The full name of ABSU is All Bodo Students' Union Association. It's a non-political and democratic Students' body of Bodo community and was formed on 15th February in 1967 at Tribal rest house. Before the formation of ABSU, many Bodo Students' club, Sonmilon, Conference and associations were existed in many districts independently without lacked of proper relation and co-ordination. The protagonist and thinkers of Bodo nationalism of that era conceived the idea to unite and append the Bodo students under a single banner with a view to develop mutual relationship and bond of unity among the Bodo community and to develop language and literature, as well as to bring social order was also their prime objectives and thus they striven and did.

  
The ABSU has the committees in West Bengal, Meghalaya, Nagaland, New Delhi, Pune, Tripura apart from Assam and Nepal and Bangladesh abroad. The emergence of ABSU is the emergence of political consciousness among the Bodos and other tribals of Assam and inflamed the linguistic and socio-culture movement in Assam and some parts of India. However, irony of the fact is that ABSU was compelled to lead some movements with political nature albeit it's a non-political per se. To get back the land from the illegal migrants who illegally occupied tribal's land in Tribal belt and Block areas, the ABSU had spearhead Land Restoration Movement from 1972 to 1980. The Union also takes active part avidly in every needs and crisis of Bodo Sahitya Sabha (BSS) and joined in the language and script movement in 1970s.
  
The question of protection of identity and survival actually arose in the minds of BODO intelligentsia, which was endangered by the antipathy and step motherly attitudes of Assam Government and chauvinistic group of Assamese ruling clique. The ABSU could not tolerate the silent aggression policy to smother and assimilate the Bodo and other tribal language of the State by imposing Assamese language of the non-Assamese speaking people, e.g. in 1960 through the campaign of only Assamese as a compulsory in the state and so also in 1985 through a circulation of SEBA to make Assamese as a compulsory subject in the schools. Due to such silent aggressive tactics applied on Bodos in time and tide, the Bodo community was close its extinct i.e. the identity of Bodos was about to disappeared from the world. However, the ABSU could never compromise on the greater interest of the community and allow to denigrate the dignity and always ready to protect and preserve its rich culture, language, literature and colourful tradition keeping pace with the development of human civilization and century. So, to fight against the silent aggressor and to solve the identity and existence of Bodos became an urgent need of the period and onus of ABSU. Since its formation and inception in activities, ABSU has been marching forward with its ultimate aim to establish the Bodo community as distinct nationality in the world and a master race of course.
  
In 1986 Upendra Nath Brahma, later entitled 'Bodofa' (Father of Nations) became the 8th President of ABSU and it was under his Presidentship that the ABSU resolved to lead direct political movement demanding a separate state for the Bodos and other plains tribal people to be curved out of Assam. The ABSU launched an independent mass movement from 2nd march 1987 on the basis of 92 charters of demands. Later only three major demands were taken up detaching the remaining ones and were (i) creation of Separate State of Bodo land on the northern bank of Brahmaputra river (ii) creation of two District Councils on the southern bank of Brahmaputra and (iii) inclusion of the Boro-Kacharies of Karbi-Anglong into S.T (Hills) list. The movement gained momentum and was the greatest ever mass upsurge and struggle in the modern history of Bodos for their constitutional and human rights where the protection and preservation of the identity of the Bodo language, culture and tradition had been given prime priority. It continued phase for six years and temporarily came to an end by signing the historic Bodo Accord on 20th February 1993 in between the Center-State Governments and the Bodo leaders, by this accord Bodoland Autonomous Council (BAC), a new administration within the state was set up.

  
But, this six years Bodoland movement has the unprecedented of the violation of human rights by government in the name of crushing down the mass movement. As many as 1135 Bodos including a few non-Bodos agitators were brutally killed and some were made handicapped out of torture by the police and Para military forces and some hundreds women were rapped. Besides many of the Bodo villages were burnt into ashes by the chauvinistic Assam police and extremists. These and those in human and injustice activities of the State Govt. and its forces still hurt the sentiment of the Bodos and ABSU could never forget it.
  
In 1996, the ABSU denounced the 1993 Bodo Accord due to reticent and evasive attitude of the government on boundary demarcation and major problems of BAC and started the demand of Separate State of Bodoland afresh. The ABSU with its allied organization - Bodo people's Action Committee (BPAC), Bodo Sahitya Sabha (BSS), All Bodo Women's Federation (ABWWF), and Co-ordination Committee for Bodoland movement (CCBM) is still trying to have Bodoland. It has become an inevitable of ABSU to liberate the community from the suppression, political exploitation and persecution and to develop equally at per with other communities of India and trying to give economic opportunity and political power to serve their own interest.
  
The ABSU has widely been recognized by the world today and has also been capable to represent the great Bodos in the world. In the process of building Bodo nationality, the ABSU has got thirty four years' long history of struggle and sacrifice that have already elevated the status and dignity of the community up to reasonable level. Even, today the ABSU is also stick to its resolution and has strong determination to protect, preserve and uplift the Bodos and to achieve the cherished destination which has become a fair and squire realization to grapple with all odds and challenges in the centuries to come
