The Flag of the Saar Protectorate was a distinctive banner used during the period when the Saar region, located in western Germany, was under French administration (1920-1935). The flag consisted of three vertical stripes: black, white, and red, symbolizing France, the Saar protectorate, and Germany respectively. This design reflected the unique political status of the region during that time, as it was a territory placed under League of Nations supervision while being economically tied to Germany. The flag's significance lies in its representation of the complex post-World War I geopolitical landscape in Europe.
