A royal charter dated 18 June 1325 records that a person named Stephen, who was the son of a Cuman ispán in Hungary, stated that the king was weaker than Basarab and "did not even reach up to [his] ankle". The same charter describes Basarab as "disloyal to the Holy Crown of Hungary", showing that Basarab had betrayed the crown. A royal charter from 1329 listed Basarab, along with the Bulgarians, Serbs and Tatars, as an enemy who "[made] hostile inroads" around Mehadia. Basarab seems to have entirely controlled the Banate of Severin between 1324 and 1330, since royal charters did not mention a Ban of Severin during this period. In a letter written in 1327, Pope John XXII alluded to "territories of the Kingdom of Hungary which were subjected" to Basarab.
