Knowledge of German provides access to a culture that for more than a millennium has been central to the history, economy, arts, and sciences not just of Europe but of Western civilization as a whole. In the contemporary world, German-speaking countries have Europe's strongest economies and are playing an increasingly important role in world affairs. More Americans claim German ethnicity than any other, and German-speaking immigrants and their descendants have had an enduring impact on the history and culture of the United States. UWMadison has been a leader in the field of German studies for more than a century. The university's libraries are remarkable for the depth and breadth of their German-language holdings.
