Nöker (military)
Nöker was a group of military comrades in the medieval Mongolian and Turkic armies. The word nöker means "comrade" in Mongol Langıage.
The nökers were led by a leader and they were loyal to their leader. These relationships lasted for life. In turn, the leader was responsible for maintaining the wealth of the nökers. According to historian Halil İnalcık, the nöker was comparable to commendatio or homage of the medieval armies in Europe.
