The University of Paris (French: L'Université de Paris), metonymically known as the Sorbonne, was a French university, founded circa 1150 in Paris, France, recognised 1200 by King Philip II and 1215 by Pope Innocent III, as one of the first universities. It quickly became reputed for its academic performance especially in the domains of theology and philosophy, and introduced the system of student nations. The university is often referred to as the Sorbonne after its collegiate institution, Collège de Sorbonne, founded around 1257 by Robert de Sorbon.
