Both cosmopolitan thought and pacifism originate in ancient Greece and since the baroque century have been articulated with a perspective of international peace and the union of peoples in a world impacted by large-scale armed conflicts. This chapter aims to analyze from the cosmopolitan vision of peace in the international framework to the consolidation of a concept of positive peace as the human right to peace. A descriptive methodology from the qualitative paradigm has been used with a documentary and bibliographic approach. The importance of the study lies in the validity of the impact of peace from the cosmopolitan perspective according to the analysis of the processes referenced. It is mainly concluded that although the current transnational era is driven by market globalization and information and communication technologies, the notion of an open global village implies the deepening of the idea of cosmopolis so that the happy and peaceful coexistence among human beings can be realized.
