The Houthis ( al-Ḥūthiyyūn), officially called Ansar Allah ( "Supporters of God"), is a Zaidi Shia-led movement from Sa'dah, northern Yemen. The group was founded by Hussein Badreddin al-Houthi who started a rebellion in 2004 which led to a Houthi insurgency in Yemen against President Ali Abdullah Saleh. The group has been led by Abdul-Malik al-Houthi since Hussein Badreddin al-Houthi was reportedly killed by Yemeni army forces in 2004.
The Houthis participated in the 2011 Yemeni Revolution as well as the ensuing National Dialogue Conference (NDC). However, they rejected the provisions of the November 2011 Gulf Cooperation Council deal on the ground that "it divided Yemen into poor and wealthy regions" and also in response to assassination of their representative at NDC.
In 2014–2015 Houthis took over the government in Sana'a, which led to the fall of the Saudi Arabian-backed government of Abd Rabbuh Mansur Hadi. Houthis and their allies have gained control of a significant part of Yemen's territory and are currently resisting the Saudi Arabian-led intervention in Yemen seeking to restore Hadi to power. Both the Houthis and the Saudi Arabian-led coalition are being attacked by the Islamic State militant group.
