Running Reality is an ambitious project that is attempting to build an interactive map and timeline of the rise and fall of nations throughout history. Currently, you can visit Running Reality and choose a date or range of dates on the timeline to see a map of nations around the world at that time. Alternatively, you can click on the map and see a timeline of events contributing to the rise and fall of a nation. The details on each event are scarce at this point, but it is an open project so you can register and add details to events in Running Reality.
Applications for Education
Running Reality has a page for class project contributions. Instead of just being passive consumers of information from Running Reality, students can contribute to the growth of the project to help future students visiting the site.
