This is an introductory module to the study of politics and it lays the foundation for understanding and explaining political phenomena. It also lays the foundation for postgraduate study of political science and its related disciplines. The module essentially exposes the first time student of politics to basic concepts of the discipline such as power, state, government, legitimacy and sovereignty. It will navigate you through the debate on the science or non-science of politics as a field of study, the different approaches to understanding political phenomena and producing knowledge that will help explain political behaviour at all levels of political organization such as the local, national, regional and global. The last part of the modules will help give an insight into how politics is a medium of social change. You will learn in the course of this module and the discipline as a whole that studying and understanding politics is important as everything in life is influenced by politics making some scholars conclude that life is politics and politics is life. No wonder, famous Greek philosopher, Aristotle once said that man/woman is a political animal by nature.
