Kohima Stone Inscription
Manipuri influence over the Naga tribes declined during a period before and after the Burmese war of 1819-25. However, it was re-asserted during the time of Raja Gambhir Singh (Chinglen Nongdrenkhomba). He reduced many tribesmen villages, including Kohima, at which he stood upon the stone and had his footprints sculpted on it as a token of conquest. Kohima and its surrounding villages were the boundaries of Manipur. The Nagas greatly respected this stone and cleaned it from time to time.
