King Mongkut’s University of Technology Thonburi was founded from Thonburi College of Technology which was under the supervision of the Vocational Education Commission, the Ministry of Education on February 4, 1960. In 1971, Thonburi College of Technology was merged with North Bangkok College of Technology and College of Telecommunication Technology to become King Mongkut’s Institute of Technology Thonburi (KMITT) under the supervision of the Ministry of Education. After that, in 1974 the Institute was upgraded into a state academic institution under the Ministry of University Affairs. In 1986, KMITT became a juristic entity within the Ministry of University Affairs under a royal decree for King Mongkut’s Institute of Technology Lakrabang, King Mongkut’s Institute of Technology Thonburi, and King Monkut’s Institute of Technology North Bangkok.
King Mongkut’s University of Technology Thonburi, by a royal decree in the year 1998, was changed into a state juristic university outside the civil service system but is still under the supervision of the government. The status change was officially declared in the Royal Gazette Volume 115, Section 11 ก on April 4, 1998 and was made effective on March 7, 1998.
