Built in 1905 by Alexander Stephen and Sons in Glasgow for the Allan Line of Canada. Commissioned as SS Virginian, she served the Allan Line, as a sistership to RMS Victorian from 1905 until 1920. In 1912, she was one of several ships in wireless radio communication with RMS Titanic, giving iceberg warnings, and at one point erroneous wireless messages had Virginian towing Titanic to Halifax, Nova Scotia and that all on board Titanic were safe. Such a report appeared in the Daily Mirror on 16 April 1912.
World War I
World War II
During wartime the Ship was used as a mercy ship to exchange civilian internees, POWs, and diplomats. Chartered by the American, British and French governments for a total of 14 voyages and transporting 18,160 individuals.  In March 1942 the ship was chartered by the U.S. State Department via an arrangement with the Nazis and other Axis powers, facilitated with the help of the Swiss and Swedish governments, to repatriate civilian internees and diplomats from both sides of the war.
Its first American east bound voyage, carrying Axis individuals, was from New York City, USA to Lisbon, Portugal on May 7, 1942. On May 22, 1942 she departed Lisbon for a west bound return trip carrying Allied individuals to New York arriving on June 1, 1942. She made one more American east bound voyage, to exchange more Axis individuals, to Lisbon, Portugal on June 3, 1942 from Jersey City, New Jersey, USA .   Her final west bound exchange mission from Lisbon to New York arrived in the United States on June 30, 1942. That would be her last exchange trip to Lisbon as the Nazi government cancelled all further trades.  On July 15, 1942 she left from New York City, USA to her home port in Gothenburg, Sweden carrying approximately 800 Axis nationals. 
She continued to serve the British and French as a repatriation mercy ship.
The Drottningholm carried Red Cross supplies for distribution to other nationals still in Japanese controlled territory. One Japanese national jumped overboard and drowned causing the exchange to be halted until an American offered to stay in captivity.
The Drottningholm was painted white with the name of the vessel in very large letters, the Swedish flag and the words "Sverige" (Sweden) and "Diplomat" painted prominently on port and starboard. She was fully illuminated so her markings could be easily viewed.
In September 1944 it was being used by the Red Cross to transport POW's and civilians being repatriated from Germany to the UK via Sweden, under the command of Captain John Nordlander. Another voyage in April 1945 docked in Liverpool that included 212 ex-interned Channel Islanders.:172-9
