“We’re not German; We’re not Polish; We’re Silesian. This is a common refrain from members of the Silesian minority in the industrial region of Upper Silesia in southern Poland. With a population of around 2,000,000, the Upper Silesian Metropolitan Union (GZM), whose largest city is Katowice, is one of the biggest urban agglomerations in Europe. For many years, this densely populated region straddled the border between Germany and Poland, with Katowice (Kattowitz) part of the German Empire and neighbouring Sosnowiec part of Congress Poland.” World Soccer
