The University of Erfurt (German: Universität Erfurt) is a public university located in Erfurt, the capital city of the German state of Thuringia. It was founded in 1379, and closed in 1816. It was re-established in 1994, three years after German reunification. Therefore it claims to be both the oldest and youngest university in Germany. The institution identifies itself as a reform university, due to its most famous alumnus Martin Luther, the instigator of the Reformation, who studied there from 1501 to 1505. Today, the main foci centre on multidisciplinarity, internationality, and mentoring.
