The Historical Security Council (HSC) is a specialized simulation of the United Nations Security Council designed to revisit and analyze pivotal moments in international relations through a diplomatic lens. Unlike the contemporary Security Council, the HSC places delegates in historically significant contexts, tasking them with resolving crises using the knowledge, alliances, and resources available at that specific time. It operates under the same structural framework as the Security Council, containing five permanent members with veto power and ten rotating non-permanent members, but its focus is rooted in historical accuracy and critical re-evaluation. At its core, the HSC seeks to challenge delegates to reconsider decisions that shaped global security, explore alternative diplomatic outcomes, and understand the long-lasting consequences of international policy. The principal purpose of the HSC is to provide leadership and insight into past crises, to cultivate a deeper knowledge of global governance through the study of precedent, and to minimize the recurrence of such conflicts by learning from history. Through research, debate, and negotiation, the Historical Security Council works towards a world in which lessons from the past inform the solutions of the present and the future.
