The role of verification in international relations is liked with the urge to verify which is evident throughout human history. This study focused on the evolution of this role in light of political circumstances and technological progress. Several different approaches to verification can be identified – bilateral, regional cooperation, global arrangements, and individual national efforts. Moreover, several themes characterize the existing verification regimes. These issues – namely the sharing of intelligence, managing compliance questions, and the integration of different regimes – present themselves as the negotiating ground for future years. One of the important result of the paper is that it demonstrates how the concept of verification, once a contentious political instrument, is encompassing anew actors, new frameworks, new technologies, and new fields.
