About the project

The Marches of Napoleonbegan as an effort to make Napoleon's correspondence and campaigns explorable as a single, connected record — rather than scattered across archives and volumes of letters.

Every place on the map traces back to primary-source correspondence, cross-referenced against campaign records and residency research to build a picture of where Napoleon was, when, and who he was writing to.

Beyond the letters themselves, the map now indexes 16,042 individual days — his entire life from birth in Ajaccio to his death in exile — alongside a tactical layer for 117 named battles and a political-boundary layer covering 48 territories across Europe.

The project is built and maintained by ACTV Maps, on infrastructure hosted entirely within the EU/EEA.
