Ancient Arabia and the Caravan Kingdoms
Long before Islam, the Arabian Peninsula was crossed by incense roads that sustained wealthy oasis kingdoms and linked southern Arabia to the Mediterranean and Mesopotamia.
The deserts of Arabia were never empty. From the third millennium BCE the trading culture of Dilmun, centered on the eastern Gulf, connected Mesopotamia with the Indus valley, and Sumerian texts remembered it as a near-paradisal land of prosperity. Across the peninsula, settled communities clustered around oases and wells, while pastoral nomads moved between them.
From the first millennium BCE the overland incense trade became the engine of wealth in the region. Frankincense and myrrh from southern Arabia were carried north by camel caravan along routes that passed through the northwest of the peninsula. The kingdom of Lihyan, centered on Dadan (modern Dedan/AlUla), grew rich on this trade, developing its own script, monumental art, and irrigated agriculture.
By the late first century BCE the Nabataeans, master traders and hydraulic engineers based at Petra, extended their control southward and made Hegra (al-Hijr, also called Madain Salih) their second city. Under King Aretas IV (9 BCE - 40 CE) Hegra flourished, its sandstone cliffs carved with more than a hundred monumental tombs. After Rome annexed the Nabataean kingdom in 106 CE, the caravan cities slowly declined, but they left a vivid archaeological record of pre-Islamic Arabia.
“The desert kingdoms of Arabia grew rich not from the land but from the road, taxing the frankincense that crossed it.”

The Birth of Islam: Muhammad, Mecca and Medina
In the early 7th century the Prophet Muhammad began preaching a strict monotheism in Mecca; his migration to Medina in 622 founded the first Muslim community and reshaped world history.
Muhammad was born in Mecca around 570 CE into the Banu Hashim clan of the dominant Quraysh tribe, in a Hejaz where the Kaaba was already a center of pilgrimage and trade. According to Islamic tradition, at about the age of forty he began to receive revelations through the angel Gabriel in a cave on Mount Hira, calling his people to worship one God and warning of a final judgment.
His message of monotheism and social justice met resistance from the Meccan elite, whose authority and trade were bound up with the existing shrine. After roughly thirteen years of preaching and persecution, in 622 CE Muhammad and his followers migrated to the oasis city of Yathrib, soon renamed Medina. This Hijra became the founding event of the Muslim community and marks year one of the Islamic calendar.
In Medina, Muhammad united the local clans and his followers into a single political and religious community, negotiating an agreement among them. Over the following decade the new faith spread across the Hejaz; Mecca submitted, and by Muhammad's death in 632 CE much of the Arabian Peninsula had embraced Islam. The two cities of Mecca and Medina have remained the holiest sites of Islam ever since, and the land of their origin lies at the spiritual heart of modern Saudi Arabia.
“The migration to Medina in 622 marks not only the start of the Muslim calendar but the birth of a community that would transform Arabia.”

Chapter 03 · 632 - 1744 CE
The Caliphates and the Hejaz under Outside Rule
After Muhammad's death the centers of Islamic power moved away from Arabia, and for more than a thousand years the Hejaz and its holy cities were governed by distant caliphs, local sharifs, and finally the Ottomans.
Under the first caliphs Medina served as the capital of a rapidly expanding empire, but within a generation the political center of Islam shifted outward. The Umayyad caliphs (661-750) ruled from Damascus and the Abbasids (from 750) from Baghdad, governing the Hejaz through appointed governors while lavishing patronage on Mecca and Medina to secure the prestige of the pilgrimage.
From the 10th century onward the holy cities were administered locally by the Sharifate of Mecca, a line of sharifs claiming descent from the Prophet, who held real authority over the Hejaz while acknowledging the nominal sovereignty of whichever greater power dominated the Islamic world. The interior of the peninsula, Najd, remained a patchwork of tribal and oasis principalities largely beyond outside control.
In 1517 the Ottomans, having defeated the Mamluks, gained suzerainty over the Hejaz; the Sharif of Mecca acknowledged the Ottoman sultan as caliph, and Ottoman authority over the holy cities remained largely indirect, leaving day-to-day power with the sharifs. This long era of fragmented and external rule set the stage for the religious revival movement that would emerge from Najd in the 18th century and give rise to the first Saudi state.
“For a thousand years the holy cities were ruled from afar, while the deserts of Najd kept their own counsel.”

