At that time, Arcadia and Lycoming moved from the MAC Commonwealth to the MAC Freedom, while Eastern made the opposite move. In May 2019, the MAC announced it would realign the Commonwealth and Freedom conferences into two equally-sized leagues effective with York's arrival in 2020. In April 2019, the MAC announced that York College of Pennsylvania would join the MAC Commonwealth in 2020–21. Three months later, the MAC announced that Stevens Institute of Technology, which had left the conference in 1978, would return in 2019–20 and replace Manhattanville in the MAC Freedom. Manhattanville was a charter member of the Skyline before leaving to join the MAC in 2007. In May 2018, Manhattanville College announced that they would leave the MAC Freedom Conference and return to the Skyline Conference for the 2019–20 academic year. Elizabethtown College moved to the Landmark Conference for 2014–15. Stevenson University and Hood College accepted invitations to join the MAC and MAC Commonwealth starting with the 2012–13, expanding the conference to 18 members. Starting in the 2009–10 school year, Alvernia switched from the MAC Freedom to the MAC Commonwealth, thereby giving the Commonwealth and Freedom leagues the same number of members. To offset the change in numbers, it was also decided to switch Lycoming College from the MAC Freedom to the MAC Commonwealth.Īlvernia University, Misericordia University, and Eastern University, all from the Pennsylvania Athletic Conference, accepted membership in the MAC Freedom and started participation in the 2008–09 school year. They replaced Juniata College, Drew University, Moravian College, Susquehanna University, and the University of Scranton, who left to join the new Landmark Conference. Īrcadia University and Manhattanville College joined MAC Freedom for 2007–08. In 1999, the current corporation formed with its three conferences: MAC Commonwealth, MAC Freedom, and Middle Atlantic. An additional 11 members left in 1992 to form the Centennial Conference the football programs for eight of those schools had already left in 1981. At that time, 11 members left to form the Division I East Coast Conference and by 1976, the MAC became fully associated with Division III. A major reduction in the league occurred in 1974 after the NCAA created Divisions I, II, and III. The conference had as many as 37 members at one time in the late 1950s. Throughout its history, the organization has had at least 50 different members associated with it. In addition, another five members who were not present at the initial meeting but formally approved of the plan were: Columbia University, Johns Hopkins University, Lehigh University, Ursinus College, and Widener University. The original 13 members present at the formation meeting in 1922 were: Bucknell University, Drexel University, Franklin & Marshall College, Gettysburg College, Haverford College, Muhlenberg College, New York University, Princeton University, Rutgers University, Stevens Institute of Technology, Susquehanna University, Swarthmore College, and the University of Delaware. In 1922, it was reorganized as the Middle Atlantic States Collegiate Athletic Conference ( MASCAC or MAC).

In 1912, the Middle Atlantic States Collegiate Athletics Association ( MASCAA) was founded primarily as a track association and had its first event, a track meet, at Lafayette College in May 1913.
