Fundamentals of Political Science: Theories and Approaches is conceived as a structured, student-centered textbook that introduces the core concepts, theories, ideologies, and institutional frameworks of Political Science in a clear and systematic manner. It is written to meet the needs of undergraduate learners who require conceptual foundations and postgraduate learners who need theoretical depth, analytical tools, and structured revision. The book is especially useful for interdisciplinary learners because it connects Political Science with Law, Governance, and Public Institutions, enabling students to understand how political concepts shape Legal Systems, State Authority, Public Policy, and Democratic Participation.
