The term has therefore linked the history of European imperialism very closely to the legacy of the Roman Empire. Originally it meant little more than “sovereignty,” a sense it retained until at least the eighteenth century. Ever since the days of the Roman Republic, however, “empire” has also been a word used to describe government over vast territories. When, for instance, in the early first century A.D., the historian Tacitus spoke of the Roman world as an “immense body of empire,” he was alluding as much to its size as to its sovereignty, and ultimately it would be size that separated empires from mere kingdoms and principalities. In 1914, the great Norwegian polar explorer Fridtjof Nansen calculated that the Russian Empire had been expanding at an average daily rate of fifty-five square miles for over four centuries, or more than twenty thousand square miles per year, an area roughly the size of modern Belgium. In terms of territory the Russian Empire was the largest the world has ever known, although most of it was unoccupied. But similar sorts of figures could be conjured up for most other imperial peoples. Under Philip II, the father of Alexander the Great, the Macedonian monarchy ceased at the Aegean and the Black Sea.
