The Houthi movement (/ˈhuːθi/; Arabic: الحوثيون al-Ḥūthiyūn [al.ħuː.θi.juːn]), officially known as Ansar Allah[a] (أنصار الله ʾAnṣār Allāh, lit. 'Supporters of God'), is a Shia Islamist political and military organization that emerged from Yemen in the 1990s. It is predominantly made up of Zaidi Shias, with their namesake leadership being drawn largely from the Houthi tribe.
