What was the primary purpose of the Saar plebiscite held in 1935?

The primary purpose of the Saar plebiscite held in 1935 was to determine the region's future governance. The Saar region had been under the administration of the League of Nations since the end of World War I as a consequence of the Treaty of Versailles, which aimed to manage territorial disputes and ensure peace. The plebiscite allowed the people living in the Saar to decide whether they wanted to remain under League control, return to Germany, or form an independent state. Ultimately, the vote determined that the Saar would be re-incorporated into Germany, reflecting the wishes of its inhabitants at that time.

This plebiscite was significant not only as an assertion of self-determination but also because it tested the principles of the Treaty of Versailles and the effectiveness of the League of Nations in managing post-war territorial issues.
