People's Crusade
This part of the First Crusade was also known as the crusade of the "paupers", a term which in the Middle Ages indicated a status as impoverished or mendicant wards of the Roman Catholic Church. Peter organized and guided the paupers as a spiritually purified and holy group of pilgrims who would, supposedly, be protected by the Holy Ghost. It is also possible that the People's Crusade also included well-armed soldiers and nobles. (A list of known participants in Peter's army can be found at The Digital Humanities Institute.)
