From 1802 to the late 1980s, the Canary Wharf Estate was a part of Millwall, Limehouse and Poplar and was one of the busiest docks in the world. West India Docks was primarily developed by Robert Milligan (c. 1746–1809) who set up the West India Dock Company. After the 1960s, the port industry began to decline, leading to all the docks being closed by 1980.
