Tripartite Treaty of 1838 and Afghan Politics

The Tripartite Treaty of June 26, 1838, was a major geopolitical agreement between the British East India Company, Maharaja Ranjit Singh of the Sikh Empire, and the deposed Afghan ruler Shah Shuja-ul-Mulk. Signed at Lahore, the treaty aimed to counter Russian expansion toward British India during the Great Game and replace Dost Mohammad Khan on the throne of Kabul with Shah Shuja.

Geopolitical Context and the Great Game

During the 1830s, British authorities feared Russian encirclement through Central Asia and Persia. Russian influence grew in Persia, culminating in the Persian siege of Herat in 1837 with Russian support. Governor-General Lord Auckland sent Alexander Burnes on a diplomatic mission to Kabul in 1837. Dost Mohammad Khan, the Barakzai ruler of Kabul, expressed willingness to ally with the British. In return, he requested British assistance in recovering Peshawar from Maharaja Ranjit Singh, who had annexed the city in 1834. Lord Auckland rejected Dost Mohammad’s demand, refusing to alienate Ranjit Singh. Dost Mohammad then turned to Russian envoy Captain Jan Vitkevich, prompting Lord Auckland to seek regime change in Kabul.

Negotiations and Signatories

Lord Auckland sent Sir William Macnaghten to Lahore in May 1838 to negotiate a joint plan with Maharaja Ranjit Singh and Shah Shuja, the exile Popalzai Durrani ruler living under British protection in Ludhiana. The agreement, known as the Tripartite Treaty, was signed on June 26, 1838, at Lahore.

Key Terms and Provisions of the Treaty

The Tripartite Treaty contained 18 operational articles that reshaped regional boundaries and foreign policy obligations.

• Restoration of Shah Shuja: The British and Sikh governments agreed to place Shah Shuja on the throne of Afghanistan through combined military action.
• Renunciation of Territorial Claims: Shah Shuja formally surrendered all Afghan claims to territories conquered by Ranjit Singh. These included Peshawar, Kashmir, Multan, Attock, Derajat, and the trans-Indus tracts.
• Settlement on Sindh: Shah Shuja agreed to relinquish all historic claims of Afghan suzerainty and tribute over the Amirs of Sindh. In return, the Amirs paid an indemnity of 20 lakh rupees, with 15 lakh rupees allocated to Ranjit Singh to settle old debts.
• Foreign Policy Control: Shah Shuja pledged not to enter into negotiations with any foreign power, including Russia and Persia, without the express consent of the British and Sikh governments.
• Military Coordination: The Sikh army agreed to provide a division to support Shah Shuja’s advance through the Khyber Pass, while the British formed the “Army of the Indus” to advance through Sindh and the Bolan Pass.
• Prohibition of Interference: Shah Shuja recognized the absolute independence of the Sikh Empire and pledged non-interference in Sikh territories.

Execution and the First Anglo-Afghan War

The treaty served as the immediate trigger for the First Anglo-Afghan War (1838–1842). The British assembled the Army of the Indus under Sir John Keane, marching through Sindh and southern Afghanistan.

Campaign Milestones

• April 1839: British and Allied forces captured Kandahar without major resistance.
• July 1839: The British captured the fortress of Ghazni after breaching the Kabul Gate.
• August 1839: British troops entered Kabul, deposed Dost Mohammad Khan, and placed Shah Shuja on the throne. Dost Mohammad surrendered in 1840 and was exiled to Calcutta.

Collapse of the Settlement

Shah Shuja relied entirely on British bayonets to maintain authority, making his rule unpopular among Afghan tribal chiefs. Maharaja Ranjit Singh died in June 1839, reducing active Sikh involvement in Afghan affairs. In November 1841, an uprising broke out in Kabul led by Akbar Khan, son of Dost Mohammad Khan. British political agents Alexander Burnes and William Macnaghten were murdered. In January 1842, Major General William Elphinstone led a force of 4,500 soldiers and 12,000 camp followers in a retreat toward Jalalabad. Afghan tribal fighters killed nearly the entire force in the mountain passes, leaving Assistant Surgeon William Brydon as one of the few survivors to reach safety. Shah Shuja was assassinated outside Kabul in April 1842. The British dispatched an “Army of Retribution” under Generals George Pollock and William Nott later in 1842 to destroy the Kabul bazaar before evacuating Afghanistan completely. Dost Mohammad Khan returned to Kabul and reclaimed the throne.

Fact Summary on the Tripartite Treaty

The British violated their 1832 commercial treaty with the Amirs of Sindh by marching the Army of the Indus through Sindh territory to execute the terms of the Tripartite Treaty in 1838. Sir William Macnaghten served as the chief architect of the treaty and later became the British Envoy and Minister to the court of Shah Shuja at Kabul until his assassination in December 1841. Maharaja Ranjit Singh refused to allow British troops to march across main Punjab territory toward Afghanistan, forcing the Army of the Indus to take a circuitous route through Sindh and the Bolan Pass. Shah Shuja had previously ruled Afghanistan from 1803 to 1809 before being deposed by his half-brother Mahmud Shah and seeking refuge in British India. Following the British withdrawal in 1842, Lord Ellenborough ordered the return of the wooden doors from the tomb of Mahmud of Ghazni, falsely believing they were the original gates of the Somnath temple taken in 1026.
