English military corps, popularly known as Beefeaters, the sovereign's bodyguard since the corps was founded by Henry VII in 1485. Its duties are now purely ceremonial. There are Yeomen warders at the Tower of London, and the uniform and weapons are much as they were in Tudor times. The nickname `Beefeaters' is supposed to have originated in 1669 when the Grand Duke of Tuscany ascribed their fine appearance to beef.
