As a history student, Marius concentrated on topics around the world, highlighting his passion for history from a panoramic, global point of view. At UCF, he wrote and presented papers that ranged in subject from the Progressive era in the U.S. to social issues in communist China during the time of Mao. Unlike his peers, Marius chose to focus his attention to subjects in Russian, Chinese, and Japanese history, as well as the history of antiquity. At the Freie Universität, Marius grew especially fond of the intellectual history of the Enlightenment and the sociopolitical history of postwar Germany.
