A plebiscite in Saarland shows that 90.3% of those voting wish to no more being a "region occupied and governed by the United Kingdom and France".

A referendum on territorial status was held in the Territory of the Saar Basin on 13 January 1935. Over 90% of voters opted for reunification with Germany, with 9% voting for the status quo as a League of Nations mandate territory and less than 0.5% opting for unification with France.

The Territory of the Saar Basin was a region 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 returned to Germany.
