Political science is In same time old and young science. Old, if we have in mind politics as subject of research, and young if we think about institutions in which politics is only subject of research or education. Having in mind religion as subject of political science,s research, we can easily conclude that all books in early history of mankind, which were dedicated to political topics, had for the first subject religion. That is clear if we remember that firsts form of politicals organisations in old Babylon, Egypt and Israel... were inseparable connected with gods. Gods gave legitimacy to those states. But so political sciences institutions in generally so Politology of religion, or politologie des religions in French, was born late. The firsts subjects of research in politicals sciences institutions were: state, political regimes, political parties, theory of politics, political systems, etc. Religion was studied very rarely. Modern political science was born under influence of french intellectuals: Dederot, Rousseau, Voltaire etc. They considered that religion will disappear with education and development. Their compatriot Alexis de Tocqueville thought contrary to their prognosis. The time gave right to Tocqueville. In the second part of XX century when the world develompent was highest, religion maintained its position in big part of globe and became stronger in a lot of states. That created big challenge for political science. Many of politicals scientis started with research concerning influence of religion into politics. That create, as the first step, centers for research of relations among religion and politics as is “labaratoire RELIGION ET POLITIQUE at “Institute d'etudes politiques” in Paris or “L'Observatoire du Religieux” at “Institut d'etudes politique” in Aix en provence en France, and finally that created special scientific discipline among political sciencies which name is “Politology of religion” or “Politologie des religions” in french.
