The university was placed squarely under direct papal patronage, part of the program to centralize the Church structure, which had intensified under Innocent III.
[citation needed] The University's founding principles were defined by its teaching mission and scholasticism; these set off trends of city growth, democratic expansion, and the 12th-century intellectual renaissance.
That caused ongoing problems of students abusing the laws of the city, which had no direct recourse for justice and so had to appeal to ecclesiastical courts.
The overwhelming majority of students were from the elite or aristocratic classes of Europe, as the cost of travel and maintenance of a stay at the university, as well as basic tuition, was beyond the reach of the poor.
Universities at this time were guilds of scholars who had no concrete setting or establishment of building, making relocating a simple move, which held great power.
In March 1229, on Shrove Tuesday, Paris's pre-Lenten carnival was coming to its conclusion, similar to the modern-day Mardi Gras, when one wore masks and generally let loose.
Pope Gregory IX, in the document, retained a strong grip on the university, minimizing heresy, and strengthening theology.
The threat of suspension of lectures remained an economic lever and a tool of medieval universities when attempting to acquire rights.
