Context paragraphs:
SS Republic (1871): SS "Republic" was an ocean liner built in 1871 by Harland and Wolff for White Star Line.  It was intended to be the last of four vessels forming the Oceanic class, before two new ships were commissioned.  After a rough maiden voyage from Liverpool to New York City on 1 February 1872, the ship was chosen to be on White Star Line's first voyage on the South Atlantic and Pacific line with four other ships, destined for Chile.  In 1874, the construction of modern ships SS "Germanic" and SS "Britannic" led to SS "Republic"' s becoming the standby vessel of White Star Line.  It occupied this position for 15 years, and attempts were made to modernise it in 1888.  When SS "Teutonic" and SS "Majestic" entered service in the following year, the "Republic" became surplus to White Star's needs.

Black Star Line: The Black Star Line (1919−1922) was a shipping line incorporated by Marcus Garvey, the organizer of the Universal Negro Improvement Association (UNIA), and other members of the UNIA.  The shipping line was created to facilitate the transportation of goods and eventually African Americans throughout the African global economy.  It derived its name from the White Star Line, a line whose success Garvey felt he could duplicate.  Black Star Line became a key part of Garvey's contribution to the Back-to-Africa movement.  It was one among many businesses which the UNIA originated, such as the Universal Printing House, Negro Factories Corporation, and the widely distributed and highly successful "Negro World" weekly newspaper.

Royal Mail Steam Packet Company: 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.

SS Corinthic (1902): SS "Corinthic" was a British passenger ship, built in 1902 by Harland & Wolff and launched for the British shipping companies White Star Line and Shaw, Savill & Albion Line.  She was the second of the "Athenic"-class ocean liner s built for passenger and cargo service between Britain and New Zealand.  Her sister ships were  (1902) and  .  In 1931 "Corinthic" was decommissioned and scrapped.

SS Gallic: Two ships of the White Star Line have borne the name SS "Gallic", an adjectival reference to France:

Cunard-White Star Line: Cunard White Star Line, Ltd., was a British shipping line which existed between 1934 and 1949, It was created as an operating company to control the joint shipping assets of the Cunard Line and the White Star Line after both companies experienced financial difficulties during the Great Depression.  Cunard White Star controlled a total of twenty-five large ocean liners (with Cunard contributing fifteen ships and White Star ten).  Both Cunard and White Star were in dire financial trouble, and were looking to complete enormous liners: White Star had Hull 844 – RMS "Oceanic III" – and Cunard had Hull 534, which would later become  .

Robert Kermit Red Star Line: In 1818 the Red Star Line (also known as Red Star Packet Line, New Line, and Second Line) was founded by Byrnes, Trimble & Co. from New York.  (It should not be confused with the same-named Belgian/US-American shipping company Red Star Line, whose main ports of call were New York City and Philadelphia in the United States and Antwerp in Belgium).  On September 11, 1835 the line was bought by Robert Kermit from New York, a ship-owner and agent for packet ships, and was renamed Robert Kermits Red Star Line (aka Kermit Line).  In 1851 Robert Kermit took his brother-in-law Charles Carow into partnership as Kermit & Carow to carry on the business of general ship owning, commission and commercial trading.  Robert Kermit died in 1855 and Carow assumed the business.  In 1867 the Red Star Line went down.

American Line: The American Line was a shipping company founded in 1871 and based in Philadelphia.  It began as part of the Pennsylvania Railroad, although the railroad got out of the shipping business soon after founding the company.  In 1902, it became part of the International Navigation Co., with the American Line generally handling traffic between the United States ports of Philadelphia and New York City and the British ports of Liverpool and Southampton.  Sister company Red Star Line handled traffic between America and the European continent, primarily through Antwerp, Belgium.  The company's most prominent president was Clement Griscom, who led the company from 1888 to 1902 and worked as a company executive for its entire existence.  During its existence, the company was the largest American shipping company, rivalled only by the smaller, Baltimore-based Atlantic Transport Lines, although this distinction is a marginal one, as all American oceanic shipping concerns were dwarfed by British companies such as the White Star Line or Cunard Line and German ones such as HAPAG.

White Star Line: The Oceanic Steam Navigation Company or White Star Line of Boston Packers, more commonly known as just White Star Line, was a prominent British shipping company.

MV Britannic (1929): MV "Britannic" was a transatlantic ocean liner owned by White Star Line, and was the third company ship to bear the name.  Constructed by Harland and Wolff in Belfast, the ship was delivered to White Star Line in 1930 and assigned to the Liverpool-New York line.  When White Star Line merged with Cunard Line in 1934, the ship's route changed to the London-New York line, and she later provided winter Mediterranean cruises.
