The Province of Upper Silesia, which was partially located within modern borders of the Silesian Voivodeship, adopted its flag in 1920. It was rectangle divided horizontally into two stripes: yellow on top, and dark blue on the bottom. The aspect ratio of its height to its width was equal 2:3. Its colours had been based on the coat of arms of Upper Silesia. It was used until 1935, when Nazi Germany forbid its provinces from flying its flags, ordering them to replace them with the national flag. The Opole Voivodeship was established in 1999. Its flag was approved by Opole Regional Assembly on 28 September 2004, and officially adopted on 21 December of the same year. It was designed by Michał Marciniak-Kożuchowski. References
