The Hashid tribal federation is the second largest (and the strongest) tribal federation in Yemen. Member tribes of the Hashid Confederation are found primarily in the mountains in the North and Northwest of the country. It was headed by Sheikh Abdullah ibn Husayn al-Ahmar until his death on December 29, 2007 and is headed by his son Sadiq since. Sadiq al-Ahmar launched the Hashid insurgency as part of the 2011 Yemeni uprising against President Ali Abdullah Saleh in May 2011, culminating in the Battle of Sana'a.
According to medieval Yemeni genealogies, Hashid and Bakil are the sons of Jashim bin Jubran bin Nawf Bin Tuba'a bin Zayd bin Amro bin Hamdan.
