The present volume includes the fifth edition of General Political Science and the first issue of the first volume of Constitutional Law. The publication of these works in one volume is justified by the close relationship between General Political Science and Constitutional Law. For this reason, the two scientific branches constituted the content of the former chair of General Political Science and Constitutional Law at the Panteion University and constitute the content of the course of General Political Science and Constitutional Law, which is traditionally taught in the first two semesters of the Department of Public Administration. The fifth edition of the second issue of the first volume and the second volume of Constitutional Law are included respectively in the second and third volumes of this work. The "Fundamental Rights" constitute the third volume of this work.

In the first part of the work, General Political Science is presented. Political science is the science that deals with the state and is a branch of political science. General Political Science examines the phenomenon of the state in general, while Special Political Science deals with each specific state. General Political Science deals with the examination of the phenomenon of the state. According to the theory of legal personality, the state is a legal entity. The state, in the legal sense, is a people permanently settled in a certain territory (country) and organized as a legal entity exercising primary power. The combination of the theory of the three elements with the theory of legal personality gives rise to four conceptual elements of the state: people, territory (country), primary power, and legal personality.

Specifically, the work extensively analyzes the subject of General Political Science, the method of General Political Science, its relationship with political and legal science, the concept of the state, its genesis and abolition, the distinction and connections of the state, and its organs. In a separate chapter, the form of government of the state, the concentration and decentralization of state power, and the law are presented.

The second part includes the Introduction to Constitutional Law and examines the Organizational part of the Constitution. In this part, mainly Greek Constitutional Law is analyzed, and in particular, the current Constitution of Greece is systematically interpreted, taking into account the Constitutions of certain other contemporary states and especially those of the European Union. The term Constitutional Law is used with two meanings, with the meaning of the branch of law and with the meaning of the scientific branch that examines the rules of this branch. The term Constitution is used with two meanings: a) substantive and b) formal. Constitutional Law is the fundamental branch of Internal Public Law and includes the fundamental rules of organization and exercise of state power. Constitutional Law is the set of legal rules that determine the form of government, the highest main organs of the State, the manner of their emergence and their powers, and primarily the relations of state power with individuals subject to it. In other words, the object of Constitutional Law is the Constitution in a substantive sense. The rules of Constitutional Law are not included only in the Constitution in a formal sense (the constitutional text) but also in laws and customs.

The Constitution in a formal sense constitutes the core of Constitutional Law, which is why it took its name. The subject of Constitutional Law includes the following three topics: a) the form of government, b) the supreme (main) organs of the State, their election, powers, and the manner of their exercise, and c) the basic legal position of individuals vis-à-vis state authority. Of the three classical functions of the state (legislative, executive, and judicial), the first is the exclusive subject of Constitutional Law. The object of the scientific branch of Constitutional Law is the examination of the rules of Constitutional Law.

In separate chapters, the object of Constitutional Law, the Constitution and the Constituent Power, the sources of Greek Constitutional Law, the enactment and repeal of laws, the political system of Greece, the organization and exercise of state authority, the legislative function, the legislative position of the parliament and its members, the organization and functioning of the parliament, as well as the exercise of parliamentary control are analyzed. The main purpose of the work is educational, and for this reason, the history of the interpreted provisions of the Constitution and the bibliography are included in the footnotes.

In this 5th edition, updating has been carried out and recent case law has been included, as well as contemporary issues arising in relation to the subject matter of this book, as described above. It is a useful tool not only for students but also for practitioners of law.
