Afghan supremacy is brief.

Tahmasp Quli, a chief of the Afshar tribe, soon expels the Afghans in the name of a surviving member of the Safavi family.

He then assumes power in 1736 in his own name as Nader Shah.

He goes on to drive the Ottomans from Georgia and Armenia and the Russians from the Iranian coast of the Caspian Sea and restores Iranian sover eignty over Afghanistan.

He also takes his army on several campaigns into India, sacking Delhi in 1739 and bringing back fabulous treasures.

Nader Shah achieves political unity but his military campaigns and extortionate taxation prove a terrible drain on a country already ravaged and depopulated by war and disorder, and in 1747 he is murdered by chiefs of his own Afshar tribe.

A period of anarchy marked by a struggle for supremacy among Afshar, Qajar, Afghan, and Zand tribal chieftains folows Nader Shah's death.

Karim Khan Zand (1750-1779) is finally able to defeat his rivals and unify the country, except for Khorasan, under a loose form of central control.

He refuses to assume the title of shah, however, preferring to rule as vakil al ruaya, or deputy of the subjects.

He is remembered for his mild and beneficent regime.

The Middle East: 1744–1755 CE

Consolidation of the Wahhabi-Saudi Alliance

Between 1744 and 1755, the alliance between Muhammad ibn Abd al Wahhab and Muhammad ibn Saud significantly solidifies, transforming Ad Diriyah into a powerful political and religious center in central Arabia. United by a mutual commitment to the strict reformist Islamic doctrine of Wahhabism, they undertake a campaign to unify surrounding tribes under their authority. Muhammad bin Saud provides the essential political and military leadership, while Muhammad ibn Abd al Wahhab’s rigorous interpretation of Islam offers a powerful ideological framework. In 1744, they formally cement their alliance through a traditional Muslim oath, pledging mutual support to establish a state governed strictly by Islamic principles. This pivotal partnership sets the foundation for a future Saudi state, emphasizing the Al Saud family's clearly defined religious mission and political authority.

Turmoil and Dynastic Change in Oman

In Oman, political instability deepens following the collapse of Yarubid authority. After the death of Saif bin Sultan II, Ahmad bin Said al-Busaidi, governor of the Suhar garrison, emerges as a strong contender for leadership. Ahmad bin Said successfully drives out the last Persian forces from Oman in 1747, capitalizing on internal conflicts arising from Nader Shah's declining Persian empire. He decisively assumes control, culminating in his election as Imam of Oman, Zanzibar, Pemba, and Kilwa in 1749, marking the establishment of the Al Bu Sa'id dynasty. Ahmad shifts the capital from the traditional Ibadi stronghold of Ar Rustaq to Muscat, significantly distancing his rule from traditional Ibadi political structures.

Decline of Nader Shah and Persian Instability

The period sees the rapid decline and eventual assassination of Nader Shah in 1747, causing severe instability throughout Persia. His death plunges the region into factional conflict, significantly reducing Persian influence in neighboring areas, including the Persian Gulf and Iraq. The resulting power vacuum heightens regional instability, facilitating local tribal resurgence and diminishing centralized governance.

Ottoman Authority and Growing Tribal Autonomy

Ottoman control continues to wane, increasingly challenged by tribal autonomy and internal dissent. Powerful tribal confederations such as the Muntafiq and Bani Lam assert greater independence, severely limiting Ottoman influence. The Baban Dynasty in Iraqi Kurdistan fortifies its position, maintaining autonomy and resisting direct Ottoman governance. These tribal dynamics reinforce fragmented control, severely constraining Ottoman central authority.

Economic and Social Dynamics in the Persian Gulf

Despite ongoing political turbulence, economic conditions on the Arab side of the Persian Gulf remain comparatively stable due to trade, pearl harvesting, and limited agriculture. This economic vitality attracts tribes from the Arabian interior, notably the Al Thani, who settle in Qatar during the early to mid-eighteenth century. Originally Bedouin, the Al Thani transition to fishing, pearling, and cultivation of date palms, playing a crucial role in the economic landscape of the region.

Legacy of the Era

From 1744 to 1755, significant political realignments shape the Middle East profoundly. The Wahhabi-Saudi alliance consolidates power in central Arabia, laying firm foundations for Saudi influence. Oman undergoes a critical dynastic shift with the rise of the Al Bu Sa'id dynasty, enhancing internal cohesion and reducing external interference. Persian instability following Nader Shah’s assassination intensifies regional volatility, while persistent tribal autonomy severely curtails Ottoman control. These intertwined developments profoundly impact subsequent decades, setting the stage for continued political, religious, and social transformations.
