While about two-thirds of the city's inhabitants were Poles, some of whom spoke the characteristic Lwów dialect, the eastern part of the Lwów Voivodeship had a relative Ukrainian majority in most of its rural areas. Although Polish authorities obliged themselves internationally to provide Eastern Galicia with an autonomy (including a creation of a separate Ukrainian university in Lwów) and even though in September 1922 adequate Polish Sejm's Bill was enacted, it was not fulfilled. The Polish government discontinued many Ukrainian schools which functioned during the Austrian rule, and closed down Ukrainian departments at the University of Lwów with the exception of one. Prewar Lwów also had a large and thriving Jewish community, which constituted about a quarter of the population.
