Rostock is the largest city in the north German state Mecklenburg-Vorpommern. Rostock is on the Warnow river; the district of Warnemünde 12 kilometres (7 miles) north of the city centre is directly on the Baltic Sea coast.
In the 11th century Polabian Slavs founded a settlement at the Warnow river called Roztoc (*ras-tokŭ, Slavic for "fork of a river"); the name Rostock is derived from that designation. In 1218, Rostock was granted Lübeck law city rights by Heinrich Borwin, prince of Mecklenburg. In 1251, the city became a member of the Hanseatic League. Rostock is home to one of the oldest universities in the world, the University of Rostock, founded in 1419.
The city territory of Rostock stretches for about 20 km (12 mi) along the Warnow to the Baltic Sea.
