I've been wanting to do this for a while, after being inspired by Ollie Bye's "History of the World" video several years ago.

I'm not the first person to have done this - resources like OpenHistoricalMaps are amazing.

But, I noticed there were a few disparate datasets / academic databases online, so I combined them together as best as I could (I've linked all sources in the app). To make it more interesting, I also included:

- Notable events from the time period (geolocated where possible), sourced from wikidata

- Ancient cities + their original names

- Empire hierarchies for colonial empires like the British Empire

You can jump across time and use shuffle to explore some fascinating corners of history.

Would love any feedback, especially from people who like maps, timelines, and weird historical rabbit holes. Also please report any data issues if you find them (it's all using publicly collated data, so there will be plenty).

Happy to publish code / data on GH if there's interest!
