Beginning in 1866, Rutgers was unaffiliated with any formal athletic conference and thus classified as "independent" for eighty years. From 1946 to 1951, the university was a member of the Middle Three Conference, and from 1958 to 1961, was a member of the Middle Atlantic Conference. In 1978, the Rutgers Scarlet Knights became a member of the Atlantic 10 conference. In 1991, it joined the Big East Conference for football. All sports programs at Rutgers New Brunswick subsequently became affiliated with the Big East in 1995.
