The largest metropolis in Galicia was known to its Austrian rulers as Lemberg. The Poles, who dominated the city after 1867, referred to it as Lwόw, while the Ukrainian minority called it L'viv. German, Polish, and Ukrainian-speaking inhabitants constituted the officially recognized national groups, but there also existed a large Jewish element, which in 1900 made up approximately 30 percent of the population. Appearing in Austrian and Polish statistics only as adherents of the Mosaic faith, the Jews differed from their neighbors in far more than religion. Though formally emancipated in 1868, Galician Jewry resembled in all other respects that of Russia. The combination of a very large Jewish minority and a very backward social and economic structure, in Galicia as in the Pale of Settlement, placed great obstacles in the path of cultural assimilation.
