The Houthi insurgency in Yemen
, also known as the Houthi rebellion
, Sa'dah War
, or Sa'dah conflict
, was a military rebellion pitting Zaidi Shia Houthis against the Yemeni military that began in Northern Yemen and has since escalated into a full-scale civil war. The conflict was sparked in 2004 by the government's attempt to arrest Hussein Badreddin al-Houthi, a Zaidi religious leader of the Houthis and a former parliamentarian on whose head the government had placed a $55,000 bounty. Initially, most of the fighting took place in Sa'dah Governorate in northwestern Yemen, but some of the fighting spread to neighbouring governorates Hajjah, 'Amran, al-Jawf and the Saudi province of Jizan. Since 2014 the nature of the insurgency has changed with the Houthi takeover in Yemen and then into the ongoing Yemeni civil war (2015–present) with a major Saudi-led intervention in Yemen beginning in 2015.
