France was one of the largest military powers to come under occupation as part of the Western Front in World War II.

The Western Front was a military theatre of World War II encompassing Denmark, Norway, Luxembourg, Belgium, the Netherlands, the United Kingdom, France, Italy, and Germany.

The Western Front was marked by two phases of large-scale combat operations.

The first phase saw the capitulation of the Netherlands, Belgium, and France during May and June 1940 after their defeat in the Low Countries and the northern half of France, and continued into an air war between Germany and Britain that climaxed with the Battle of Britain.

France was not liberated until 1944, when the allied invasion restored the French Government.