The First and Second Saudi States and the Al Saud-Wahhab Alliance
In 1744 a pact between the ruler of Diriyah and a puritan reformer fused religious revival with political ambition, creating the first state of the House of Saud and the religious-political partnership at the kingdom's foundation.
In 1744 in the oasis town of Diriyah in central Najd, the local ruler Muhammad ibn Saud gave refuge and support to the religious reformer Muhammad ibn Abd al-Wahhab, who preached a return to a strict, unadorned monotheism purged of what he saw as later accretions. Their alliance, sealed by the Diriyah pact, joined the political authority of the Al Saud to the religious mission of the reform movement, and this partnership has underpinned Saudi statehood ever since.
The First Saudi State expanded rapidly from Diriyah, bringing much of the Arabian Peninsula under its control and, in the early 19th century, taking Mecca and Medina. This challenge to the Ottoman order provoked a response: between 1811 and 1818 the Egyptian forces of Muhammad Ali Pasha, acting for the sultan, campaigned in Arabia. Ibrahim Pasha besieged Diriyah, which surrendered in September 1818 and was systematically razed, and the last Saudi imam was sent to Constantinople and executed.
The dynasty soon recovered. In 1824 Turki ibn Abdullah Al Saud expelled the occupying forces and re-established Saudi rule with Riyadh as the new capital, founding the Second Saudi State. This realm, narrower than the first, was weakened by internal succession struggles within the Al Saud and by rivalry with the Al Rashid of Hail. In 1891 the Al Rashid overran the Saudi domain, drove the family into exile in Kuwait, and brought the second state to an end, setting the scene for its dramatic 20th-century revival.
“The pact sealed at Diriyah in 1744 bound throne and pulpit together, and that bond has outlasted every fall of the dynasty.”

Unification and the Founding of the Kingdom (1902-1932)
A daring raid on Riyadh in 1902 launched Abdulaziz ibn Saud on a thirty-year campaign that reunited Najd and the Hejaz into the Kingdom of Saudi Arabia.
In January 1902 the young Abdulaziz ibn Saud, returning from exile in Kuwait with a small band of followers, stormed the Masmak fortress in Riyadh and seized the city from the Al Rashid. This audacious recapture of the family's ancestral capital restored the House of Saud to Najd and began the campaign that would build a unified Saudi state.
Over the following decades Abdulaziz extended his control across central and eastern Arabia, drawing on the military zeal of the Ikhwan, tribal warriors loyal to the religious cause. In 1925 his forces took Mecca and Medina, ending the rule of the Hashemite Sharif Hussein in the Hejaz. In 1927 the Treaty of Jeddah saw Britain formally recognize the independence and sovereignty of his realm, then styled the Kingdom of the Hejaz and Nejd.
On 23 September 1932 the two principal regions were merged and proclaimed the Kingdom of Saudi Arabia, with Abdulaziz as its first king. The new state was poor, its economy resting on pilgrimage revenues and trade, but it was unified, internationally recognized, and ruled by a single dynasty for the first time in centuries. Within a few years the discovery of oil would utterly transform its fortunes.
“What began with sixty men scaling a fortress wall in Riyadh ended, thirty years later, in the founding of a kingdom.”

Oil, Modernization and Contemporary Saudi Arabia
The discovery of oil in 1938 turned a poor desert kingdom into a global energy power, financing rapid modernization while the Al Saud navigated regional crises and, more recently, an ambitious drive to diversify beyond oil.
In 1933 Abdulaziz granted an oil concession to the Standard Oil Company of California, and after years of exploration commercial quantities of oil were struck at Dammam Well No. 7 in 1938. The first crude was exported in 1939, and the venture grew into the Arabian American Oil Company (Aramco). Oil revenues transformed state finances, funding roads, schools, hospitals, and a vast expansion of the cities, while the kingdom retained its conservative religious character and its role as custodian of Mecca and Medina.
Wealth brought influence. Under King Faisal, Saudi Arabia led the Arab members of OPEC in the 1973 oil embargo against states supporting Israel, quadrupling oil prices and demonstrating the kingdom's leverage over the world economy. In the decades that followed the kingdom became a pillar of the global oil market, a major regional power, and at times a flashpoint, as in the seizure of the Grand Mosque in 1979 and the basing of foreign troops during the 1990-91 Gulf crisis.
Heritage and identity have also been reclaimed: Hegra, the great Nabataean site, became Saudi Arabia's first UNESCO World Heritage Site in 2008, followed by At-Turaif in Diriyah, cradle of the first Saudi state, in 2010. In 2016 Crown Prince Mohammed bin Salman launched Vision 2030, a sweeping program to diversify the economy away from oil, expand the private sector and tourism, and reshape Saudi society. The kingdom of the 21st century remains defined by the interplay of oil wealth, dynastic rule, and its singular place at the heart of the Islamic world.
“Oil made the kingdom wealthy; Vision 2030 is its wager that the future must be built on more than oil.”
