To protect their rights and avoid vassalage to more powerful nobles, they organized themselves into three unions (Partheien) in the late 15th century and into a single body in 1577, and fought to win recognition. However, unlike all of those, the Imperial knights did not possess the status of Estates (Stände) of the Empire, and therefore were not represented, individually or collectively, in the Imperial Diet. What distinguished them from other knights, who were vassals of a higher lord, was the fact that they had been granted Imperial immediacy, and as such were the equals in most respects to the other individuals or entities, such as the secular and ecclesiastical territorial rulers of the Empire (margraves, dukes, princes, counts, archbishops, bishops, abbots, etc.) and the Free Imperial cities, that also enjoyed Imperial immediacy. They were the remnants of the medieval free nobility (edelfrei) and the ministeriales. The Free Imperial knights (German: Reichsritter Latin: Eques imperii) were free nobles of the Holy Roman Empire, whose direct overlord was the Emperor.
