How did British control of Bengal affect Tripura after 1765?

When the British East India Company acquired the diwani, or financial administration, of Bengal in 1765, the portion of Tripura that had previously been under Mughal rule transitioned to British control.1

Following this shift, the relationship between the British and the rulers of Tripura became increasingly formalized. Beginning in 1808, every successive ruler of Tripura was required to receive formal investiture from the British government. By 1905, the region was attached to the newly created province of Eastern Bengal and Assam and was designated as Hill Tippera.1
