RewindMap: interactive historical atlas
An interactive historical atlas to travel through thousands of years of history with a world map and a timeline, year by year.
RewindMap shows the world year by year: drag the timeline and the map changes to show what the territories looked like at each moment. It includes related events and stories, and layers you can adjust.
It works just as well for aimless browsing as for placing on the map an episode you have just studied or read about.
