This essay explores the maritime migration network between Asia and America by way of Europe during the first half of the twentieth century. It pays particular attention to the maritime activity of ‘lascar’ seamen, and the movement of labour between Britain, America, India, China, and Hong Kong. It examines the changes that underwent the network over time, the quantities of migrants and their intended destinations, and the period of upheaval caused by each World War. It also examines the racial, social, political, and cultural factors that shaped British and US immigration policies during the period. It concludes by stating that the US was undoubtedly a primary destination for Asian labourers, despite the well-broatcast perils relating to wages, racism, nationalism, and subjugation.
