Rankings

These lists answer the questions people actually search for — the bloodiest battle, the largest, the deadliest war — but without the false precision those lists usually carry. Each row shows the full low-to-high spread, the confidence grade behind it, and the sources it rests on. Battles and wars with no documented estimate are simply absent; nothing is imputed to fill a rank.

Every board is reproducible from the public open dataset — the ranking is just a sum and a sort over the CSVs. See the methodology for how the underlying figures are sourced.
