RMS Titanic was a British passenger liner that sank in the North Atlantic Ocean on 15 April 1912 after colliding with an iceberg during her maiden voyage from Southampton, UK to New York City, US. The sinking of Titanic caused the deaths of more than 1,500 people in one of the deadliest peacetime maritime disasters in modern history. The RMS Titanic, the largest ship afloat at the time it entered service, was the second of three Olympic class ocean liners operated by the White Star Line, and was built by the Harland and Wolff shipyard in Belfast with Thomas Andrews as her naval architect. Andrews was among those lost in the sinking. On her maiden voyage, she carried 2,224 passengers and crew.

Under the command of Edward Smith, the ship's passengers included some of the wealthiest people in the world, as well as hundreds of emigrants from Great Britain and Ireland, Scandinavia and elsewhere throughout Europe seeking a new life in North America. The first class accommodation was designed to be the pinnacle of comfort and luxury, with an on-board gymnasium, swimming pool, libraries, high-class restaurants and opulent cabins. A wireless telegraph was provided for the convenience of passengers as well as for operational use. Though Titanic had advanced safety features such as watertight compartments and remotely activated watertight doors, there were not enough lifeboats to accommodate all of those aboard due to outdated maritime safety regulations. Titanic only carried enough lifeboats for 1,178 people—slightly more than half of the number on board, and one-third her total capacity.

After leaving Southampton on 10 April 1912, Titanic called at Cherbourg in France and Queenstown (now Cobh) in Ireland before heading westwards towards New York.[2] On 14 April 1912, four days into the crossing and about 375 miles (600 km) south of Newfoundland, she hit an iceberg at 11:40 pm ship's time. The glancing collision caused Titanic's hull plates to buckle inwards along her starboard side and opened five of her sixteen watertight compartments to the sea; the ship gradually filled with water. Meanwhile, passengers and some crew members were evacuated in lifeboats, many of which were launched only partly loaded. A disproportionate number of men were left aboard because of a "women and children first" protocol followed by some of the officers loading the
