Mughal armies had swallowed most of North India. One kingdom in the Brahmaputra Valley fought them to a standstill, on water, and kept its independence for another two centuries.

Founding and Early Expansion Need to Know
- The Ahom Kingdom was founded in 1228, in the Brahmaputra Valley of present-day Assam.
- Its first king, Chaolung Sukaphaa, arrived from Mong Mao with three queens, two sons, nobles, and soldiers.
- Sukaphaa established his capital at Charaideo.
- The Ahoms were originally a Tai people. Over the centuries, they gradually adopted Hinduism and the Assamese language.
- The kingdom lasted nearly 600 years, one of the longest-ruling dynasties in Indian history.
The Battle of Saraighat, 1671 Need to Know
- The battle was fought in 1671, on the Brahmaputra River near present-day Guwahati.
- Ahom general Lachit Borphukan commanded the defence against a much larger Mughal force.
- The Mughal army was led by Raja Ram Singh I of Amber, serving the Mughal empire.
- Lachit used naval guerrilla tactics on the river, despite being heavily outnumbered.
- The Ahoms won decisively, permanently ending serious Mughal attempts to conquer Assam.

Administration: The Paik System Good to Know
- The Paik system was the Ahom kingdom’s core administrative and labour structure.
- Every adult male aged 16 to 50 was registered as a paik, owing service to the state instead of paying tax in cash.
- Paiks were organised in a clear hierarchy: a Bora oversaw 20 paiks, a Saikia oversaw 100, and a Hazarika oversaw 1,000.
- This system supplied the kingdom’s soldiers, farmers, and craftsmen, without relying on a large standing bureaucracy.
Decline and British Annexation Great to Know
- The Moamoria Rebellion (1769-1805) was a prolonged internal revolt that badly weakened Ahom central authority.
- That internal weakness left the kingdom exposed. Three separate Burmese invasions struck Assam between 1817 and 1826.
- The Treaty of Yandabo, signed on 24 February 1826, ended the First Anglo-Burmese War.
- Under that treaty, Assam was annexed to British India, formally ending Ahom rule.
- Don’t treat the Treaty of Yandabo as a sudden collapse. Decades of internal rebellion had already weakened the kingdom well before the Burmese and British got involved.
