In 1824, shortly before its merger with West Prussia, the population of East Prussia was 1,080,000 people. Of that number, according to Karl Andree, Germans were slightly more than half, while 280,000 (~26%) were ethnically Polish and 200,000 (~19%) were ethnically Lithuanian. As of 1819, there were also 20,000 ethnic Curonian and Latvian minorities as well as 2,400 Jews, according to Georg Hassel. Similar numbers are given by August von Haxthausen in his 1839 book, with a breakdown by county. However, the majority of East Prussian Polish and Lithuanian inhabitants were Lutherans, not Roman Catholics like their ethnic kinsmen across the border in the Russian Empire. Only in Southern Warmia (German: Ermland) Catholic Poles – so called Warmiaks (not to be confused with predominantly Protestant Masurians) – comprised the majority of population, numbering 26,067 people (~81%) in county Allenstein (Polish: Olsztyn) in 1837. Another minority in East Prussia, were ethnically Russian Old Believers, also known as Philipponnen – their main town was Eckersdorf (Wojnowo).
