Dutch Nazi Party Flag. It is in excellent condition and was liberated in 1945 in Amsterdam, Holland. The flag is described as having a black upper half, red lower half with a triangle in centre with design. National Socialist Movement in the Netherlands (Netherlands) Nationaal-Socialistische Beweging in Nederland (NSB) The Nationaal-Socialistische Beweging in Nederland (NSB) was a Dutch fascist and later national socialist political party. In 1941, it absorbed the other Dutch Nazi parties (like the NSNAP) and became the only one. The NSB wanted to unite the Netherlands and Flanders into a single German controlled country called "Dietsland." The NSB was the only legal party in the Netherlands during most of the Second World War. The founder and leader of the "National Socialist Movement in the Netherlands" was Anton Mussert. The party based its program on Italian fascism and German National Socialism, however unlike the latter before 1936 the party was not anti-semitic and even had Jewish members. Beginning in the summer of 1943, many male members of the NSB were organized in the Landwacht, which helped the government control the population. In September of 1944, most of the NSB's leadership fled to Germany and the party's organization fell apart. After the German signing of surrender in 1945, the NSB was outlawed and many members of the NSB were arrested and convicted, including Mussert, who was executed in 1946. After the NSB was founded in 1931, one of their flags used the colors of the Dutch tricolor (the field was orange, with on a white disc and the blue rune sign of the wolfsangel [wolf hook] centered on it), and the other was a black-red horizontal bicolor charged with a triangular-shaped emblem featuring a red-white-blue shield with the Lion of Flanders centered upon it and surrounded by the party initials of "NSB."
