New Westfalen Trust Territory

Germany's defeat in World War I forced it to renounce all her rights over her overseas possessions to the Allied Powers, including therein Neu Westfalen. On the 28th of June, 1919 the Treaty of Versallies gave the mandate for Neu Westfalen to New Holland, whom would oversee its transition into a democratic nation by 1925 - when it was granted independence; but remained in free association with New Holland until 1938. It choose not to join the League of Nations however.

In World War II New Holland troops were sent to Neu Westfalen during the war to ensure that security and order was kept as the the war raged on around them. Neu Westfalen remained neutral in the European war, but there were reports of citizens travelling to Europe during the war to assist the Nazis.
