In Leiden we are convinced that our scientific research makes an important contribution to a safe, healthy, sustainable, prosperous and just world.
Ever since the university's foundation in 1575, we have applied our efforts to developing, disseminating and applying scientific knowledge. Reflecting our motto, Bastion of Liberty, we aim to be a reliable authority in both scientific and societal debates.
Our research infrastructure, facilities and collections are world class. In those areas where we occupy a unique position nationally or internationally, we exercise particular care in our treatment of what may be at times vulnerable research areas and scientific-academic collections.
Much of our research focuses on making the unknown known and extending the boundaries of existing fields of research. Our research has a strong disciplinary basis within a very broad range of scientific fields. The university has thirty research institutes, located in both Leiden and The Hague, each of which conducts disciplinary and interdisciplinary research. Our researchers maintain close contacts with one another other and with society across the boundaries of their insitutes and faculties. They are guided by the highest ambitions of quality and integrity.
