SUMMARY
The Alliance of Yemeni Tribes (or Tribal Alliance of Yemen) was a formally organised group under the command of Sadiq al-Ahmar, Sheikh of the Hashid tribal confederation. His second-in-command was Saba Aboluhom, the Sheikh of the Bakil tribal confederation. The Hashid and Bakil tribal confederations were two of the largest and most powerful tribal groupings in Yemen. Despite historically being rivals, the confederations united in their opposition to the authoritarian rule of President Ali Abdullah Saleh in response to the mass killing of protesters by the government during the Arab spring in 2011. President Saleh was himself a member of the Hashid, and its tribes had been a pillar of the regime's while they were led by Sadiq al-Ahmar's father, Abdullah Bin Hussein Al-Ahmar, up until 2007.
The Alliance of Yemeni Tribes were close allies of the Free Yemeni Army, commanded by fellow tribesman General Ali Muhsin al-Ahmar, and the Islamist Islah party. They jointly fought in the conflict over government that resulted in the resignation of Saleh. The alliance took on a supportive background role after the resignation of Saleh and the appointment of the government of Abdrabbuh Mansur Hadi, which was largely filled with Islah loyalists. The alliance continued to support the Forces of Hadi (later renamed Forces of the Presidential Leadership Council) after the coup by Ansarallah in 2015.
Alliance of Yemeni Tribes has been involved in the state-based category of UCDP organised violence.
