Crusades
Thirty years later, chroniclers read the accounts of these processions and translated pueri as "children" without understanding the usage. So, the Children's Crusade was born. The resulting story illustrates how ingrained the concept of Crusading was in the people of that time— the chroniclers assumed that the pueri must have been Crusaders. In their innocence, they returned to the foundations of crusading characteristic of Peter the Hermit, and met the same sort of tragic fate.
