The wreck of the RMS Lusitania / Roblox

RMS Lusitania (named after the Roman province in Western Europe corresponding to modern Portugal) was a British ocean liner that was launched by the Cunard Line in 1906 and held the Blue Riband appellation for the fastest Atlantic crossing in 1908. It was briefly the world's largest passenger ship until the completion of the Mauretania three months later. She was sunk on her 202nd trans-Atlantic crossing, on 7 May 1915, by a German U-boat 11 miles (18 km) off the western coast of Ireland, killing 1,198 passengers and crew.[2]

The sinking occurred about two years before the United States' declaration of war on Germany. Although the Lusitania's sinking was a major factor in building American support for a war, war was eventually declared only after the Imperial German Government resumed the use of unrestricted submarine warfare against American shipping in an attempt to break the Transatlantic supply chain from the US to Britain, as well as after the Zimmermann Telegram.
