Key UN Agencies and Their Mandates
The United Nations (UN) system comprises six principal organs, specialized agencies, and specialized funds and programmes. While the UN Charter established the principal organs in 1945, various autonomous organizations and specialized bodies work alongside the central UN framework through formal agreements under Articles 57 and 63 of the Charter. These entities address global challenges spanning poverty alleviation, international health, civil aviation, maritime security, trade, human rights, and environmental protection.
