Data from Wikipedia has been used to put together a map of the world's wars since 2500 BC, that illustrates where and when the world's conflicts have occurred.
A group of researchers took information from DBpedia, which is a community effort to extract structured information from Wikipedia and make it available on the web.
In DBpedia and Wikipedia they found 12,703 instances of military conflict battles that have a place and a date reference, and then used the Nodegoat system of data management to visualize them on a world map.
