On an uncertain date speculatively identified with December 6, in either 1208 or (more usually attributed) 1209, the near-riotous townspeople of Oxford hanged two or three student “clerks” at that settlement’s famous university.
About this time, a certain clerk engaged in the liberal arts at Oxford killed a certain woman by accident and when he found that she was dead he decided to flee.
But when the mayor of the city and many others who had gathered found the dead woman they began to search for the killer in his house which he had rented together with three of his fellow clerks.
Not finding the man accused of the deed they seized his three fellow clerks who said they were wholly ignorant of the murder and threw them into prison; then a few days later they were, by order of the King of the English, in contempt of the rights of the church, taken outside the city and hanged.
When the deed had been done, both masters and pupils, to the number of three thousand clerks, left Oxford so that not one remained out of the whole university; they left Oxford empty, some engaging in liberal studies at Cambridge and some at Reading.
This ugly affair rooted in the ancient conflict between university and town caused much of the ancient academy‘s student population to flee town — some proceeding to found Oxford’s rival institution Cambridge. (This pdf short story on the Cambridge site dramatizes events.)
The conflict between the town and university at Oxford over this bloodletting persisted until 1214 when a Papal legate settled the dispute in favor of the university.
The authors of the hanging were required to carry the bodies to an honorable resting place, and the town was required to host a dinner for poor students once every year — on St. Nicholas‘s day, Dec. 6, which on that basis has become associated with the otherwise never-specified date of the unfortunate clerks’ demise.
