It was created by Haryana State Legislative Act No. 17 of 1995 on 20 October 1995 and was formally inaugurated on 1 November 1995. The university is named after Guru Jambheshwar, the fifteenth-century saint associated with environmental stewardship and the Bishnoi tradition. Its founding mandate emphasized technology, pharmacy, environmental studies, non-conventional energy and management, and the academic portfolio has since broadened considerably. The Faculty of Engineering and Technology includes artificial intelligence and data science, civil and environmental engineering, computer science and engineering, electrical and electronics engineering, mechanical engineering and printing technology. Environmental and biological sciences include biotechnology, botany, food technology and zoology. Humanities and social sciences cover applied psychology, economics, English and foreign languages, geography, Hindi, library and information science and mass communication. The university also includes law, allied health sciences, pharmaceutical sciences, physiotherapy, yoga science, commerce, management, chemistry, mathematics and physics. A dedicated Guru Jambheshwar Ji Maharaj Institute of Religious Studies reflects the institution's connection with its namesake and his environmental and ethical teachings. The Hisar campus supports teaching, research, student services and residential facilities within a large public-university setting. GJUST combines foundational sciences with engineering, health sciences, business, law and humanities, allowing interdisciplinary work across technology and societal applications. Its early focus on environmental studies and non-conventional energy remains especially relevant to contemporary sustainability research. The university is recognized under Sections 2(f) and 12B of the UGC Act and operates within Haryana's state-university system.
