Paris 1 Panthéon-Sorbonne University (French: Université Paris 1 Panthéon-Sorbonne), also known as Paris 1 (or Paris I) and Panthéon-Sorbonne University (or, together with Sorbonne University and Sorbonne Nouvelle University, simply as the Sorbonne), is a public research university in Paris, France.
It was created in 1971 from two faculties of the historic University of Paris – colloquially referred to as the Sorbonne – after the May 1968 protests, which resulted in the division of one of the world's oldest universities. Most of the economics professors (35 out of 41) of the Faculty of Law and Economics of Paris decided to found the multidisciplinary Paris 1 University with professors of the faculty of humanities of Paris and a few professors of law.
