Overview
The statutes of the order were published on 18 January 1701, and revised in 1847. Membership in the Order of the Black Eagle was limited to a small number of knights, and was divided into two classes: members of reigning houses (further divided into members of the House of Hohenzollern and members of other houses, both German and foreign) and capitular knights. Before 1847, membership was limited to nobles, but after that date, capitular knights who were not nobles were raised to the nobility (Adelstand). Capitular knights were generally high-ranking government officials or military officers.
The Order of the Black Eagle had only one class, but could also be awarded at the king's prerogative "with the Chain" ("mit der Kette") or without ("ohne Kette"). By statute, members of the order also held the Grand Cross of the Order of the Red Eagle, and wore the badge of that order from a ribbon around the neck. From 1862, members of the Prussian royal house, upon award of the Order of the Black Eagle, also received the Prussian Crown Order 1st Class.
