RMS Titanic was a British passenger liner that sank in the North Atlantic Ocean in the early morning of 15 April 1912 after colliding with an iceberg during her maiden voyage from Southampton, UK, to New York City, US.
A familiar picture â yet this is not the Titanic going down, but her lookalike, rival trans-Atlantic liner, Cunardâs RMS Lusitania, which sank off the Irish coast with the loss of 1,198 lives on 7 May 1915, three years after the Titanic went down.
