The system designates four institutions as "research universities": Georgia Institute of Technology, University of Georgia, Augusta University, and Georgia State University. The University of Georgia is the state and system's flagship university, the state's oldest institution of higher learning, and one of the state's two land-grant universities. After its 2016 merger with Georgia Perimeter College, Georgia State University became the largest institution of higher learning in the USG, with over fifty thousand students. University of North Georgia is the state's designated military school. There are three historically black schools housed within the USG: Savannah State University, Albany State University, and the state's second land-grant university, Fort Valley State University.
