Agartala

Agartala lies on the Haora, or Saidra, River in Tripura's lowland plain, close to the edge of eastern Bengal. Heavy monsoon rain, wooded hills and annually flooding fields made the valley productive but difficult to control. Floodwater laid down fertile silt, but shifting channels forced villages to adjust fields and routes. Its mixed population included Tripuri communities of the hills and Bengali cultivators, traders and officials of the plains. The name is usually derived from agar, the fragrant Aquilaria tree, and tala, beneath.

Twipra was one of the major kingdoms of the Tripuri people. Court pandits compiled the Rajmala in Bengali under Dharma Manikya I, blending royal genealogy with the political memory of the Manikya dynasty. Ratna Manikya I moved the capital to Rangamati, later Udaipur, on the Gomati River. Coins, temples and Sanskrit inscriptions expressed a Hindu court culture, while the Kokborok-speaking population and numerous clan communities retained local institutions. Hill chiefs and the royal court were linked through ritual, marriage, tribute and appointed authority.

Dhanya Manikya expanded the kingdom into eastern Bengal in the late fifteenth and early sixteenth centuries. Twipra resisted repeated Turkic, Afghan, Mughal, Burmese and Arakanese campaigns, although much of its western plain eventually became a Mughal client territory. The forested hills remained the dynasty's core. Rice paddies occupied the floodplain, while bamboo, timber and cotton came from the foothills. Bengal supplied cloth, salt and metal goods, and river traffic carried rice, elephants and forest produce toward lowland markets.

In the eighteenth century the court shifted toward the Haora valley and established the site called Old Agartala or Haveli. Its position shortened the distance to Bengal while leaving access to the hills. A royal residence, markets and religious foundations drew artisans and officials, and boats supplied the settlement along the Saidra. Ferries, markets and monsoon roads connected this lowland court to the hills and to Bengali traders. The river also served royal purchasing, taxation and visiting envoys. British influence expanded after 1808, but the kingdom retained internal government. By 1837 the place was still a modest riverine capital district, with its royal residence, markets and river traffic shaping the surrounding countryside.
