Knez John

John held a kenazate which was given to the knights by the king. His kenazate lay in southern Oltenia.

The diploma of Béla IV also refers to the kenazates of Farcaş and voivode Litovoi and to voivode Seneslau. Seneslau and Litovoi are expressly said to be Vlachs (Olati) in the king's diploma.

The Romanian historian Ioan-Aurel Pop suggests that the kenazate of John was one of the incipient Romanian states south of the Carpathian Mountains. In the diploma, his name is given in its Latin form (Johannes), and so contains no hint of the nationality of its bearer.
