Indigenous students of Rajshahi University yesterday demanded the communities' constitutional recognition and introduction of their own mother languages in their primary education.
They raised the demands while addressing a human chain in front of the main entrance of the university.
They also protested the rape of an indigenous woman in Gomostapur upazila of Chapainawabganj district last Monday.
They demanded formation of a separate land commission for the indigenous communities.
The communities played a vital role in different crucial movements, including the 1952 Language Movement and 1971 Liberation War, they said.
Although the indigenous people contribute a lot to the national economy, they are deprived of their rights, they alleged.
Earlier on Monday, the indigenous woman, also a Union Parishad member, was beaten up and raped by 30-35 people when she refused them to pay an extortion money of Tk 3 lakh while she was working at her paddy field, claimed the victim.
Prof Sujit Sarker, a teacher of RU Bangla department; Bivutivushan Mahatma, central president of Adivasi Chhatra Parisad; and Hemonta Chandra Mahato, RU unit president, among others, addressed the programme.
