The article deals with the differences of pre-global and post-global conceptualizations in political sciences. It investigates the functions of political concepts under the changes globalization caused to political systems, culture and ideology. The paper does not engage with the methodological debates on political concepts, or question the undeniable importance of certain political concepts, but rather it addresses some of the principal concepts for which globalization may be a useful concept with regard to their similarities and differences with the Cold War (...) era. Despite the variety of political concepts as a result of various development phases of society, models of governance and ideological impact to the political processes along centuries, the concepts of power and authority seem to be among those that have survived in terms of the consistency of their relevance. However, the conception of politics through power, authority and leadership has been re-dimensioned significantly under the post-global era. By contrast, although the concept of sovereignty has been one of the initial concepts in the landscape of contemporary politics for many centuries back, following the effects of globalization, it has reduced its relevance significantly. In this view, as a consequence, the article discusses as well as the reconfiguration of the concept of state in a post-global era marked by a period of advancing causes—both trans-border and transnational causes—promoted by post-sovereignty states. Under these circumstances the traditional debate regarding conflict versus cooperation in politics is one of the areas remaining within a status quo dimension in the dioptric view of both pre-global and post-global conceptualizations. With a contrastive methodological approach, the article as well analyzes the development and meaning of the concepts of political equality, justice and liberty as indispensable concepts in modern post-global political processes.
