Mordvin Tatars

Mordvin Tatars (Мордовские татары, Tartari di Mordua) was a term used to refer to medieval nobility of Volga Tatar, Volga Finnic, and Burtas descent serving Grand Duchy of Moscow.

History
The term was used interchangeably with the term Mordvin princes (Мордовские князья) in 15-16th centuries in official documents of Grand Duchy of Moscow. First the term was applied to pagan princes.

Noble Families
Tümen Princes Kugushevs (ethnic Mishar) and Rasts (ethnic Moksha ) were mentioned as Mordvin princes. The latter also sometimes referred to as Siberian. Possibly Tyumen and Tümen are mixed.

According to Stefan Kuznetsov: "There are 55 princely families of Mordvin and Mordvin-Tatar descent (e.g. Devlet-Kildeyev, Yedelev (Volga Finnic), Yengalychev, Yenikeyev (Mishar clan), Kildyushev, Kugushev, Kudashev, Kulomzin (Volga Finnic, disputable Erzya or Meryan), Maksutov, Tenishev, Chevkin, Chegodayev, Shuguruv, etc. some of them use the princely title, others only consider themselves princes"
