MAAC
The MAAC founded its hockey sponsorship starting in 1997 due to NCAA regulations that required all Division I conferences to participate in all Division sports. At the founding of the MAAC hockey conference, only three of the eight founding teams were full members of the conference. The MAAC began play starting with the 1998-99 season and quickly added two additional teams the following year. Army joined the conference for the 2000-01 season, bringing the conference up to eleven member teams. At the conclusion of the 2002-03 season Fairfield and Iona both discontinued their men's ice hockey programs, and while the conference's remaining nine teams could continue without them, having only one full member necessitated the folding of the MAAC hockey conference as the eight associate members had no vote for the legislation the conference passed. The following year all of the teams continued their programs in the newly formed Atlantic Hockey conference.
