Territory of the Saar Basin

The Territory of the Saar Basin was a region of Germany occupied and governed by the United Kingdom and France from 1920 to 1935 under a League of Nations mandate. It had its own flag : a blue, white, and black horizontal tricolour. The blue and white stood for Bavaria, and white and black for Prussia, out of whose lands the Saar Territory was formed. Initially, the occupation was under the auspices of the Treaty of Versailles. Its population in 1933 was 812,000, and its capital was Saarbrücken. The territory closely corresponds with the modern German state of Saarland, but was slightly smaller in area. After a plebiscite was held in 1935, it was restored to Germany.
Under the Treaty of Versailles, the highly industrialized Saar Basin, including the Saar Coal District , was to be occupied and governed by the United Kingdom and France under a League of Nations mandate for a period of fifteen years. Its coalfields were also to be ceded to France. During this time, the Saar Territory was governed by the five-person Governing Commission made up of representatives of the occupation forces. Under the terms of the mandate, the Commission had to include at least one French person and one German resident of the Saar. After that time, a plebiscite would be implemented to determine the Saar's future status.
