The region that was occupied by the Germans during both World War I and World War II but is currently part of France is Alsace-Lorraine. This area was annexed by Germany after the Franco-Prussian War in 1871 and remained under German control until the end of World War I in 1918. It was reannexed by Germany during World War II, but after the war, it was returned to France. Today, Alsace is known for its distinct culture and history, reflecting both French and German influences.
