Karl Lamprecht and his monumental work Deutsche Geschichte (1891-1909) caused one of the most important controversies (1891-1898/99) in the German historical profession, which led to a general reflection on the theoretical and methodological premises of the German science of history in the 19th century. In his Deutsche Geschichte, Lamprecht goes beyond the reigning paradigm of historicism and increasingly focuses on cultural history. The present thesis aims at investigating the intellectual influences and imprints which set the foundation for his cultural-historical approach. Additionally, his concept of history, as revealed in his work Deutsche Geschichte, is explored. In this context, the development stages of his concept of history in the view of the afore mentioned controversy are examined as well. For this purpose, Deutsche Geschichte is analyzed drawing on substantial secondary literature.With regard to findings, it has to be noted that Lamprechts concept of history has been decisively influenced by some of his university professors, especially Wilhelm Roscher, Jacob Burckhardt and Ernst Bernheim. Furthermore, it should be stated that his concept of history passes several development stages, which is primarily due to the Lamprecht controversy. In the first volumes of Deutsche Geschichte, which were published before the controversy, his conception of history differs from that exposed in the volumes afterwards: In the first volumes, Lamprecht strives for a cultural history considering material and ideal culture, but proclaims a dominance of material culture for historical development. After the controversy, Lamprecht turns towards a psychological perspective on history, which can be mainly attributed to the influence of Wilhelm Wundt.
