During the age of the Hanseatic League from the 13th to 16th century, Hamburg was considered second only to the port and city of Lübeck in terms of its position as a central trading node for sea-borne trade. With discovery of the Americas and the emerging transatlantic trade, Hamburg exceeded all other German ports. During the second half of the 19th century, Hamburg became Central Europe's main hub for transatlantic passenger and freight travel, and from 1871 onward it was Germany's principal port of trade. In her time the Hamburg America Line was the largest shipping company in the world. Since 1888, the HADAG runs a scheduled ferry service across various parts of the port and the Elbe. The Free Port, established on 15 October 1888, enabled traders to ship and store goods without going through customs and further enhanced Hamburg's position in sea trade with neighbouring countries. The Moldauhafen has a similar arrangement, though related to the Czech Republic exclusively.
