Oceans, seas, and rivers provided places where people could fish and routes for transportation. Fish for food was very important; it was caught hundreds of miles out to sea, salted, and transported inland as a preserved product.

The sea was a trading route, and was an important route for conquest. It was the route preferred by many who went on crusades, and was the defining feature of the Hanseatic League, which traded through Northern Europe, and of such Italian cities as Venice and Genoa.

Transportation brought changes to the Middle Ages, as not just people, but ideas were moved about, which was an important effect of the crusades. The Hanseatic League and the Italian trading republics contributed greatly to the rise of the middle class.
