Interactive Map Visualizes 1,469 Roman Battles from Founding to 1453 AD

Interactive Battle Visualization

An interactive map has been released that visualizes 1,469 Roman battles. Users can select a specific period or use a slider to view battles within any 25-year span, starting from the founding of Rome. The map allows for exploration of historical conflicts over a vast timeline.

Detailed Battle Information

Each battle location is represented by a dot, with its size indicating the number of battles fought there. Slices within the dot show the opponents involved, with grey representing civil wars. Sea battles are marked with diamonds, and dashed rings denote battles with only regional placement known. Zooming in or out merges or splits nearby dots, and hovering over a dot reveals battle details.

Comprehensive Records and Context

The map includes data on 1,469 battles with known results, excluding 236 civil-war battles and 4 with unknown outcomes. The Roman states are counted collectively, and battles with multiple opponents are counted against each. Users can select a row to access full records, including date, place, sides, commanders, Roman army details, sources, and reasons for doubtful entries. Results are color-coded for Roman wins (blue), draws (grey), or defeats (orange).

Inclusion Criteria and Historical Notes

The dataset includes named land or sea battles where a Roman force was a principal belligerent or distinct allied force, as documented in ancient and medieval historians or standard modern works. Sieges are counted if real fighting occurred. Unnamed skirmishes and massacres without a battle are excluded. The map also notes that traditional battles, particularly from the early Republic, are included as sources tell them, despite modern historical doubts.
