The CAA was founded in 1979 as the ECAC South basketball league. It was renamed the Colonial Athletic Association in 1985 when it added championships in other sports (although a number of members maintain ECAC affiliation in some sports). As of 2006, it organizes championships in 21 men's and women's sports. The addition of Northeastern University in 2005 gave the conference the NCAA minimum of six football programs needed to sponsor football. For the 2007 football season, all of the Atlantic 10 Conference's football programs joined the CAA football conference, as agreed upon in May 2005.
