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.

The Battle of Saada was a military confrontation that erupted in March 2011 between Houthi rebels and tribal forces loyal to Yemeni President Ali Abdullah Saleh in the northern city of Saada. Following days of heavy clashes, the Houthis managed to capture the entire Saada Governorate including its provincial capital and established an independent administration, thereby marking the first such Yemeni governorate to fall out of central government control since the nationwide uprising began in 2011. Saada later becomes known as the Houthi stronghold since its takeover.
