The Assamese Language Movement (Assamese: /ɔxɔmia bʱaxa andʊlɔn/) refers to a series of political activities demanding the recognition of the Assamese language as the only sole official language and medium of instruction in the educational institutions of Assam, India.
The struggle for the use of Assamese for official purposes, in courts and as a medium of instruction in educational institutions began in the nineteenth century, when the region was under the British rule. The use of Bengali in Assam as the language of the courts was resented by the Assamese people and also by American Baptist Missionaries such as Nathan Brown.
Following the agitations for linguistic states in various part of India and the States Reorganization Act (1956), the Assam Sahitya Sabha demanded the use of Assamese as the official language in Assam. This was followed by political movements supporting it and also opposing it. The Assam Official Language Act was passed in 1960, recognizing Assamese as an official language in Assam, while also having provisions for the safeguard of linguistic minorities.
