Islam’s birthplace became a kingdom only in 1932
Modern Saudi Arabia unites Hejaz, Najd, Al-Ahsa, and Asir. Ibn Saud took Riyadh in 1902 and proclaimed the kingdom in 1932. Oil struck on 3 March 1938 turned desert provinces into a global energy pivot, while Mecca and Medina remained Islam’s twin sanctuaries.
Prehistory runs deep: stone tools and fauna at Ti’s al Ghadah may mark hominin passage through a greener Arabia 300,000–500,000 years ago; An Nasim in Hail holds Acheulean artifacts about 350,000 years old. Settled cultures included Dilmun in the east, Thamūd north of Hejaz, Kinda in the center, and Al-Magar in the southwest. Lihyan flourished at Dedan between the sixth and second centuries BCE; Nabataeans held Hegra until Rome annexed their realm in 106 CE. Pre-Islamic religion mixed polytheism around Hubal and the goddesses al-Uzza, al-Lat, and Manat, with the Kaaba already a multi-tribal sanctuary; Jewish and Christian communities lived in oases such as Yathrib, Khaybar, and Najran.
Muhammad, born in Mecca about 570, began preaching in 610 and migrated to Medina in 622, uniting Arabian tribes under Islam. After his death in 632 the Rashidun caliphs, then Umayyads from 661, drove conquests from Iberia to India within decades; Abbasids followed from 750. Political power shifted outward, yet Mecca and Medina stayed spiritual centers through the Hajj. After Umayyad collapse much of the peninsula reverted to tribal emirates.
The Al Saud dynasty emerged in central Arabia in 1727 with the Emirate of Diriyah. Abdulaziz ruled successive emirates and the Kingdom of Hejaz and Nejd before becoming king of Saudi Arabia (1932–1953). Later reigns of Saud, Faisal, Khalid, Fahd, Abdullah, and Salman tracked oil wealth, the 1973 oil crisis, the 1979 Grand Mosque seizure, Gulf War alliances, and contemporary reforms under crown prince Mohammed bin Salman.
