While many empires had existed in the past, each having its own fair shares of landscape, like the Hittite Empire, Phoenicia, Carthaginian Empire, Roman empire, Mongolia empire, and British empire, the biggest empire to date is the British empire. At the peak of its power in 1913, the empire covered an astonishing 13.71 million square miles, a figure close to a quarter of the world's landmass, and has a population of 412 million spread across different regions living under the empire.
