Final answer:
The United Nations, established in 1945 to promote global peace and security, consists of main bodies such as the General Assembly, the Security Council, and the Secretariat, along with specialized agencies like the WHO, UNHCR, and the Human Rights Council. It provides a platform for its 193 member states to address international issues collectively.
Step-by-step explanation:
The United Nations: Origin and Structure
The United Nations (UN) is an international organization created in 1945 with the primary objective of maintaining international peace and security. Its founding followed the end of World War II, with 51 countries initially committing to its establishment, in an effort to avoid the horrors of war witnessed. The UN has since expanded to 193 member states, with the Holy See and Palestine having observer status.
Main Bodies of the UN
The UN is organized into six principal bodies: the General Assembly (UNGA), the Security Council (UNSC), the Secretariat, the International Court of Justice, the Economic and Social Council, and the currently inactive Trusteeship Council. New member states are admitted and the UN budget is approved by a two-thirds majority within the General Assembly. The Security Council, with fifteen member states including five permanent members (the US, the UK, France, China, and Russia), addresses issues pertaining to international peace and security.
The Secretariat, led by the Secretary-General, performs administrative duties and coordinates with various large organizations under the UN umbrella such as the World Health Organization (WHO), the United Nations High Commissioner for Refugees (UNHCR), and the Human Rights Council. These organizations work alongside the main UN bodies to address global issues.
Tools for Peacekeeping
The UN maintains peace by providing a platform for dispute resolution and transparency, and can deploy peacekeepers under certain guiding principles to conflict zones with the authorization of the Security Council.
Overall, the UN embodies a hub for global governance and cooperation, addressing a vast array of issues from humanitarian aid to environmental challenges.
