During 2012-13 the Middle Atlantic Conferences celebrate the MAC 100 to honor a century of intercollegiate competition as one of the oldest intercollegiate athletics associations in the United States. Founded on December 11, 1912, the MAC has evolved into the only intercollegiate sports umbrella organization in the country that includes the Middle Atlantic, Freedom, and Commonwealth Conferences. The first conference competition occurred on May 20, 1913 with a track & field meet at Lafayette College. Since then, 59 institutions have competed in 25 sports and won 33 NCAA team championships. Currently 18 schools, spanning four states, have 6,448 student-athletes competing in 23 sports for 36 conference championships. As the MAC enters its second century, the presidents and athletic administrators have positioned the conference into the strongest, most cohesive structure since its founding.
