University of Rostock (Universität Rostock)

Rostock, Germany

The University of Rostock is not only the oldest university in the Baltic Sea region and one of the oldest universities in Germany. The ceremonial opening of the university with a Faculty of Law, a Medical Faculty and the Facultas Artium took place on 12 November 1419 at Rostock’s St. Mary’s Church. Magister Petrus Stenbeke from Erfurt was elected as rector. He enrolled 160 students. The University of Rostock consists of nine traditional faculties and an additionel Interdisciplinary Fa-culty. The Interdisciplinary Faculty unities scientists and students of all disciplines in four major departments: ‘Life, Light and Matter‘, ‘Maritime Systems‘, ‘Ageing of the Individuals and of Society‘, and ‘Knowledge – Culture – Transformation‘. These departments represent the key research areas that have developed throughout the long tradition of the University, and contribute to honing the University’s profile through connecting its strengths by means of interdisciplinary and cross-curricular cooperation.


13,323 students in total were enrolled at the University of Rostock in winter term 2018/19. And it was 4,186 university entrants in 2018. The share of international students is above eleven percent. 2,178 students successfully completed their studies. Offering more than 150 courses of study (37 bachelor degree courses, 60 master degree courses and 37 state examination courses including teaching degrees), the University of Rostock is one of Germany‘s Universities with the widest range of aca-demic subjects. Beyond that, its Centre for Teacher Taining and Educational Research conducts research on education and works on improving the quality of teacher training. (Source: University of Rostock)


The research presented in this video deals with the understanding of contracts and contract law. As MARKUS REHBERG explains, the main focus of contract law so far has been the moment of conclusion between the contracting parties, but a basic principle to fully comprehend the nature of contracts is still missing. He suggests to use the “justification principle”, outlined in the video, to solve this problem and explains how this new concept sheds light on the design of contracts.
