### Pomeranian duchies

The griffin is a traditional symbol of the West Pomerania, used since 12th century. Between 12th and 13th century, the griffin become the symbol of the House of Griffin, that ruled in that area. Subsequently, the red griffin on the white background had become the symbol of the Duchy of the Pomerania-Stettin. In the 1730s, that design had become the symbol of the entire Western Pomerania. In 1410, during the Battle of Grunwald, the forces of Casimir V, duke of Pomerania-Stettin, used a white banner with a red griffin on it.

### Province of Pomerania

In 1802, the provisional representatives in the Order-in-Council of the Kingdom of Prussia, under the rule of king Frederick William III of Prussia, were ordered to wear blue greatcoats, in addition to theirs mess dress uniforms. To distinguish representatives of different provinces, the collars of the greatcoats were assigned different colours. Originally, the representatives of the Province of Pomerania had white and gold (yellow) collars. In 1813, the representatives of Pomerania were given entirely white collars.
Additionally, the soldieries of the Pomeranian Landwehr formations were given blue uniforms with white collars. Colours of such design became associated with the colours of the province. On 22 October 1882, the blue and white were legally defined as the colours of the province, including the establishment of the flag. It was divided horizontally into two equal stripes: light blue on top, and white on the bottom. Its aspect ratio height to width ratio was equal 2:3. The blue was officially defined as Prussian blue (dark blue), however, it wasn't popular, with usage of light blue being preferred instead. The flag was used until 1935, when Nazi Germany forbid its provinces from using its flags, ordering them to replace them with the national flag.
