Every bar here is a catastrophe drawn to true scale — its length is the number of human beings it killed. Tap any for the breakdown: military and civilian dead, the cause, the cost, the outcome.
the journey continuesNext → Probability & OddsEach bar's length is the estimated number of people who died — drawn to true scale, so a single battle is a sliver beside a pandemic. Switch to Log to compare the smaller events without the giants swallowing them.
Historical death tolls are contested, and honestly so. Ancient figures rest on census gaps that may reflect administrative collapse as much as death; the indirect dead — from the famine and disease that follow war and conquest — usually dwarf those killed in combat, and are the hardest to count; and the borders of an "event" are fuzzy. Where scholars disagree, the figure shown is a defensible best estimate and the range is given. Treat every number as "our best reckoning," not a final word.
Modern pandemics from the WHO and IHME (COVID-19 excess mortality) and UNAIDS; war and disaster tolls from scholarly consensus and the standard comparative death-toll compilations. Figures are rounded to build intuition; if one is out of date, it's ours to fix.
This is a memorial rendered as a ruler — a way to feel magnitudes the mind can't hold. Each unit of length here was a person, with a life as whole as yours. It's built to inform and to remember, not to sensationalise.
