Supranational organizations influence national sovereignty by establishing regulations, norms, and obligations that member states must adhere to, which can limit their autonomy. Examples include the European Union and the United Nations, which often promote collective decision-making on issues like trade, security, and the environment. While such organizations facilitate cooperation and address global challenges, they may also challenge traditional notions of sovereignty by requiring states to align policies for overarching goals. This dynamic evokes debates around national interests versus collective responsibilities.
