Territory of the Saar Basin
In 1933, many anti-Nazi Germans fled to the Saar, as it was the only part of Germany left outside the Third Reich's control.  As a result, anti-Nazi groups wanted the Saarland to remain under control of League of Nations as long as Adolf Hitler ruled Germany.  However, France had a lot of power in the Saar, including control of the coal mines.  Not many Saarlanders liked France, and in the plebiscite on 13 January 1935, 90% of the voters wished to join Germany, and 8.86% wanted to stay with the League of Nations.  Only 0.40% (that is, four voters in every thousand) wanted to join France.
