Historical Atlas

Centennia is the creator of the Centennia Historical Atlas, a desktop software atlas that brings a thousand years of European and Middle Eastern history to life through animated maps. Covering the period from 1000 AD to the present, the complete atlas tracks more than 9,000 border changes and illustrates major wars and territorial conflicts, showing political control at intervals as brief as five weeks. Users can zoom, move forward or backward through time, and consult linked events, explanatory text, a historical gazette, and a glossary. The maps emphasize control on the ground rather than only internationally recognized borders.

Centennia offers the free Nations Edition, which focuses on 1789–1939, and a full-access edition spanning the complete ten-century timeline. The software is available for Windows and macOS, with English, German, and Greek text options. For academic and institutional research, Centennia Research Edition provides historical vector and GIS data under paid licensing. The atlas serves individual history and map enthusiasts, genealogy researchers, schools, colleges, and universities, offering a visual way to explore changing nations, frontiers, and historical events.
