HMS Queen Mary was the last battlecruiser built by the Royal Navy before World War I. The sole member of her class, Queen Mary shared many features with the Lion-class battlecruisers, including her eight 13.5-inch (343 mm) guns. She was completed in 1913 and participated in the Battle of Heligoland Bight as part of the Grand Fleet in 1914. Like most of the modern British battlecruisers, she never left the North Sea during the war. As part of the 1st Battlecruiser Squadron, she attempted to intercept a German force that bombarded the North Sea coast of England in December 1914, but was unsuccessful. She was refitting in early 1915 and missed the Battle of Dogger Bank in January, but participated in the largest fleet action of the war, the Battle of Jutland in mid-1916. She was hit twice by the German battlecruiser Derfflinger during the early part of the battle and her magazines exploded shortly afterwards, sinking the ship.

Her wreck was discovered in 1991 and rests in pieces, some of which are upside down, on the floor of the North Sea. Queen Mary is designated as a protected place under the Protection of Military Remains Act 1986 as it is the grave of 1,266 officers and men.

Queen Mary, University of London (informally Queen Mary, QMUL or QM) is a public research university located in London, United Kingdom and a constituent college of the federal University of London. With roots dating back to 1785, Queen Mary was formed by the merger of four historic colleges, and since joining the University of London in 1915 has grown to become one of its largest colleges.

Queen Mary's main campus is located in the Mile End area of the East End of London, with other campuses in Holborn, Smithfield and Whitechapel. It has around 16,000 full-time students and 3,000 staff and had a total income of £297.1 million in 2010/11, of which £73.7 million was from research grants and contracts. Queen Mary is organised into three faculties – the Faculty of Humanities and Social Sciences, the Faculty of Science and Engineering and the Barts and The London School of Medicine and Dentistry – within which there are 21 academic departments and institutes.

HMS Queen Elizabeth (pennant number 00) was the lead ship of the Queen Elizabeth-class of dreadnought battleships, named in honour of Elizabeth I of England. She saw service in both World Wars. A Super-Dreadnought class of battleships, the HMS Queen Elizabeth vessels were the first British-built ships of their type to be powered by oil instead of immense amounts of coal.

She was launched on 16 October 1913 at Portsmouth, Hampshire, and entered service in January 1915 during World War I.

While still undergoing testing in the Mediterranean, the Queen Elizabeth was sent to the Dardanelles for the Allied attempt to knock the Ottoman Empire out of the war. The Queen Elizabeth was the only modern battleship to participate, though a number of battlecruisers and pre-dreadnought battleships were also involved. She became the flagship for the preliminary naval operations in the Dardanelles Campaign, leading the first line of British battleships in the battle of 18 March 1915. During the attempted military invasion of the Gallipoli on 25 April, the Queen Elizabeth was the flagship for General Sir Ian Hamilton, commander of the Mediterranean Expeditionary Force. However, after the sinking of HMS Goliath by a Turkish torpedo boat on 12 May, the Queen Elizabeth was immediately withdrawn to a safer position.
