The United Nations (UN) was established in 1945, following the end of World War II. Its foundation aimed to promote peace, security, and cooperation among nations to prevent future conflicts. The UN emerged from the desire to rectify the failures of the League of Nations and to foster international dialogue on issues affecting global stability, human rights, and development. With its headquarters in New York City, the UN continues to play a pivotal role in mediating international disputes and addressing global challenges such as poverty, climate change, and humanitarian crises.
