The siege of Dammaj began in October 2011 when the Houthis, a Zaydi-led rebel group which controls the Sa'dah Governorate, accused Salafis loyal to the Yemeni government of smuggling weapons into their religious center in the town of Dammaj and demanded they hand over their weapons and military posts in the town. As the Salafis refused, Houthi rebels responded by imposing a siege on Dammaj, closing the main entrances leading to the town. The town was controlled by the Houthis and the fighting was mainly centered at Dar al-Hadith religious school, which was operated by Salafis.

It had origins in Houthi-led protests that began the previous month, and escalated when the Houthis stormed the Yemeni capital Sanaa on 21 September 2014, causing the resignation of Prime Minister Mohammed Basindawa, and later the resignation of President Abdrabbuh Mansur Hadi and his ministers on 22 January 2015 after Houthi forces seized the presidential palace, residence, and key military installations, and the formation of a ruling council by Houthi militants on 6 February 2015.
