Rawwadid or Ravvadid (also Revend or Revendi) (955–1071), was a Kurdish principality ruling Iranian Azerbaijan from the 10th to the early 11th centuries, centered on Tabriz and Maragheh. According to Minorsky and Bosworth, the Rawadids were originally of Arabic ancestry, and arrived in the region in the mid eighth century, but they had become Kurdicized by the early 10th century and began to use Kurdish forms like Mamlan for Muhammad and Ahmadil for Ahmad as their names
