The University of Paris (French: Université de Paris), metonymically known as the Sorbonne (French: [sɔʁbɔn]), was the leading university in Paris, France, active from 1150 to 1970, with the exception between 1793 and 1806 under the French Revolution. Emerging around 1150 as a corporation associated with the cathedral school of Notre Dame de Paris, it was considered the second-oldest university in Europe. In 1970, following the civil unrest of May 1968, the university was divided into 13 autonomous universities.
