Human Saga

An interactive atlas of world history.

Empires across deep time and the events that shaped them — scrub political borders year by year, from the first hominins to 2025.

Borders: open historical-basemaps (CC-BY-SA), loaded per year. Snapshots at set years — the slider steps between them.

About Human Saga

Human Saga is an interactive home for world history. Explore empires as duration bars on a shared deep-time axis, scrub a slider to watch political borders change across the centuries, and read sourced detail on every entry.

This is the production codebase (work in progress). It loads the project's real dataset — a globally balanced set of empires and events, each with cross-checked dates and ≥2 sources. The map borders come from the open historical-basemaps project.

See CLAUDE.md in the repo for the build plan and architecture.
