Opole (; ) is a city in southern Poland on the Oder River (Odra). It has a population of 129,553 and is the capital of the Opole Voivodship. It is the historical capital of Upper Silesia. Today, many Poles of German ancestry live in the Opole region.
While German merchants had earlier established a colony in Opole at the crossing of the Oder, German peasants began arriving in 1217. Opole received German town law in 1254, which was expanded with Środa Śląska law in 1327 and Magdeburg rights in 1410. Along with most of Silesia, in 1327 the Duchy of Opole came under the sovereignty of the Kingdom of Bohemia, itself part of the Holy Roman Empire. In 1521 the Duchy of Racibórz (Ratibor) was inherited by the Duchy of Opole, by then also known by the German name Oppeln. With the death of King Louis II of Bohemia at the Battle of Mohács, Silesia was inherited by Ferdinand I, placing Oppeln under the sovereignty of the Germanizing Habsburg Monarchy of Austria. The Habsburgs took control of the region in 1532 after the line of local Piast dukes died out. Beginning in 1532 the Habsburgs pawned the duchy to different rulers (see Dukes of Opole). With the abdication of King John II Casimir of Poland as the last Duke of Opole in 1668, the region passed to the direct control of the Habsburgs.
King Frederick II of Prussia conquered most of Silesia from Austria in 1740 during the Silesian Wars; Prussian control was confirmed in the Peace of Breslau in 1742. From 1816-1945 Opole was the capital of Regierungsbezirk Oppeln within Prussia. The city became part of the German Empire during the unification of Germany in 1871. After the defeat of Imperial Germany in World War I, a plebiscite was held on March 20 1921 in Opole to determine if the city would be in the Weimar Republic or become part of the Second Polish Republic. 20,816 (94.7%) votes were cast for Germany, 1,098 (5.0%) for Poland, and 70 (0.3%) votes were declared invalid. Voter participation was 95.9%. Eastern Upper Silesia, including the industrial region of Katowice, was granted to Poland in 1922.
Opole was the administrative seat of the Province of Upper Silesia from 1919-1939. With the defeat of Poland in the Polish September Campaign at the beginning of World War II in 1939, eastern Upper Silesia was readded to the Province of Upper Silesa and Opole lost its status as provincial capital to Katowice.
After the end of the Second World War in 1945, Oppeln was transferred from Germany to Poland according to the Potsdam Conference, and given its old Slavic name of Opole. Opole became part of the Katowice Voivodship from 1946-1950, after which it became part of the Opole Voivodship. Unlike other parts of historical eastern Germany ceded to remapped Poland, Opole and the surrounding region's German population remained and was not forcibly expelled, even though many left to West Germany to flee the Eastern Bloc. Today Opole, along with the surrounding region, is known as a centre of the German-speaking Silesian minority in Poland.
Opole hosts the annual National Festival of Polish Songs. The city is also known for its 10th century Church of St. Adalbert and the 14th century Church of the Holy Cross.
