The principle of self-determination holds great significance in international politics as it grants peoples the right to freely choose their political status and pursue their economic, social, and cultural development. This principle supports claims to independence and autonomy by various ethnic or national groups, often leading to secessionist movements in states. It aims to address past colonial injustices and recognizes the legitimacy of minority groups seeking greater representation. However, it can also create tensions within and between nations, as competing claims to self-determination sometimes conflict with established national borders and sovereignty rights.
