In Yemen, popular committees are armed groups formed by Yemeni tribes on behalf of more professional military forces.
The Yemeni army has required the support of tribal militias or what have become known as People's Committees in internal and external wars. When the 1963 revolution in northern Yemen did not receive military support from the United Kingdom, some troops allied with the deposed imams to regain power. Tribal links weakened, especially in Taiz and Ibb; members received a monthly salary, wore military uniforms and underwent military training.
During the presidency of Abdul Rahman al-Iryani (1967–1974) the military battled over policy, beginning with a conflict over the establishment of the National Council. The popular committees further polarized the country.
