Chronas is a crazy project that should be of interest to all history buffs. It is a collaborative and interactive map of the entire world history. The idea is to include in a colossal chronological frieze all historical events, places and figures from prehistory to the present day. They're crazy these Romans …

Chronas is a web application that displays a historical map with no less than 50 million data points. The card continues to get richer every day as each registered user can participate and contribute (to the Wikipedia or Vikidia). The project has so far convinced just over six thousand enthusiasts who regularly enrich it. It's dizzying.
A mix of Open Street Map, Wikipedia and Google Earth.
The Chronas project maps 4000 years of world history (historical characters, events, cultures, … religions) on a map with links to related Wikipedia articles each time. This extraordinary map is enriched with many different markers such as people, battles, cities, castles, etc. All these elements can be linked to express a relationship between them.
Chronas also plans to complete each marker with multimedia boxes like videos, images or podcasts to create an even wider knowledge network.
On the map, you can navigate through the years using a cursor at the bottom of the screen that allows you to move around the timeline. You can also go to a specific year and then click on the icons shown to learn more about battles, characters and places.
The end result is unparalleled wealth. When you log in for the first time, this incredible map in world history offers you to choose from three types of displays depending on your hardware configuration and the quality of your connection.
It is better to favor a large screen and give yourself a little time to take charge to appreciate its full potential. Chronas has uploaded several videos to help users from this point of view.
The most modern event available is the war in Iraq, going back in time, we can reach the year 580 BC, with the Sicilian wars.
A free and collaborative interactive map of world history

The follow-up is ensured by a revision history system. He has previously registered. Users can also ask questions about specific articles and create collections of articles (called Epics) on topics.
Chronas' numbers make you dizzy. Judge it instead.

Chronas is constantly evolving, even though it already has more than 50 million registered points. The project is free and free.
