The principle of self-determination in international politics asserts that peoples have the right to determine their own political status and pursue economic, social, and cultural development without external interference. This concept is significant in promoting independence and autonomy for nations and ethnic groups, particularly in the context of decolonization and national liberation movements. Self-determination challenges imperialism and supports minority rights, often serving as a basis for claims to independence or greater political representation. However, its application can also lead to conflicts, particularly when differing national identities or territorial claims are involved, complicating international relations.
