This students' union was established in the academic year of 1923–24 as Dhaka University Student Union (DUSU). Its first constitution was drafted in its general assembly on 30 October 1925. In 1953, its constitution was amended, and the union was renamed Dhaka University Central Students' Union (DUCSU). In the same year, the first election by student vote was held. The first elected VP and GS by student vote were
S. A. Bari and Julmat Ali Khan respectively. Since its establishment, DUCSU elections have been held a total of 38 times, 29 times before 1971 and 9 times after 1971. Unfortunately, this students' union was almost closed after the year 1990–91. Due to political turmoil between student groups, fear of opposition by the government and the disinterest of university officials, students could not elect their representatives for a long time. The last election was held on 9 September 2025. == Constitution ==
