The British Empire

In its Victorian heyday, when Britannia ruled the waves, the British Empire consisted of 58 countries with a population of 400 million. Covering 14 million square miles, or about a quarter of the earth's surface, it was seven times larger than the territories of Rome at their greatest extent. By then it was a far-flung but loosely-amalgamated assortment of dominions and dependencies that dwarfed its tiny base.
