After the Cold War, the international system was marked by the unparalleled supremacy of the United States, frequently referred to as a unipolar moment. In recent decades, however, this dominant position has come under increasing scrutiny due to changes in global power dynamics. This article investigates the diminishing dominance of the U.S. and the simultaneous emergence of a multipolar world order in the twenty-first century. The study employs a qualitative and theoretical methodology based on key international relations theories, especially realism, liberalism, and constructivism, to examine economic, military, political, and institutional indicators of hegemonic transition.Additionally, the paper investigates the rise of new power centers, including China, Russia, the European Union, and India, as well as the increasing influence of coalitions like BRICS and the Global South. It contends that the current phase signifies a gradual diffusion of power among multiple actors, resulting in a more intricate and contested global order, rather than a sudden collapse of American power. According to the study, the emergence of multipolarity offers both prospects and difficulties for global governance and international stability, making it essential for states and international institutions to develop adaptive strategies.
