Crusader armies were remarkably genetically diverse, study finds

DNA research adds to evidence soldiers heading east struck up relationships with locals

Crusader armies were made up of people from remarkably genetically diverse backgrounds, hailing not just from western Europe but also much further east, according to a new study that gives unprecedented insight into the fighters' lives.

The Crusades to the Holy Land were spread over two centuries, with many Europeans heading east to fight, and others turning up to trade.
