Sack of Delhi (1739) was a decisive and devastating seizure of the Mughal capital by Nader Shah of the Persian Empire that culminated in a wholesale plunder, massacre, and political humiliation of Muhammad Shah (Mughal emperor)'s court. The campaign reshaped power relations in South Asia, accelerating the decline of the Mughal Empire and enabling the rise of regional actors such as the Maratha Empire, Sikh Confederacy, and Durrani Empire. The event reverberated through diplomatic relations among Ottoman Empire, Afsharid dynasty, Safavid dynasty, East India Companies, and local polities.

Background

In the early 18th century the Mughal Empire under Muhammad Shah (Mughal emperor) faced internal fragmentation involving provincial governors like the Nawab of Awadh, Nizam of Hyderabad, Jat Kingdom, and Afghan chieftains such as the Rohilla. Simultaneously, the demise of the Safavid dynasty and the rise of Nader Shah in Persia (Afsharid dynasty) followed conflicts like the Ottoman–Persian Wars and revolts involving Esmail III. Nader's consolidation after campaigns in Caucasus and against Ottoman Empire set the stage for eastern ventures; his justification drew on contested Kashmir claims, harassment of Persian pilgrims, and the lucrative prospect of Mughal treasures housed in Shahjahanabad (Old Delhi). Regional contests involved the Maratha Empire expansion following the Battle of Palkhed, tensions with the Sikh Confederacy, and the continuing role of European trading companies such as the British East India Company, French East India Company, and Dutch East India Company in supplying arms and negotiating privileges.

Persian Invasion and Campaign to Delhi

Nader Shah's Iranian forces advanced east after subduing the Afsharid revolt and pacifying the Kurdish and Lezgian frontiers, crossing the Indus River and moving through Lahore, where he defeated local Mughal commanders and Afghan allies including Mughal wazirs and provincial nobles. The decisive march included engagements with Mughal detachments at places linked to the Sutlej and Yamuna riverine lines. In negotiations, envoys from Delhi court such as Qamar-ud-din Khan attempted diplomacy while Nader demanded indemnities and recognition. The Persian campaign exploited Mughal political disunity, circumvented fortified positions like Agra Fort by feints, and took advantage of intelligence from disgruntled courtiers and European Company agents.

Siege and Capture of Delhi

Nader Shah entered the plains south of Shahjahanabad after forcing crossings of the Hindon River and Yamuna River, confronting Mughal field armies commanded by nobles including Itimad Khan and Jahanara Begum's faction rivals. Skirmishes outside the city involved elite units such as the Persian cavalry, Afghan horsemen, Mughal ahadis, and provincial levies from Bengal Subah and Deccan. Following the breakdown of negotiations and a confrontation at the suburb of Kojah, Persian artillery breached suburb defenses, and urban fighting commenced in the lanes of Shahjahanabad. The Mughal court capitulated after key gates fell and the emperor Muhammad Shah (Mughal emperor) was captured, leading to Nader's formal entry into the palace and the Red Fort complex.

Looting, Massacre, and Destruction

Once inside Shahjahanabad, Nader Shah's troops systematically plundered imperial treasuries, seizing regalia including the famed Peacock Throne, jewel-encrusted standards, and the legendary Koh-i-Noor and Darya-ye Noor diamonds. The carnage included massacres in marketplaces and palace precincts; contemporary observers within European Company factories and Mughal chroniclers reported thousands killed during looting and punitive operations allegedly triggered by a scuffle between a Persian soldier and a shopkeeper. The sack saw destruction of architectural elements in the Red Fort, desecration of palatial halls associated with Shah Jahan and Aurangzeb, and loss of administrative records from the Diwan chambers. The removal of bullion, precious stones, and secular regalia was accompanied by forced indemnities exacted from provincial elites such as the Raja of Jaipur and merchants associated with the Jain and Bania communities.

Political and Economic Consequences

The immediate political consequence was the emasculation of imperial authority of Muhammad Shah (Mughal emperor) and the acceleration of autonomy among regional polities: Maratha Empire, Nizam of Hyderabad, Nawab of Awadh, Sikh Confederacy, and various Rajput states asserted greater independence. The transfer of Mughal treasure funded Nader Shah's campaigns in Caucasus and Central Asia, while the depletion of Delhi's bullion destabilized monetary systems tied to Rupee coinage and disrupted trade routes connecting Bengal Subah with Persian Gulf commerce. The perceived weakness encouraged European powers—British East India Company, French East India Company—to seek expanded political influence, and local power brokers such as the Grand Vizier and court factions jockeyed for position. Diplomatic repercussions included strained relations between Afsharid dynasty and the Ottoman Empire as well as renewed attention by Qajar pretenders.

Aftermath and Legacy

Nader Shah's withdrawal left a shattered Shahjahanabad and an emboldened set of provincial rulers; this diffusion of authority prefaced conflicts like the Battle of Bhopal (1737) and later Maratha ascendancy culminating in the Third Battle of Panipat (1761). The removal of the Peacock Throne and jewels such as the Koh-i-Noor entered global provenance debates involving British Crown Jewels and successive regimes. Chroniclers from the Mughal court, observers from British East India Company, and later historians in Persia and India framed the sack as a turning point leading to the eventual British Raj. Architectural and fiscal recovery was uneven: monuments were repaired by later rulers but the political centralization of the Mughal state never recovered, influencing the rise of dynasties such as the Durrani Empire and the political geography antecedent to modern India and Pakistan.
