In the intense partisanship, characteristic of the Middle Ages, the schism engendered a fanatical hatred noted by Johan Huizinga: when the town of Bruges went over to the "obedience" of Avignon, a great number of people left to follow their trade in a city of Urbanist allegiance; in the 1382 Battle of Roosebeke, the oriflamme, which might only be unfurled in a holy cause, was taken up against the Flemings, because they were Urbanists and thus viewed by the French as schismatics.
