The
Royal Mail Steam Packet Company was a
British shipping company founded in London in 1839 by a
Scot, James MacQueen. The line's motto was
Per Mare Ubique (everywhere by sea). After good and bad times it became the largest shipping group in the world in 1927 when it took over the
White Star Line. The company was liquidated and its assets taken over by the newly formed Royal Mail Lines in 1932 after financial trouble and scandal; over the years RML declined to no more than the name of a service run by former rival Hamburg-Süd.
