The Ahom–Mughal conflicts marked one of the most intense and significant regional resistance movements against the expansionist policies of the Mughal Empire in eastern India. Spanning several decades (early 17th to late 17th century), these battles reflect the military resilience, diplomatic strategy, and heroic leadership of the Ahoms.
Early Skirmishes and Battles (1616–1639)
Tensions escalated when the Mughals, under Subahdar Qasim Khan, advanced toward Ahom territories in Western Assam.
The Ahoms, under Pratap Singha (1603–1641), organized a strong resistance against Mughal attempts to control Guwahati and adjoining areas.
Between 1616 and 1639, a series of border clashes and battles took place.
The Ahoms sought to:
Defend Guwahati and the Brahmaputra Valley
Maintain sovereignty west of the Barnadi River
🔑 These early confrontations laid the foundation for prolonged hostilities, leading to famous battles and peace treaties.
Major Battles and Peace Treaties
🔹Bharali Battle (1616)
Fought between Ahom forces and the Mughals under Qasim Khan.
Location: Near the Bharali River, central Assam.
Outcome:
The Ahoms inflicted heavy casualties on the Mughal army.
Qasim Khan was defeated and forced to retreat.
🔑 This was the first major Ahom victory over the Mughals and boosted confidence in local resistance.
🔹Battle of Hajo (1618)
Fought at Hajo, an important religious and strategic town.
The Mughals re-attempted to advance into Ahom territory.
The Ahoms, though initially successful, eventually lost Hajo, and the town was occupied by the Mughals.
🔑 Despite the temporary loss, the battle showed the importance of Hajo as a contested site for both spiritual and military control.
🔹Treaty of 1639 (Barnadi & Asurar Ali Boundaries)
After continuous warfare, both sides signed a peace treaty in 1639.
The treaty defined clear boundaries:
Barnadi River: Eastern boundary of Mughal territory.
Asurar Ali (a trench): Western limit of Ahom control.
It established a buffer zone, reducing direct conflict for a time.
🔑 This treaty symbolized a stalemate, acknowledging the strength of the Ahoms and preventing Mughal overreach into Assam.
Invasion by Mir Jumla (1662–63)
In 1662, Mir Jumla, the Mughal general and governor of Bengal, launched a massive military invasion into Ahom territory under the orders of Emperor Aurangzeb.
Key developments:
Guwahati and Garhgaon were captured.
The Ahom king Jayadhwaj Singha fled into the hills.
The capital was looted, and large quantities of wealth were seized.
🔑 This was the deepest Mughal penetration into Assam but proved unsustainable due to terrain, monsoon, and guerrilla resistance.
🔹Treaty of Ghiladharighat
To end hostilities, the Treaty of Ghiladharighat was signed in 1663.
Terms:
The Ahoms agreed to pay tribute and compensation.
Hostages, including a royal prince, were handed over.

🔑 The treaty showed the temporary Mughal dominance, but also exposed the limits of imperial control in remote regions.
Battle of Saraighat (1671)
A decisive battle, fought on the Brahmaputra River near Guwahati.
Ahom general Lachit Barphukan, known for his valor and strategic brilliance, led the resistance.
Despite being outnumbered, the Ahoms used:
Guerrilla tactics
Naval warfare
Knowledge of riverine geography
