The history of the serious efforts to achieve chemical disarmament that culminated in the conclusion of the Chemical Weapons Convention (CWC) began more than a century ago. Although toxic chemicals have been used as a method of warfare throughout the ages, it is clear from some of the earliest recorded incidents that such weapons have always been viewed as particularly abhorrent. In this article a special attention will be paid to each part of the Convention itself, the main aim of the Convention which is the destruction of chemical weapons owned by the signatory states and the control of production, stockpiling and use of chemical for civil use as well. Any violation of the obligations, even inside a state territory, is punished with sanctions provided for in the Convention. The purpose of the article is to understand the obligations that the signatory states are required to observe, the inspection mechanism of specialized organizations, the possible sanctions in case of violations of the obligations verified after the inspections and the future perspectives after the global changes. In this paper the authors will analyze the creation and the evolution of CWC.
