ABAC or Assumption University as it is now known, was originally initiated in 1969. It was formally established in June 1972 and accredited by the Ministry of Education and the Ministry of University Affairs in May 1975. The founding father of this institution is Brother Bernard Mary of the Brothers of St. Gabriel, a Catholic religious congregation devoted to education and philanthropic activities in Thailand and other countries. The congregation runs 17 educational institutions in the country.

     Beginning its operation on a rather small-scale basis with only 51 students, two classrooms, three administrative personnel, and a part-time faculty, Assumption Business Administration College has grown by leaps and bounds into Assumption University in 1990 with a student body of more than 9,000 including over 500 graduate students and a high-caliber full-time faculty supplemented by a large number of part-time faculty drawn from relevant business circles and government offices.

     Assumption University is the only Founding Member in South East Asia of the International Internet Society with headquarter in the United States and members in 150 countries. The University is also the incubator for Internet KSC, the first and largest Internet Service Provider (ISP) in Thailand.
