History created
a debt.
Sankofa makes it visible.
Sankofa is a public reparations calculator that models historical harm across countries, peoples, descendant communities, and states of responsibility.
What it does
Make historical responsibility visible.
Sankofa connects receiver communities, historical harms, and debtor states so that reparative responsibility can be explored openly rather than hidden inside disconnected histories.
