone, were also located in Kraków. Despite the differences, the OUN's leader Yevhen Konovalets was able to maintain unity within the organization. Konovalets was assassinated by a Soviet agent, Pavel Sudoplatov, in Rotterdam in May 1938. He was succeeded by Andriy Melnyk, a 48-year-old former colonel in the army of the Ukrainian People's Republic and one of the founders of the UVO. He was chosen to lead the OUN despite not having been involved in activities throughout the 1930s. Melnyk was more friendly to the Church than were any of his associates (the OUN was generally anti-clerical), and had even become the chairman of a Ukrainian Catholic youth organization that was regarded as anti-Nationalist by many OUN members. His choice was seen as an attempt by the leadership to repair ties with the Church and to become more pragmatic and moderate. However, this direction was opposite to the trend within western Ukraine itself. In Kraków
