The University of North Carolina at Chapel Hill, also known as UNC-Chapel Hill, UNC, Chapel Hill, North Carolina, or simply Carolina is a public research university in Chapel Hill, North Carolina. It is the flagship of the 17 campuses of the University of North Carolina system. After being chartered in 1789, the university first began enrolling students in 1795, which also allows it to be one of three schools to claim the title of the oldest public university in the United States. Among the claimants, the University of North Carolina at Chapel Hill is the only one to have held classes and graduated students as a public university in the eighteenth century.The first public institution of higher education in North Carolina, the school opened its doors to students on February 12, 1795. The university offers degrees in over 70 courses of study through fourteen colleges and the College of Arts and Sciences. All undergraduates receive a liberal arts education and have the option to pursue a major within the professional schools of the university or within the College of Arts and Sciences from the time they obtain junior status. Under the leadership of President Kemp Plummer Battle, in 1877 North Carolina became coeducational and began the process of desegregation in 1951 when African-American graduate students were admitted under Chancellor Robert Burton House. In 1952, North Carolina opened its own hospital, UNC Health Care, for research and treatment, and has since specialized in cancer care. The school's students, alumni, and sports teams are known as "Tar Heels".
