Al-Mansur Muhammad Hamid al-Din, who was in San’a’ at the time, was called on to take the Imamate and had little option but to leave he city. The sayyids of the Sa’dah area took time to organize themselves around him (al-Mahdi Muhammad was still active at Barat), and meanwhile some hundreds of Hashid chiefs came into San’a’, returning still in receipt of large Turkish stipends (al-Hibshi 1980: 393-9). But the rains then failed, and fighting broke out between the tribes just north-east of San’a’. The sorghum crop was ruined in the summer by locusts and the Turks applied severe pressure to the shaykhs of Hajjah, among other areas, presumably to extract taxes […].’ §REF§Dresch, Paul  1989. “Tribes, Government, and History in Yemen”, 220§REF§ ‘In the west the Imam suffered further setbacks. From the start of the rising certain northern shaykhs were conspicuous in the area, probably fighting around their own landholdings: Nasir Mabkhut al-Ahmar of al-‘Usaymat and Muhsin al-Qayifi of Kharif around Mahwit […]. Zafir Hajjah was finally surrendered after having been held by the Imam’s supporters for a full year. Nasir al-Ahmar admitted that although the water tanks were running dry and his men were exhausted, the surrender itself involved ‘a sum of money’ (shay’ min al-mal).  ‘Ali al-Iryani reckoned it at 11,000 riyals (Zabarah 1956:i. 2/81-2), an enormous sum by the standards of the time.’ §REF§Dresch, Paul  1989. “Tribes, Government, and History in Yemen”, 221§REF§ No banking systems or other forms of credit structures are mentioned for the Ottoman period."
