Supranationalism refers to a form of governance or cooperation that transcends national boundaries, where countries come together to make decisions that affect multiple nations. This often involves the creation of international organizations, such as the European Union or the United Nations, which facilitate collaboration on issues like trade, security, and environmental protection. In supranational arrangements, member states may cede some degree of their sovereignty to a higher authority, allowing for collective decision-making. This approach aims to address global challenges more effectively, promoting peace and stability while fostering economic and social development across regions.
