National sovereignty and state sovereignty, although similar, differ in focus. National sovereignty emphasizes the rights and autonomy of a population or ethnic group, often relating to their desire for self-determination and independence. In contrast, state sovereignty refers to the authority of a governing body over a defined territory and its ability to govern without external interference. While national sovereignty typically pertains to cultural or historical claims, state sovereignty is grounded in legal recognition within international law. These distinctions can lead to tensions, particularly in multicultural nations or regions with separatist movements.
