The "Hans Kelsen Works" offer a comprehensive collection of writings by the significant jurist Hans Kelsen, which are central to the understanding of public law. Volume 12 contains the "General Theory of the State," a groundbreaking work that significantly influenced the Weimar debates on direction and methodology in the 1920s. Kelsen removes the methodological foundations from the general theory of the state and presents the first comprehensive representation of Pure Theory of Law. This edition is not only a historical document but also an indispensable reference work for students and professionals in the field of law. With 807 pages, the book provides in-depth insights into the concepts of the unity of state and legal order, as well as the fundamental norm. The publication is written in German and serves as a valuable resource for anyone interested in the foundations of public law.
