minorities (see Table 1. below). Before the Second World War, Silesia was inhabited mostly by Germans, with Poles a large minority, forming a majority in Upper Silesia. Silesia was also the home of Czech and Jewish minorities. The German population tended to be based in the urban centres and in the rural areas to the north and west, whilst the Polish population was mostly rural and could be found in the east and in the south. Ethnic structure of Prussian Upper Silesia (Opole regency) during the 19th century and the early 20th century can be found in Table 2.: The Austrian part of Silesia had a mixed German, Polish and Czech population, with Polish-speakers forming a majority in Cieszyn Silesia. Religion Historically, Silesia was about equally split between Protestants (overwhelmingly Lutherans) and Roman Catholics. In an 1890 census taken in the German part, Roman Catholics made up a slight majority of 53%, while the remaining 47% were almost entirely Lutheran. Geographically speaking, Lower Silesia was mostly Lutheran except for the Glatzer Land (now Kłodzko County). Upper Silesia was mostly Roman Catholic except for some of its northwestern parts, which were predominantly Lutheran. Generally speaking, the population was mostly Protestant in the western parts, and it tended to be more Roman Catholic the further east one went. In Upper Silesia, Protestants were concentrated in larger cities and often identified as German. After World War II, the religious demographics changed drastically as Germans, who constituted the bulk of the Protestant population, were forcibly expelled. Poles, who were mostly Roman Catholic, were resettled in their place. Today, Silesia remains predominantly Roman Catholic. Existing since the 12th century, Silesia's Jewish community was concentrated around Wrocław and Upper Silesia, and numbered 48,003 (1.1% of the population) in 1890, decreasing to 44,985 persons (0.9%) by 1910. In Polish East Upper Silesia, the number of Jews was around 90,000–100,000. Historically the community had suffered a number of localised expulsions such as their 1453 expulsion from Wrocław. From 1712 to 1820 a succession of men held the title Chief Rabbi of Silesia ("Landesrabbiner"): Naphtali ha-Kohen (1712–16); Samuel ben Naphtali (1716–22); Ḥayyim Jonah Te'omim (1722–1727); Baruch b. Reuben Gomperz (1733–54); Joseph Jonas Fränkel (1754–93); Jeremiah Löw Berliner (1793–99); Lewin Saul Fränkel (1800–7); Aaron Karfunkel (1807–16); and Abraham ben Gedaliah Tiktin (1816–20).
