This special issue presents a series of papers by scholars who participated in a workshop entitled ‘Men's Groups: Challenging Feminism’, which was held at the University of British Columbia (UBC), Canada, 26-27 May 2014. The workshop was organised by Susan B Boyd, Professor of Law and Chair in Feminist Legal Studies at the UBC Faculty of Law, and was sponsored by the Peter Wall Institute for Advanced Studies at UBC, the Peter A Allard School of Law, the Centre for Feminist Legal Studies at UBC, and the Canadian Journal of Women and the Law. The aim of the workshop was to bring together feminist scholars from multiple disciplines and multiple national contexts to explore a source of resistance to feminism that has been largely overlooked in scholarly research: the growing number of nationally situated and globally linked organisations acting in the name of men's rights and interests which contend that men are discriminated against in law, education and government funding, and that feminism is to blame for this. This special edition presents eight papers inspired by the workshop, authored by scholars from Canada, New Zealand, Poland, Sweden and the United States. A second special issue comprised of eight other papers inspired by the workshop was published in the Canadian Journal of Women and the Law as volume 28(1) in 2016.
