History of Opole

Opole was the administrative seat of the Province of Upper Silesia from 1919–1939. With the defeat of Poland in the Invasion of Poland at the beginning of World War II in 1939, formerly Polish Eastern Upper Silesia was re-added to the Province of Upper Silesia and Opole lost its status as provincial capital to Katowice (renamed Kattowitz).

On 15 February 1941 and 26 February 1941, two deportation transports with 2,003 Jewish men, women and children on board left Vienna Aspang Station for the ghetto which had been set up in Opole. By March 1941, 8,000 Jews were deported to Opole. From May 1941, 800 men capable of work were deployed as forced labourers in Deblin. The "Liquidation" of the Opole ghetto began in the spring 1942. A transport to Belzec extermination camp left on 31 March 1942 and deportations to Sobibor followed in May and October 1942. Of the 2,003 Viennese Jews, only twenty-eight are known to have survived.

In modern Poland

After the end of the Second World War in 1945, Opole was transferred from Germany to Poland according to the Potsdam Conference, and given its original Slavic name of Opole. Opole became part of the Katowice Voivodeship from 1946–1950, after which it became part of the Opole Voivodeship. Unlike other parts of the so-called Recovered Territories, Opole and the surrounding region's autochthon population remained and were not forcibly expelled as elsewhere. Over 1 million Silesians who considered themselves Poles or were treated as such by the authorities due to their language and customs were allowed to stay after they were verified as Poles in a special verification process. It involved declaring Polish nationality and an oath of allegiance to the Polish nation.
