The RMS Titanic was an Olympic-class passenger liner owned by the White Star Line and built at the Harland and Wolff shipyard in Belfast, United Kingdom. For her time, she was the largest passenger steamship in the world.

On the night of 14 April 1912, during her maiden voyage, Titanic hit an iceberg and sank two hours and forty minutes later, early on 15 April 1912. The sinking resulted in the deaths of 1,517 people, making it one of the most deadly peacetime maritime disasters in history. The high casualty rate was due in part to the fact that, although complying with the regulations of the time, the ship did not carry enough lifeboats for everyone aboard. The ship had a total lifeboat capacity of 1,178 persons even though her maximum capacity was 3,547 people. A disproportionate number of men died also, due to the women-and-children-first protocol that was followed.

The Titanic used some of the most advanced technology available at the time and was, after the sinking, popularly believed to have been described as “unsinkable”.[4] It was a great shock to many that, despite the extensive safety features and experienced crew, the Titanic sank. The frenzy on the part of the media about Titanic's famous victims, the legends about the sinking, the resulting changes to maritime law, and the discovery of the wreck have contributed to the interest in and fame of the Titanic that continues to this day.
