Bezerenbam and Mișelav

Bezerenbam and Mișelav were the Wallachian leaders mentioned in 1241, in the Persian chronicle Jāmiʿ al-Tawārīkh written by Rashid-al-Din Hamadani. They appear in the context of the Mongol invasion of Europe. The former's army was located in Ilaut country, as the chronicle says:
In his work, History of the Romanians, Alexandru D. Xenopol considers that it is possible for Bezerenbam, or Basarab the ban, to be the same person as Litovoi, mentioned in a document from 1247 as ruler of the same land. He considers Bazaram-bam is an ancestor of the Romanian dynasty of Basarab Bogdan Petriceicu Hasdeu also thinks that the leader was "Basarab the ban", a local leader, while Constantin C. Giurescu considers that this name was a distorted form of the title of Ban of Severin.
Neagu Djuvara has considered the possibility that Mișelav was Seneslau, another Wallachian leader contemporary with and neighbouring Litovoi.
