Al-Zayadina (singular: Zaydani or Zidany, also called the Banu Zaydan) were an Arab clan based in the Galilee. They were best known after one of their sheikhs Zahir al-Umar, who, through his tax farms, economic monopolies, popular support, and military strength ruled a semi-autonomous sheikhdom in northern Palestine and adjacent regions in the 18th century.[1]
