The significance of state sovereignty in international politics lies in its foundational role in establishing the rules and dynamics of global relations. Sovereign states maintain the authority to govern themselves without external interference, which underpins legal frameworks and diplomatic negotiations. This principle allows nations to negotiate treaties, engage in trade, and manage conflicts while asserting their own interests. However, the increasing interdependence of states and the rise of international organizations poses challenges to traditional notions of sovereignty, prompting debates on how it can coexist with global governance.
