The Ottomans
In 1517 the Ottoman sultan Selim I conquered Egypt and proclaimed the Hejaz part of the Ottoman dominions. Sharif Barakāt II of Mecca sent his son to negotiate at the Ottoman court and was confirmed as lord of the Holy Cities and Jiddah, subject to recognizing the Ottoman sultan as overlord. Selim’s successor, Süleyman I the Magnificent, at the zenith of Ottoman power, munificently subsidized the Holy Cities, devoting large sums to new building.
In Yemen the Mamlūks of Zabīd and Taʿizz acknowledged Ottoman authority, and Ottomans took over naval operations against the Portuguese in the Red Sea and Indian Ocean. They seized Aden and forced the Yemenis into the mountains, capturing Sanaa and Shahārah. Ultimately, however, the Yemenis drove them back into the Tihāmah. The Ottomans adopted Mocha (Al-Mukhā) in southern Yemen as their base, and Aden declined in importance. After conquering Iraq in 1534–36, the Ottomans could operate in the Persian Gulf against the Portuguese, who had taken Hormuz and Muscat in 1507 and Bahrain in 1521 and freely harried the Arabian coasts.
The Ottomans reached as far as Al-Ḥasā by 1550 as they sought to curb Portuguese expansion. With Ottoman help, local merchants partially revived the spice trade, especially in pepper, but the Sunni Banū Khālid expelled Ottoman forces in 1670. The Portuguese maintained themselves in Muscat until 1649, although they could hold Bahrain only until 1602, when they were expelled by Ṣafavid Iran, which ruled there until 1717. Many Bahraini Shīʿite scholars in the 17th century moved to Iran, where they led in the development of Shīʿite theology.
Coastal Arabia was coming into direct contact with other Christian European maritime nations, which had begun their commercial penetration of the Indian Ocean. The Dutch, English, and French followed the Portuguese. The Western nations traded with Yemen through Mocha, whose coffee trade began in the 17th century; later the Europeans opened trading stations, or “factories,” there.
By 1635 the Zaydīs of Yemen, supported by the northern tribes, had expelled the Ottomans, and the Zaydīs had their first great, if short-lived, expansion when their tribes moved into much of southern Arabia. The broken terrain made it impossible for them to maintain their supremacy, and local tribes drove out Zaydī garrisons by about the second decade of the 18th century.
In the 17th century Mecca and Medina saw a sharing of power between the locally autonomous sharifs and Ottoman Sunni governors. Mecca was important in the spread and development of Islamic theology, even for Shīʿite thinkers, while the pilgrimage reinforced a common Muslim identity among the far-flung and diverse Muslim communities of the world. In the late 17th and 18th centuries, however, there was confusion and civil war in Mecca, with disputes among the sharifian tribes and struggles at Jiddah with Ottoman officials, who, notwithstanding the virtual independence of the sharifs, still dabbled in Hejaz politics. A new element was introduced in Najd (in central Arabia) in the mid-18th century with the rise of the puritan Wahhābīs, who, because the sharifs regarded them as dangerous heretics, for a time were refused permission to make the pilgrimage to Mecca.
