The Hejaz is a region in the west of Saudi Arabia. It includes the cities of Mecca, Medina, Jeddah, Tabuk, Yanbu and Taif. It is also known as the "Western Province" in Saudi Arabia. It is bordered in the west by the Red Sea, in the north by Jordan, in the east by the Najd, and in the south by the Asir Region. The Hejaz is significant for being the location of the Islamic holy cities of Mecca and Medina, the first and second holiest sites in Islam, respectively. As the site of the two holiest sites in Islam, the Hejaz has significance in the Arab and Islamic historical and political landscape. The Ottoman Empire held partial control over the area; after its dissolution, an independent Kingdom of Hejaz existed briefly in 1925 before being conquered by the neighboring Sultanate of Nejd, creating the Kingdom of Hejaz and Nejd. In September 1932, the Kingdom of Hejaz and Nejd joined the Saudi dominions of Al-Hasa and Qatif, creating the unified Kingdom of Saudi Arabia.
