Plebiscite in Upper Silesia

The Plebiscite in Upper Silesia was a vote held in 1921 to determine whether the region should be part of Germany or Poland. After World War I, the area, which had a mixed population of Germans and Poles, was contested. To resolve this, a referendum was organized, allowing residents to choose their national affiliation. The vote resulted mainly in favor of joining Poland, but parts remained under German control. This plebiscite aimed to address local preferences peacefully and define borders based on the people's will, contributing to the region's complex post-war territorial adjustments.
