Globalization has introduced new and diverse challenges for the nation state not only in terms of managing rapid economic and cultural integration, but also with respect to governance and decision-making. Globalization, as a concept, contradicts the traditional understanding of the primacy of the nation-state in the world order and introduces a possibility for parallel existence of various non-state actors such as Intergovernmental organizations (IGOs) and International non-governmental organizations (INGOs). In recent decades, the growth of transnational groups - both political activist groups and dangerous terrorist organizations - also shows the ways in which modern technologies and globalization can challenge and possibly undermine the state’s ability to protect its borders and pursue its goals. In other words, the sovereign state has been continuously challenged, both internally and externally. Therefore, globalization has a serious influence on the concept of sovereignty, which is a basic element upon which the existence of the nation-state depends. The present paper examines how globalization has impacted nation states on various fronts.
