In Assam, when did the Ahom revolt against British rule begin?

The 1826 Treaty of Yandaboo, which ended the First Anglo-Burmese War, brought Assam under East India Company administration. When the Company failed to honour its promise of restoring local self-rule and instead tightened direct control, the Ahom nobility organised armed uprisings against the new colonial administration.

The first of these uprisings broke out in 1828, when the Ahom prince Gomdhar Konwar was proclaimed king by his supporters and led an armed revolt against East India Company rule in Assam — marking the start of organised Ahom resistance to British annexation.

• 1830 is the year of a separate, later Ahom uprising led by Dhananjay Borgohain against East India Company rule — a distinct later chapter of the resistance, not this question's starting year.

• 1834 is not associated with any recorded Ahom uprising against British rule in Assam.

• 1844 falls well over a decade after the documented Ahom uprisings and is not linked to any revolt against Company rule in Assam.
