What was the main purpose of the United Nations at its founding?

The primary purpose of the United Nations at its founding in 1945 was to promote international cooperation and prevent future conflicts, especially in the wake of the devastating impacts of World War II. The founders aimed to create an organization that would facilitate dialogue between nations, enhance diplomatic relations, and foster a sense of collaboration on global issues such as peace, security, human rights, and development. By emphasizing collective security and cooperation, the UN sought to address the root causes of conflict and provide a platform for resolving disputes through negotiation rather than warfare.

The other options do not accurately reflect the UN's foundational goals. While international trade and economic cooperation are important aspects of global relations, they were not the primary focus of the UN at its inception. Similarly, increasing military alliances or establishing a global currency were not among the mandates of the UN, which was established to prioritize peace and diplomatic relations among member states.
