The Beginnings: From Slavic Stronghold to Trading Centre
The history of the city of Rostock is rooted in the early Middle Ages. The name originates from the Old Slavic word Rozstoc, meaning "widening of the river", and was first mentioned in 12th-century chronicles (circa 1161–1165). Initially, a fortified settlement of the Polabian Slavs stood on this site, which subsequently gave way to a German trading outpost.
Official Foundation and Growth Factors
A turning point in the city's destiny was the year 1218, when Prince Heinrich Borvin I officially confirmed the granting of Lübeck Law to the settlement. This event laid the legal foundation for Rostock's prosperity. Three key factors contributed to its rapid development:
- Strategic Geography: Its location at the wide mouth of the Warnow River provided ideal access to the Baltic Sea and protection from storms, which was critical for medieval navigation.
- Trade Potential: The city quickly became a transit point for the export of grain, herring, and renowned local brews to Scandinavia and Western Europe.
- Political Will: Local rulers actively attracted merchants and artisans from Westphalia and Saxony, accelerating the economic rise of the region, which is now part of modern Germany.
Early Layout: Unification of Three Towns
A unique feature of early Rostock was its fragmentation. In the 13th century, it developed as a conglomerate of three independent settlements — the Old, Middle, and New Town. Each had its own market square, town hall, and parish church. It was only in 1265 that these parts officially merged into a single entity, surrounding themselves with a common defensive wall. This unification consolidated resources and allowed the city to become one of the most influential members of the Hanseatic League.
