Originally founded in 1995 as the Upstate Collegiate Athletic Association, the conference was renamed during the summer of 2004 to the current name.
The league includes founding members Clarkson University, Hobart and William Smith Colleges, the University of Rochester, Rensselaer Polytechnic Institute, St. Lawrence University, Skidmore College, and Union College. Vassar College became a full member of the league during the 2000-01 academic year, and Bard College and Rochester Institute of Technology joined for the 2011-12 academic year. Founding member Hamilton College departed following the 2010-11 academic year in order to fully integrate its athletic programs within the New England Small College Athletic Conference (NESCAC).
At the beginning of the 2012-2013 season, New York University became an associate member in both men's and women's golf, while Wellesley College and Mount Holyoke College became associate members in women's golf.
Offensive linesman Ali Marpet of Hobart and William Smith Colleges, drafted in the 2nd round, 61st overall, of the 2015 NFL draft, is the highest-drafted pick in the history of Division III football. He was three-time All-Liberty League first team (2012, 2013, 2014), and 2014 Liberty League Co-Offensive Player of the Year—the first offensive lineman in league history to be so honored.
