The Port of Rotterdam, also known as Europoort (Eurogate), has been an important trading center since approximately AD 1250. The history of the port reflects the evolution of the world’s economic base. Originally serving the North Sea herring fleets, it rapidly grew into a major mercantile port during the Dutch colonial period. The 19th century witnessed the Industrial Revolution, and steel and coal became major commodities passing through the port. Following the development of petroleum as a primary energy resource in the early 20th century, the port expanded westward to accommodate storage facilities and large oil tankers.
