converted to an armed merchant cruiser. In 1897, Norddeutscher Lloyd launched . She was followed three years later by three sister ships. The ship was both luxurious and fast, managing to steal the Blue Riband from the British. She was also the first of the fourteen ocean liners with four funnels that have emerged in maritime history. The ship needed only two funnels, but more funnels gave passengers a feeling of safety and power. In 1900, the Hamburg America Line competed with its own four-funnel liner, . She quickly obtained the Blue Riband for her company. This race for speed, however, was a detriment to passengers' comfort and generated strong vibration, which made her owner lose any interest in her after she lost the Blue Riband to another ship of Norddeutscher Lloyd. She was only used for ten years for transatlantic crossing before being converted into a cruise ship. Until 1907 the Blue Riband remained in the hands of the Germans. Early 20th century In 1902, J. P. Morgan embraced the idea of a maritime empire comprising a large number of companies. He founded the International Mercantile Marine Co., a trust which originally comprised only American shipping companies. The trust then absorbed Leyland Line and White Star Line. The British government then decided to intervene in order to regain the ascendancy. Although German liners dominated in terms of speed, British liners dominated in terms of size. and the Big Four of the White Star Line were the first liners to surpass Great Eastern as the largest passenger ships. Ultimately their owner was American (as mentioned above, White Star Line had been absorbed into J. P. Morgan's trust). Faced with this major competition, the British government contributed financially to Cunard Line's construction of two liners of unmatched size and speed, under the condition that they be available for conversion into armed cruisers when needed by the navy. The result of this partnership was the completion in 1907 of two sister ships: and , both of which won the Blue Riband during their respective maiden voyages. The latter retained this distinction for twenty years. Their great speed was achieved by the use of turbines instead of conventional expansion machines. In response to the competition from Cunard Line, White Star Line ordered the liners at the end of 1907. The first of these three liners, , completed in 1911, had a fine career,
