The University of Paris strike of 1229 was caused by the deaths of a number of students in punishing a student riot. The students protested with a "dispersion", or student strike, which lasted more than two years and led to a number of reforms of the medieval university. The event demonstrates the town and gown power struggles with the Church, secular leaders and the emerging student class and a lessening of local Church authority over the university. It was placed squarely under direct papal patronage, part of the program to centralise the Church structure that had intensified under Innocent III.
