The geo-political entity known as Great Britain actually consists of a number of states united under a single crown. At its height, the British Empire controlled some 1/4th of the planet's landmass at some point or another, and it was said that the sun never set on the British Empire. (In fact the sun did set on the Empire, but only once, for 7.45 minutes, and resulted in a riot that has widely been miss-attributed to a controversial call during the 1879 Ashes). Today the Empire has been largely lost, having been replaced by a "commonwealth of nations." But only time will tell whether such a system will last, and the British will again take up the admirable job of protecting the world from itself in exchange for its natural resources and local labour.
