Who would dare to assert that Rome owed her universal empire to her geographical position? In the poor district of Latium, on the banks of a tiny stream emptying its waters on an almost unknown coast, where neither Greek nor Phenician vessel ever landed, except by accident, the future mistress of the world was born. So soon as the nations of the earth obeyed the Roman standard, politicians found the metropolis ill-placed, and the eternal city was neglected: even abandoned. The first emperors, being chiefly occupied with the East, resided in Greece almost continually. Tiberius chose Caprea, in the centre of his empire. His successors went to Antioch. Several lived at Trebia. Finally, a decree deprived Rome of the very name of capital, and gave it to Milan. If the Romans have conquered the world, it is certainly in spite of the locality whence issued forth their first armies, and not on account of its advantages. In modern history, the proofs of the correctness of my position are so abundant, that I hardly know how to select. I see prosperity abandoning the coasts of the Mediterranean, evidence that it was not dependent on them. The great commercial cities of the Middle Ages rise where no theorist of a preceding age could have predicted them. Novogorod flourishes in an almost arctic region, Bremen on a coast nearly as cold. The Hanse-towns of Germany rise in a country where civilization has scarcely dawned; Venice appears at the head of a long, narrow gulf. Political preponderance belongs to places before unknown. Lyons, Toulouse, Narbonne, Marseilles, Bordeaux, lose the importance assigned them by the Romans, and Paris becomes the metropolis--Paris, then a third-rate town, too far from the sea for commerce, too near it for the Norman barges. In Italy, cities formerly obscure, surpass the capital of the popes. Ravenna rises in the midst of marshes; Amalfi, for a long time, enjoys extensive dominion. It must be observed, that in all these changes accident has no part: they all are the result of the presence of a victorious and preponderating race. It is not the place which determines the importance of a nation, it is the nation which gives to the place its political and economical importance. I do not, however, deny the importance of certain situations for commercial depots, or for capitals. The observations made with regard to Alexandria and Constantinople, are incontestable.[80] There are, upon our globe, various points which may be called the keys of the world. Thus, it is obvious that a city, built on the proposed canal which is to pierce the Isthmus of Darien, would act an important part in the affairs of the world.
