al-Mukarram led an army to Zabid and killed 8,000 of its inhabitants. He later installed the Zurayids to govern Aden. Ahmad al-Mukarram, who had been afflicted with facial paralysis resulting from war injuries, retired in 1087 and handed over power to his wife Arwa al-Sulayhi. Queen Arwa moved the seat of the Sulayhid dynasty from Sana'a to Jibla, a small town in central Yemen near Ibb. Jibla was strategically near the Sulayhid dynasty source of wealth, the agricultural central highlands. It was also within easy reach of the southern portion of the country, especially Aden. She sent Ismaili missionaries to India where a significant Ismaili community was formed that exists to this day. Queen Arwa continued to rule securely until her death in 1138. Arwa al-Sulayhi is still remembered as a great and much loved sovereign, as attested in Yemeni historiography, literature, and popular lore, where she is referred to as Balqis al-sughra , that is "the junior queen of Sheba". Although the Sulayhids were Ismaili, they never tried to impose their beliefs on the public. Shortly after queen Arwa's death, the country was split between five competing petty dynasties along religious lines. The Ayyubid dynasty overthrew the Fatimid caliphate in Egypt. A few years after their rise to power, Saladin dispatched his brother Turan Shah to conquer Yemen in 1174. Zurayid Dynasty Al-Abbas & al-Mas'ūd sons of Karam Al-Yami from the Hamdan tribe started ruling Aden for the Sulayhids, when Al-Abbas died in 1083. His son Zuray, who gave the dynasty its name, proceeded to rule together with his uncle al-Mas'ūd. They took part in the Sulayhid leader al-Mufaddal's campaign against the Najahid capital Zabid and were both killed during the siege (1110). Their respective sons ceased to pay tribute to the Sulayhid queen Arwa al-Sulayhi. They were worsted by a Sulayhid expedition but queen Arwa agreed to reduce the tribute by half, to 50,000 dinars per year. The Zurayids again failed to pay and were once again forced to yield to the might of the Sulayhids, but this time the annual tribute from the incomes of Aden was reduced to 25,000. Later on they ceased to pay even that since Sulayhid power was on the wane. After 1110 the Zurayids thus led a more than 60 years long independent rule in the city, bolstered by the international trade. The chronicles mention luxury goods such as textiles, perfume and
