The Houthis, officially known as Ansar Allah, is a Zaydi revivalist and Islamist political and military organization that emerged from Yemen in the 1990s. It is predominantly made up of Zaydis, whose namesake leadership is drawn largely from the al-Houthi family. The group has been a central player in Yemen's civil war, drawing widespread international condemnation for its human rights abuses, including targeting civilians and using child soldiers. The movement is designated as a terrorist organization by some countries. The Houthis are backed by Iran, and they are widely considered part of the Iranian-led "Axis of Resistance".
Under the leadership of Zaydi religious leader Hussein al-Houthi, the Houthis emerged as an opposition movement to Yemen president Ali Abdullah Saleh, whom they accused of corruption and being backed by Saudi Arabia and the United States. In 2003, influenced by the Lebanese Shia political and military organization Hezbollah, the Houthis adopted their official slogan against the United States, Israel, and the Jews. Al-Houthi resisted Saleh's order for his arrest, and was afterwards killed by the Yemeni military in Saada in 2004, sparking the Houthi insurgency. Since then, the movement has been mostly led by his brother Abdul-Malik al-Houthi.
