Moving from the international studies on leisure policy and from “the rights to leisure” recognized in western Countries, the chapter analyses the relationship between the leisure policies adopted and the welfare system existing in a country, in order to propose an analytical model that includes some dimensions that we can apply to research on this theme. It also offers a historical approach for the study of leisure policies, a review of international declarations and conventions on leisure as a right for all the people, a reflection on the connections between welfare systems and leisure policies, looking at future challenges. Finally, a model for leisure policies classification is presented.
