Data-driven insights into humanity's greatest catastrophes
DeathVault aggregates the death tolls of recorded history's deadliest events into a single comparable dataset. The charts below rank every documented event by estimated deaths, break the total down by category, and let you see how individual catastrophes compare in scale across thousands of years.
Each figure is a central estimate drawn from institutional and peer-reviewed sources; where scholars disagree, the number reflects the broad consensus rather than the highest claim. Totals are the sum of those central estimates, so they are best read as an order of magnitude, not a precise count.

Notes on the data
Comparing death tolls across eras is inherently imperfect. Ancient events rest on fragmentary records and modern demographic modelling, while recent events benefit from systematic record-keeping — so a 6th-century plague and a 20th-century war carry very different margins of uncertainty even when their estimates look similar.
Category totals can be dominated by a small number of extreme events: a single pandemic or world war can outweigh dozens of smaller entries. We show ranges on individual event pages so you can see the uncertainty behind each headline number.
