HMS Bulwark was one of five London-class pre-dreadnought battleships built for the Royal Navy at the end of the 19th century. The Londons were a sub-class of the Formidable-class pre-dreadnoughts. Completed in 1902 she was initially assigned to the Mediterranean Fleet as its flagship. The ship then served with the Channel and Home Fleets from 1907 to 1910, usually as a flagship. From 1910 to 1914, she was in reserve in the Home Fleet.

The British Mediterranean Fleet, also known as the Mediterranean Station, was a formation of the Royal Navy. The Fleet was one of the most prestigious commands in the navy for the majority of its history, defending the vital sea link between the United Kingdom and the majority of the British Empire in the Eastern Hemisphere. The first Commander-in-Chief for the Mediterranean Fleet was the appointment of General at Sea Robert Blake in September 1654. The Fleet was in existence until 1967.
