Saada, a city and ancient capital in the northwest of Yemen, is the capital and largest city of the governorate of the same name, and the seat of the eponymous district. The city is located in the mountains of Serat (Sarawat) at an altitude of about 1,800 meters. In 2004, it was the tenth-largest city in Yemen and had an estimated population of 51,870.

The Imams of Yemen, later also titled the Kings of Yemen, were religiously consecrated leaders (imams) belonging to the Zaidiyyah branch of Shia Islam. They established a blend of religious and temporal-political rule in parts of Yemen from 897. Their imamate endured under varying circumstances until the end of the North Yemen Civil War in 1970, following the republican revolution in 1962. Zaidiyyah theology differs from Isma'ilism and Twelver Shi’ism by stressing the presence of an active and visible imam as leader. The imam was expected to be knowledgeable in religious scholarship, and to prove himself a worthy headman of the community, even in battle if this was necessary. A claimant of the imamate would proclaim a "call" (dawah), and there were not infrequently more than one claimant.
