I made https://histori.city https://histori.city to be a wikipedia + maps mashup. the novel feature was adding a time range control so you can navigate the map in both space and across time. it's a work in progress, currently has a few tens of thousands of battles and city-foundings throughout history. it would be nice to remove google dependency and use OSM.
