Blue Riband in the context of "SS Kaiser Wilhelm der Grosse"

The Cunard Line (/ˈkjuːnɑːrd/ KEW-nard) is a British shipping company and an international cruise line based at Carnival House at Southampton, England, operated by Carnival UK and owned by Carnival Corporation & plc. Since 2011, Cunard and its four ships have been registered in Hamilton, Bermuda.

In 1839, Samuel Cunard was awarded the first British transatlantic steamship mail contract, and the next year formed the British and North American Royal Mail Steam-Packet Company in Glasgow with shipowner Sir George Burns together with Robert Napier, the famous Scottish steamship engine designer and builder, to operate the line's four pioneer paddle steamers on the Liverpool–Halifax–Boston route. For most of the next 30 years, Cunard held the Blue Riband for the fastest Atlantic voyage. However, in the 1870s Cunard fell behind its rivals, the White Star Line and the Inman Line. To meet this competition, in 1879 the firm was reorganised as the Cunard Steamship Company Ltd, to raise capital.

RMS Lusitania was a British ocean liner launched by the Cunard Line in 1906 as a Royal Mail Ship. She was the world's largest passenger ship until the completion of her running mate Mauretania three months later. In 1907, she gained the Blue Riband appellation for the fastest Atlantic crossing, which had been held by German ships for a decade.

Though reserved for conversion as an armed merchant cruiser, Lusitania was not commissioned as such during WWI but continued a transatlantic passenger service, sometimes carrying war materials, including a quantity of .303 ammunition, in her cargo. The German submarine U-20 hit her with a torpedo on 7 May 1915 at 14:10, 11 miles (18 km) off the Old Head of Kinsale, Ireland, leading to her sinking about 18 minutes later. Only six of several dozen lifeboats and rafts were successfully lowered; there were 767 survivors out of the 1,960 people on board, while 1,193 perished.

SS Kaiser Wilhelm II was a Norddeutscher Lloyd (NDL) Kaiser-class ocean liner. She was launched in 1902 in Stettin, Germany. In the First World War she was laid up in New York from 1914 until 1917, when the US Government seized her and renamed her USS Agamemnon. In 1919 she was decommissioned from the Navy and laid up. In 1927 she was transferred to the United States Army, who renamed her USAT Monticello. She was scrapped in 1940.

When launched, Kaiser Wilhelm II was the largest ship registered in Germany. The weight of her hull and machinery was surpassed only by the British White Star Liners RMS Cedric and Celtic. She served NDL's transatlantic route between Bremen and New York. She won the Blue Riband in 1904. Her passengers included the composers Gustav Mahler in 1910 and Jean Sibelius in 1914.
