The principle of self-determination applies to independence movements by asserting that peoples have the right to decide their political status and pursue their economic, social, and cultural development. This concept is fundamental in international law and has been a driving force behind numerous decolonization efforts. Independence movements often invoke self-determination to gain legitimacy and support from the global community. Such movements can challenge existing borders and governance, impacting national and international relations, as aspirations for sovereignty collide with established states' interests.
