The Disarmament and International Security Council (DISEC), also known as the First Committee, was founded in 1945. Since its establishment, DISEC has been a part of the six primary committees of the UN General Assembly. Thus the committee permits all 195 full members and full observer-status States to partake.

This committee holds a cardinal position in the General Assembly as its primary focus lies on global issues related to demilitarization and security threats on an international and national scale. Due to the increasing rate of disputes and conflicts in the modern world, the involvement and responsibilities of DISEC have increased considerably. Although matters of security and peace reviewed by the Security Council and The First Committee are similar, the difference between the two is that DISEC is a part of the General Assembly and thus does not possess the power to pass resolutions that approve intervention.
