# Wars on Map

An interactive historical atlas: 740 war records from the Correlates of War
project covering 1816-2014, plus 23 Second World War battles and campaigns
mapped movement by movement on one continuous map and timeline.

Editorial rules: casualty figures are given as published ranges with their
sources, never as midpoints; geographic approximations are labelled as such;
external links are only given for sources this project has checked, and all
other references are cited as publications. Absence of a war from the atlas is
not evidence of peace — the source releases stop in 2007 and 2014.
