The
Mazyadids, named after their ancestor Mazyad al-Shaybani (also
Shaybanids after their original tribe of
Shayban or
Yazidids after Mazyad's son
Yazid), was an Arab family what came to rule over the region of
Shirvan (in
Azerbaijan) in the late 8th century. From 861 on, with
Haytham ibn Khalid's assumption of the ancient Iranian title of
Shirvanshah, they practically broke free of
Abbasid control and ruled Shirvan more or less independently until the 14th century.
