The Hashid is the second or third largest - after Bakil (Bakkil) and, depending on sources, Madhaj - yet generally recognized as the strongest and most influential tribal confederation in Yemen. According to medieval Yemeni genealogies, Hashid and Bakil were the sons of Jashim bin Jubran bin Nawf Bin Tuba'a bin Zayd bin Amr bin Hamdan. Member tribes of the Hashid Confederation are found primarily in the mountains in the North and Northwest of the country.
