Chapter I defines the hallmarks of the French republican tradition, presents its internal diversity, elaborates the doctrine of the Third Republic and the crisis of the political system built on its foundations. Chapter II is devoted to the shaping of de Gaulle's views under the influence of republican nationalism and recognition of the republic as a permanent form of the existence of France. The role de Gaulle played in the reconstruction of republican order during World War II and after liberation is discussed there, too. Chapter III includes an analysis of the concepts of the 1930s reformatory movement that inspired the founders of the Fifth Republic. Chapter IV is devoted to the original political vision offered by de Gaulle and the constitutional thought of Michel Debr and Ren Capitant, authors of the two systems shaping the Fifth Republic: rationalized parliamentarism and democratic republicanism. In this chapter, the author discusses the development of the Gaullian constitutional thought in the years 19471951 and devotes quite a lot of space to the criticism of the federal forms of European integration and its constitutional ramifications. In chapter V, the book describes the mode in which de Gaulle effectuated the political change in 1958 and elaborates on the fundamental tenets of the Fifth Republic Constitution. In the final chapter, the book offers an answer to the question about the Fifth Republic's vitality and still-perpetuated identity and discusses relationships between the Polish constitutional tradition and de Gaulle's political output. It underscores the universal values and benefits accruing from the studies on the origins and identity of the Fifth Republic Constitution.
