The Presidential system of the United States represents one of the oldest and most influential political systems in the world, based on the principles of federalism and a clear division of powers into three independent branches: executive, legislative, and judicial. This structure stands out as crucial for understanding the dynamics of American politics often differing from parliamentary models of governance in that the President serves not only as a symbol of the state but also as the chief executive responsible for law enforcement, foreign policy leadership, and management of national resources. This paper provides a comprehensive insight into the organization, functions, and challenges of the U.S. presidential system, emphasizing its significance for domestic policy, international relations and shaping the American political landscape. The U.S. Presidential system, recognized as a global model, serves as an inspiration and example for many countries in organizing their governments. It is not merely a political model of one nation but a globally recognized exemplar that promotes stability. Its ongoing evolution and influence on the global political stage make it relevant for understanding and analyzing political systems worldwide.
