Serving Tatars

Their own ownership of shares in state land were granted to Russian and Qasim nobles.

They also, with the Cossacks, protected the Eastern borders of Russia, especially in the modern Orenburg Oblast.

Serving Tatars received land, taxation privileges, financial support and food.

After Vasily II the numbers of Tatars entering the nobility of Muscovy rose dramatically.

A modern estimate suggests that one-third of all Russian nobles were of Turkic origins.
