Britain, as an island nation founded on commercial trade, boasted countless good harbors nationwide, but during the medieval period, Britain's most important ports came from the southeast region. The representative cities were the founding ports of the Cinque Ports: Sandwich, Dover, Hythe, Romney, and Hastings.
The Cinque Ports, facing France across the English Channel, just a channel's breadth away and backed by the fertile plains of south-eastern England with their gentle coastlines easy to dock at, naturally became Britain's prime choice for foreign trade during the scientifically undeveloped Middle Ages.
By the time of the Renaissance, with the development of America, the rise of the slave trade, the merger of Ireland and the Kingdom of Great Britain, the onset of the first industrial revolution, and the expansion of Far East transshipment trade, the small fishing village of Liverpool in the southwest of Britain finally welcomed its golden age of development.
