High Quality Content by WIKIPEDIA articles! The Assamese people are a well-defined subgroup of People of Assam. Though sometimes they are defined as the Assamese-speaking Indo-Aryans of the Brahmaputra valley,, this definition is not legally binding. Historically, the definition of the "Assamese people" has remained in flux and this has had strong political repercussions in Assam, especially in the colonial (1826-1947) and post-colonial (after 1947) periods. Attempts in the past to define the Assamese people on linguistic, cultural or ethnic basis have failed.
