In 1919, the university was incorporated as a technical faculty of the Latvian University of Applied Sciences (Latvijas Augstskola, since 1923: University of Latvia), which was founded after independence. On September 1, 1958, their technical faculties were spun off again and raised to an independent university. From 1958 to 1983 it was called the Riga Polytechnic Institute, and then renamed the Arvīds Pelše Institute of Technology in Riga (Arvīda Pelšes vārdā nosauktais Rīgas politehniskais institūts). In the mid-1970s, the university became the largest university in the Latvian Soviet Socialist Republic. It has been called the Riga Technical University since March 1990. On April 23, 1992, a student parliament was founded. It is the oldest student self-government in Latvia.
