The United Nations established the Department of Peacekeeping Operations (DPKO) in 1992 to address the increasingly complex demands of post-Cold War international security.1

Following the end of the Cold War, the nature of conflicts shifted, necessitating a move from "first-generation" peacekeeping—which focused on observing cease-fires between states—to "second-generation" missions. These new operations were designed to address internal instability, protect civilian populations, and achieve multifaceted political and social objectives, such as supervising elections and facilitating humanitarian aid.1

The DPKO was created to provide the necessary administrative and technical support for these expanded political and humanitarian missions. Additionally, the department was tasked with coordinating all mine-clearing activities conducted under UN auspices. This institutional development reflected the UN's broader transition toward integrating peacekeeping, peacemaking, and peace-building efforts to manage threats to international peace and security.1
