The course introduces the basic concepts and relationships that underpin Social Policy, an interdisciplinary academic subject that explores the response of organised societies to social needs. The study of Social Policy requires the analysis of theoretical and empirical evidence emanating from a wide range of social sciences and disciplines such as sociology, economics, politics, history, philosophy, law, statistics, etc. The course includes two aspects. On the theoretical level, as an academic subject, it refers to the study, investigation and interpretation of Social Policy. At the applied level, as a field of social intervention, it refers to the formulation and practice of social policies. In this context, the subject matter of the courses is formed, where the concept and role of Social Policy, the principles and values of Social Policy, the fields of Social Policy, the history of the welfare state and the main factors of its development, models and theories of welfare, the role of ideology in Social Policy, basic concepts such as need, poverty, social rights, etc. are presented.
