From overview
Starting on Thursday Dec 4, 2008, Wikimedia Commons witnessed a massive upload of new images. We received nearly 100,000 files from a donation from the German Federal Archives. These images are mostly related to the history of Germany (including the German Democratic Republic) and are part of a cooperation between Wikimedia Germany and the Federal Archives.
