The Saudi conquest of Hejaz or the Second Saudi-Hashemite War, also known as the Hejaz-Nejd War, was a campaign engaged by Saudi Sultan Abdulaziz to take over the Hashemite Kingdom of Hejaz in 1924–25, ending with conquest and incorporation of Hejaz into the Saudi domain.
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, Abdulaziz 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 pretext 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. The Islamic Conference, held in Riyadh on the 29 October 1924, brought a wide Islamic recognition of Ibn-Saud's jurisdiction over Mecca.
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,[a] and Yanbu fell 12 days later. In December 1925 Jeddah was handed to Abdulaziz of Nejd and Saudi forces entering its gates on 8 January 1926, after capitulation and safe passage was negotiated between King bin Ali, Abdulaziz, and the British Consul by the city's ruler Sheikh Abdullah Alireza.
Following the successful takeover over the Kingdom of Hejaz, Abdulaziz was proclaimed King of Hejaz. The Kingdom was later incorporated into the Kingdom of Nejd and Hejaz with Abdulaziz being the king of both in political union.
After stepping down as king, Hussein of Hejaz moved to Aqaba to support his son's war efforts, which made the British force him into exile to Cyprus. Ali bin Hussein, as the King of Hejaz, took office in the middle of a losing war. With the fall of the Kingdom, the dynasty ended up in exile. Hashemites however remained to rule the Emirate of Transjordan and the Kingdom of Iraq.
