Immanuel Kants probably counts as one of the most important European philosophers. In advance of his 300th birthday in 2024, in the context of the Kant Decade (since 2014), many activities have shed new light on several aspects of his work, but the importance of Kant's basis, Knigsberg, both town and Albertus university, has been widely neglected. This was the reason why the Historische Kommission fr ost- und westpreuische Landesforschung, the Ostpreuisches Landesmuseum, the Institut fr Kultur und Geschichte der Deutschen in Nordosteuropa and the Civic Museum in Lneburg organized an interdisciplinary conference in Lneburg in 2021 which is documented in the present volume. The articles discuss the importance of Kant for the theory of humaneness, his early years, the developments at the university of Knigsberg in the second half of the 18th century, as well as the later reception of Kant.
