Royal Hohenzollern House Order, as its name implies, was not so much a Prussian order as an order of the Prussian ruling family, the Hohenzollerns. Nonetheless, this order earned an important place in the heirarchy of Prussian military awards of the First World War. The knight's cross of this order became a bridge to the considerable gap between the Iron Cross, first class, and the Pour le Merite for recognizing heroism., while the Crown Order and Red Eagle (logical choices) remained fairly exclusive.

There was also a "member's cross" of the order which was available to non-commissioned officers, but was rarely awarded. When awarded for duty in a combat unit or for combat operations, the decoration had swords between the arms of the cross. There were over 8,000 awards made during World War I, the vast majority of them knight's crosses.
