History
The Najd — the name means "highland" — is the plateau at the heart of Arabia, enclosed by the Nafud in the north and the sand belts of the Dahna to the east. For millennia it was a land of Bedouin tribes and small oasis towns. The Hail region's rock carvings record hunters and herders thousands of years ago; the Tayy tribe of the Ha'il mountains produced the pre-Islamic poet Hatim al-Tai, still the Arab byword for generosity; and the old district of al-Yamamah, around today's Riyadh, fought the early Muslims at the Battle of Yamama in 632.
Diriyah, in Wadi Hanifa, was founded in the 15th century, and in 1744 its emir Muhammad ibn Saud allied with the preacher Muhammad ibn Abd al-Wahhab. Their first Saudi state spread across Arabia until an Ottoman-Egyptian army under Ibrahim Pasha besieged and destroyed Diriyah in 1818. The second Saudi state moved its capital to nearby Riyadh, but in 1891 it fell to the rival Al Rashid dynasty of Ha'il, rulers of the Jabal Shammar.
In 1902 the young Abdulaziz Ibn Saud retook Riyadh in a night raid on the Masmak fort, then won Qassim from the Rashidis and finally took Ha'il in 1921. Riyadh became the capital of the kingdom proclaimed in 1932, and oil money turned a walled mud town into a sprawling modern city; ministries and embassies moved there from Jeddah, and today it is at the centre of Vision 2030, with Diriyah rebuilt as a heritage showcase.
