Five Colleges, Incorporated is a nonprofit educational consortium established in 1965 to promote the broad educational and cultural objectives of its member institutions, which include four private, liberal arts colleges and the Amherst campus of the state university. The consortium is an outgrowth of a highly successful collaboration in the 1950s among Amherst College, Mount Holyoke College, Smith College, and the University of Massachusetts Amherst, which resulted in the founding of a fifth institution, Hampshire College, in 1970.
