A federal system of government features a division of powers between national and regional authorities. This structure allows multiple levels of government to coexist, each with specific responsibilities and jurisdiction. Federal systems typically include a constitution that delineates the powers of each level, ensuring a balance of authority to prevent the overreach of power. Such arrangements can promote local governance and responsiveness to regional needs while maintaining national unity. Notable examples of federal systems include the United States and Germany, which exemplify how power-sharing can operate in diverse political contexts.
