The primary purpose of the United Nations when it was founded in 1945 was to foster international cooperation and prevent future conflicts after the devastating effects of World War II. Established on the principles of promoting peace, security, and human rights, the UN aimed to create a platform where nations could engage in dialogue and collective actions. The organization sought to address global issues, provide humanitarian aid, and uphold international law, reflecting a shared commitment to avoiding the mistakes of the past and ensuring a more stable and just world for future generations.
