HistoryLayer draws the world as it was in any year from 123,000 BCE to 2026. Move the slider and the borders redraw for that year; the map carries 23,890 events, 12,790 people, 837 wars and 13,183 cities, each one readable in place. Signing in is optional and lets you keep what you find.

HistoryLayer is an interactive map of world history: pick any year from 123,000 BCE to 2026 and the borders, events and people of that moment are drawn for you. It needs JavaScript to draw the map. The guide, the sources and licences and the privacy page are readable without it.
