 Ahom rulers would occasionally send expeditions to raid and subjugate the Nagas, and to make them pay tribute, causing tension and hostility to build between the Naga and Assamese at different times.Eventually, the Ahom kingdom grew.By late 14th century onwards, the prevalence of Hindu Brahminic influences on the Ahom rulers (which coincided with the territorial expansion into Hinduized areas) grew also, until slowly the Assamese language gained usage and came to be spoken alongside Tai by the mid-16th century in a bilingual situation.
