United American Lines, the common name of the American Shipping and Commercial Corporation, was a shipping company founded by W. Averell Harriman in 1920. Intended as a way for Harriman to make his mark in the business world outside of his father, railroad magnate E. H. Harriman, the company was financed by the younger Harriman's mother, Mary Williamson Harriman. Entering into the shipping world with little experience, Harriman's United American Lines entered into agreements with Hamburg America Line (German: Hamburg Amerikanische Packetfahrt Actien Gesellschaft or HAPAG), which was determined to recover after the financial disaster that befell the German company as a result of World War I.2
