Kaiser Wilhelm was a cousin of Dutch queen Wilhelmina. At the end of WW1 he was in Belgium when a warrant for his arrest was issued. He then fled to the Netherlands, which was neutral during the war. In the Netherlands he applied for asylum, which was quickly granted due to his cousin’s influence with the government. He then lived the rest of his life in the Netherlands, even proposing to Hitler to act as ruler of the Netherlands on Hitler’s behalf.
