Legal sovereignty refers to the ultimate authority of a state to govern itself without external interference. It means that a state has the power to create and enforce laws, manage its own affairs, and make decisions regarding its territory and population. This concept is fundamental in international law, as it establishes the framework for how states interact with one another. In practice, legal sovereignty allows a state to enter treaties, engage in diplomacy, and participate in international organizations like the United Nations. However, it can be challenged by factors such as colonialism, globalization, or human rights interventions, which may limit a state's autonomy in certain situations.
