By mid-1941, the [[Ukrainian SSR]] had the largest population of Jews in Europe. The addition of the eastern provinces of [[Poland]] (''the Kresy'') as a result of the [[Molotov-Ribbentrop pact]] in late 1939 ([[Western Ukraine]] after 1945), as well as the seizure of sections of [[Romanian]] territory in June 1940, led to some 2.7 million Jews living within the borders of the newly enlarged republic. About 85% lived in cities. | By mid-1941, the [[Ukrainian SSR]] had the largest population of Jews in Europe.
