World Back Then is a world history map that lets you explore different time periods in history as if you were on Google Maps.
The interactive map for a specific year shows at a glance what was the political situation in the world "back then" — countries, kingdoms, empires and other types of societies — providing contextual information. Click anywhere to get more information and follow links to external sources to go more in depth on a given topic.
A set of filters also allows showing information about different areas of knowledge like historic inventions, philosophy, arts, literature and so on. Filters are currently under development and will be added in future releases.
For more information about the sources of the information check the FAQ.
Q: Where is the information coming from?
All the content in this website comes from other open sources.
The only years available are those that are present in the original dataset for the historical state boundaries.
