Maps and competitions are strong tools to combine if you want people to interact with data. The project began by using geographic names and evolved into a more geo-historic frame, using Wikidata - always on the look for better ways of using data and accessing information, knowledge bases.
The Battles have been created by using wikidata query service, downloaded to PostGIS and rated. The rating was necessary in order to have a 'easy' and 'hard' questions mixture. Admittedly, labelling something 'easy' is highly idiosyncratic.
