The Minnesota Public Interest Research Group (also known as MPIRG) describes itself as "a grassroots, non-partisan, nonprofit, student-directed organization that empowers and trains students and engages the community to take collective action in the public interest throughout the state of Minnesota." 
MPIRG was incorporated on February 17, 1971. Students at the University of Minnesota collected 25,200 signatures that year to start the first MPIRG chapter in Minnesota and start the first PIRG in the nation. College students collected more than 50,000 signatures in all to start chapters at college campuses across the state. The motivating idea was for students to join together in collective action to advocate in the public interest, and to use the activity fees they collected from each school to support a staff of professionals that could train them to become powerful advocates in the public policy arena. MPIRG's unique strategy to mobilize students has led to a long list of accomplishments, including protecting the Boundary Waters Canoe Area Wilderness in northern Minnesota from environmental damage and promoting stricter ethical standards for lobbyists. 
In recent years, the financing structure of the organization has come under fire for its reliance on contracts with various post-secondary institutions to receive disproportionately large pools of funding from the student body on an "opt-out" basis. A movement at Macalester College was launched to counter what was seen by some students as unfair, in that funding to MPIRG is taken from each student at the college unless the student has explicitly specified otherwise. Given the political nature of the organization, this has led to contentious debate over the ethics of such a scheme. The movement was successful in ending the deal between MPIRG and Macalester, which has prompted MPIRG to cancel their chapter at the college.
