Saudi campaign The pretext for renewed hostilities between
Nejd and
Hejaz came when the pilgrims from Nejd were denied access to the holy places in Hejaz. On 29 August 1924,
Ibn Saud began his military campaign against Hejaz by advancing towards
Taif, which surrendered without a major struggle. Following the
fall of Taif, the Saudi forces and the allied Ikhwan tribesmen moved on Mecca. Sharif Hussein's request for British assistance was denied to him on the grounds of non-intervention in religious disputes. King
Hussein bin Ali had meanwhile fled from
Mecca to
Jeddah, after the assistance request from his son,
King Abdullah of Transjordan was denied as well. The city of
Mecca fell without struggle on 13 October 1924. On 16 October 1924, Hussein abdicated as King of the Hejaz and fled the Hejaz, never to return. The Islamic Conference, held in
Riyadh on the 29 October 1924, brought a wide Islamic recognition of Ibn Saud's jurisdiction over
Mecca. By end of October 1924, all the Hashemites held were the port cities of
Jeddah and
Yanbu along with
Medina. The rapid defeat of the Hashemites was due largely to the end of British subsidies. Without the bribes in form of British gold that were paid out to the Bedouin chiefs of the Hejaz, the unpopular regime of Hussein promptly collapsed. The merchants of Yanbu,
Medina and especially Jeddah were determined not to be conquered by Ibn Saud – whom they viewed as a religious fanatic from the Nejd – and collected their wealth together to fund a makeshift army that allowed Yanbu, Medina and Jeddah to hold out against the Saudi forces into 1925. With the advancement of the Saudi forces and blockade imposed on Jeddah, the Hejazi army began to disintegrate. The city of Medina surrendered on 9 December 1925, and Yanbu fell 12 days later. In December 1925
Jeddah was handed to Ibn Saud and Saudi forces entering its gates on 8 January 1926, after capitulation and safe passage was negotiated between
King Ali bin Hussein, Ibn Saud, and the British Consul by the city's ruler Sheikh Abdullah Alireza. ==Aftermath==
