Source-cited
Every figure, movement, and outcome traces to the primary evidence behind it.

Real entities and real citations only — no machine-generated summary pages.
Cross-linked
Wars, battles, factions, and commanders connect across every conflict in the atlas.
What you can do here
See the whole war — then trace it down to a single day’s fighting.
Every conflict opens onto a map you can read, a timeline you can scrub, and the sources behind every claim. Follow a war the way a strategist would — across ground, time, and consequence.
Read the ground
Battle nodes, campaign routes, and shifting front lines on one map. Toggle layers on and off to isolate exactly the movement you're tracing.
Move through time
One timeline scrubs from a war's turning points down to individual battles — so cause, decision, and consequence line up in the order they happened.
Check the evidence
Every figure and troop movement links back to its primary source. Open a war's dossier and verify the record yourself — nothing here is unsourced.

full-scale Russo-Ukrainian war
On 24 February 2022, Russia invaded Ukraine, starting the largest and deadliest war in Europe since World War II, in a major escalation of the existing war between the two countries that began when Russia attacked Ukraine in 2014. The fighting has caused hundreds of thousands of military casualties and tens of thousands of Ukrainian civilian casualties. As of May 2026, Russian troops occupy roughly 20% of Ukraine. From a population of 41 million, about 8 million Ukrainians have been internally displaced and 6–7 million have fled the country, creating Europe's largest refugee crisis since World War II.
