F. Oppenheimer's System der Soziologie is a multivolume publication that contains a general sociology as a common basis for all social sciences; a theory of development; as well as specialized sociologies: sociology of the economy, of law, of the state, etc. Oppenheimer conceived sociology as a historically grounded universal science. Ibn Khaldun came into play in relationship with Oppenheimer's state theory. His approach directly built on Gumplowicz's “sociological state theory”. An overview on Oppenheimer's works shows that Ibn Khaldun was by no means the starting point of theorization on the state. We do not find any reference to him in an earlier publication, Der Staat (1912), that already contained the full elaboration of Oppenheimer's theory. Nevertheless, his reception of Ibn Khaldun is important: Ibn Khaldun was mobilized within the framework of a scholarly debate that was ongoing amongst European sociologists at the time, and whose key representative, Ludwig Gumplowicz, contributed significantly to his reception in the concerned period. In this context, Oppenheimer did not merely mention Ibn Khaldun in an encyclopaedic endeavor to present a complete overview on “precursors” of sociology, but as a representative and contributor to a theoretical approach which, Oppenheimer believed, they both shared.

弗朗茨·奥本海默 (Franz Oppenheimer) (1926)，《国家社会学》。(Die Eroberung) [国家的社会学理念（征服）]

F. Oppenheimer 的System der Soziologie是一本多卷出版物，包含作为所有社会科学共同基础的一般社会学；发展理论；以及专门的社会学：经济社会学、法律社会学、国家社会学等。奥本海默认为社会学是一门以历史为基础的普世科学。伊本·赫勒敦在与奥本海默的状态理论的关系中发挥了作用。他的方法直接建立在 Gumplowicz 的“社会学状态理论”之上。对奥本海默著作的概述表明，伊本·赫勒敦绝不是国家理论化的起点。我们在较早的出版物Der Staat中没有找到任何提及他的信息(1912)，其中已经包含了对奥本海默理论的完整阐述。尽管如此，他对伊本·赫勒敦的接待很重要：伊本·赫勒敦是在当时欧洲社会学家之间正在进行的学术辩论的框架内动员起来的，其主要代表 Ludwig Gumplowicz 在相关时期对他的接待做出了重大贡献。在这种情况下，奥本海默不仅在一部百科全书式的努力中提到了伊本·赫勒敦，以对社会学的“前体”进行全面概述，而且作为一种理论方法的代表和贡献者，奥本海默认为，他们都分享了这种理论方法。
