Heidelberg University (informally Heidelberg, German: Ruprecht-Karls-Universität Heidelberg; Latin: Universitas Ruperto Carola Heidelbergensis) is a public research university located in the town of Heidelberg, Baden-Württemberg, Germany. Founded in 1386 on instruction of Pope Urban VI, Heidelberg is Germany's oldest university and one of the world's oldest surviving universities. It was the third university established in the Holy Roman Empire.
Heidelberg has been a coeducational institution since 1899. The university consists of twelve faculties and offers degree programmes at undergraduate, graduate and postdoctoral levels in some 100 disciplines. Heidelberg comprises three major campuses: the humanities are predominantly located in Heidelberg's Old Town, the natural sciences and medicine in the Neuenheimer Feld quarter, and the social sciences within the inner-city suburb Bergheim. The language of instruction is usually German, while a considerable number of graduate degrees are offered in English.
