In this context, some major Theories are: The Decision Theory, The Power Theory, The Group Theory, The Systems Theory, The Political Culture Theory, The Political Cybernetic Theory, The Political Participation Theory, and The Political Development Theory.

Along with lucid and systematic elucidation of these Theories and Models, this Book contains an exposition of the Nature and Scope of Modern Political Analysis, its Limitations, and Contemporary Trends. It is intended to foster and reinforce the scientific foundation of the Discipline of Political Science.
