European University Viadrina Frankfurt (Oder) (German: Europa-Universität Viadrina Frankfurt (Oder)) is a university located at Frankfurt (Oder) in Brandenburg, Germany. It is also known as the University of Frankfurt (Oder). The city is on the Oder River, which marks the border between Germany and Poland. With 5,200 students — around 1,000 of whom come from Poland — and some 160 teaching staff, the Viadrina is one of Germany's smallest universities (only the University of Erfurt and Jacobs University Bremen have fewer students). The Latin word Viadrina means "belonging to, or situated at, the Oder River"; it derives from Viadrus, the name of a presumed river god of the Oder. Actually, an ancient name of the river is not documented, it is mentioned as Oddera in the 991 Dagome iudex referring to the realm of Prince Mieszko I of Poland. The Latin name was probably introduced by the Frankfurt scholar Jodocus Willich (c.1486–1552) and appeared in the Cosmographia by Sebastian Münster in 1544; the city of Frankfurt was known in Latin as Francofortum ad Viadrum.
