Souveraine is a term that refers to a sovereign or a ruler with supreme authority. It is often used in the context of monarchies, where a king or queen holds the highest power in a state. The concept emphasizes the independence and autonomy of a governing body or individual. In a broader sense, Souveraine can also relate to the idea of sovereignty in political theory, which involves the ultimate authority within a territory. This includes the ability to create laws, enforce them, and govern without external interference, making it a fundamental principle in discussions about statehood and governance.
