Kumilla

Kumilla belongs to eastern Bengal, where cultivated plains and low hills linked the delta with the neighbouring upland world. Rice production supported villages, while fishing, craft work and exchange supplemented household resources. Rivers and local paths connected communities with markets and larger centres such as Sonargaon. The landscape carried a deep religious inheritance, including the remains of earlier Buddhist institutions alongside later traditions.

On the edge of the Bengal delta, the wider Comilla region was contested by Bengal's rulers and the kings of Tripura. The Dharmasagar tank in the town is attributed to the fifteenth-century Tripura ruler Dharma Manikya I. Mughal expansion brought much of the surrounding district under Bengal's administration, although Tripura rulers retained landholding rights in parts of it.
