Medical journals and their editors have a unique responsibility in armed conflicts. The experience of the Croatian Medical Journal during and after the 1991–1995 war in Croatia shows how a medical journal can survive, help others and learn in times of war. The first duty of a medical journal in such circumstances is to publish scientific articles on various aspects of war medicine, and to document cases of human rights abuses. In small scientific communities, editors can offer their expertise and assist authors in writing and publishing war-related research and reports. In post-conflict period, medical journals have a responsibility to participate in peace-building and reconciliation efforts. They can do so by publishing good scientific articles regardless of their place or country of origin, re-establishing contacts with colleagues from the opposing sides, striving for the multiethnic or multinational Editorial and Advisory Boards, and engaging in collaborative research and regional initiatives.
