The book offers a comprehensive exploration of the role of preambles in various political regimes and highlights the differences in their design. It is aimed at readers who wish to develop a deeper understanding of the interactions between constitutional texts and political ideals. With 641 pages, the work provides a well-founded and detailed examination of a often neglected yet central aspect of legal science.
