Established on 4 April 1892 by Queen Regent Emma acting for Queen Wilhelmina, the Orde van Oranje-Nassau recognizes those with special merits for society. The military division, denoted by crossed swords, honors military personnel for notable service. The rank of Ridder (Knight) is conferred for significant contributions. During World War II, it was awarded to individuals who assisted in the liberation of the Netherlands. The order includes six grades, and recipients are typically announced on the Monarch's official birthday. In the Netherlands, titles or post-nominals are generally not used.
