Though the articulations of a coast determine the ease with which maritime influences are communicated to the land, nevertheless history shows repeated instances where an exceptional location, combined with restricted area, has raised a poorly indented seaboard to maritime and cultural preeminence. Phoenicia's brilliant history rose superior to the limitation of indifferent harbors, owing to a position on the Arabian isthmus between the Mediterranean and the Indian Ocean at the meeting place of Europe, Asia, and Africa. Moreover, the advantages of this particular location have in various times and in various degrees brought into prominence all parts of the Syrian and Egyptian coasts from Antioch to Alexandria. So the whole stretch of coast around the head of the Adriatic, marking the conjunction of a busy sea-route with various land-routes over the encircling mountains from Central Europe, has seen during the ages a long succession of thriving maritime cities, in spite of fast-silting harbors and impeded connection with the hinterland. Here in turn have ruled with maritime sway Spina, Ravenna, Aquileia,[522] Venice, and Trieste. On the other side of the Italian peninsula, the location on the northernmost inlet of the western Mediterranean and at the seaward base of the Ligurian Apennines, just where this range opens two passes of only 1,800 feet elevation to the upper Po Valley, made an active maritime town of Genoa from Strabo's day to the present. In its incipiency it relied upon one mediocre harbor on an otherwise harborless coast, a local supply of timber for its ships, and a road northward across the mountains.[523] The maritime ascendency in the Middle Ages of Genoa, Pisa, Venice, and Barcelona proves that no long indented coast is necessary, but only one tolerable harbor coupled with an advantageous location.
Intermediate location between contrasted coasts.
Owing to the ease and cheapness of water transportation, a seaboard position between two other coasts of contrasted products due to a difference either of zonal location or of economic development or of both combined, insures commercial exchanges and the inevitable activities of the middleman. The position of Carthage near the center of the Mediterranean enabled her to fatten on the trade between the highly developed eastern basin and the retarded western one. Midway between the teeming industrial towns of medieval Flanders, Holland, and western Germany, and the new unexploited districts of retarded Russia, Poland, and Scandinavia, lay the long line of the German Hanseatic towns—Kiel, Lubeck, Wiemar, Rostock, Stralsund, Greifswald, Anclam, Stettin, and Colberg, the civitates maritimæ. For three centuries or more they made themselves the dominant commercial and maritime power of the Baltic by exchanging Flemish fabrics, German hardware, and Spanish wines for the furs and wax of Russian forests, tallow and hides from Polish pastures, and crude metals from Swedish mines.[524] So Portugal by its geographical location became a staple place where the tropical products from the East Indies were transferred to the vessels of Dutch merchants, and by them distributed to northern Europe. Later New England, by a parallel location, became the middleman in the exchanges of the tropical products of the West Indies, the tobacco of Virginia, and the wheat of Maryland for the manufactured wares of England and the fish of Newfoundland.
Historical decline of certain coasts.
Primitive or early maritime commerce has always been characterized by the short beat, a succession of middlemen coasts, and a close series of staple-places, such as served the early Indian Ocean trade in Oman, Malabar Coast, Ceylon, Coromandel Coast, Malacca, and Java. Therefore, many a littoral admirably situated for middleman trade loses this advantage so soon as commerce matures enough to extend the sweep of its voyages, and to bring into direct contact the two nations for which that coast was intermediary. This is only another aspect of the anthropo-geographic evolution from small to large areas. The decline of the Mediterranean coasts followed close upon the discovery of the sea-route to India; nor was their local importance restored by the Suez Canal. Portugal declined when the Dutch, excluded from the Tagus mouth on the union of Portugal with Spain, found their way to the Spice Isles. Ceylon, though still the chief port of call in the Indian Ocean, has lost its preëminence as chief market for all the lands between Africa and China, which it enjoyed in the sixth century, owing to the "long haul" of modern oceanic commerce.
Political factors in this decline.
Not only that far-reaching readjustment of maritime ascendency which in the sixteenth century followed the advance from thalassic to oceanic fields of commerce, but also purely local political events may for a time produce striking changes in the use or importance of coasts. The Piræus, which had been the heart of ancient Athens, almost wholly lost its value in the checkered political history of the country during the Middle Ages, when naval power and merchant marine almost vanished; but with the restoration of Grecian independence in 1832, much of its pristine activity was restored. Up to the beginning of the seventeenth century, Japan had exploited her advantageous location and her richly indented coast to develop a maritime trade which extended from Kamchatka to India; but in 1624 an imperial order withdrew every Japanese vessel from the high seas, and for over two hundred years robbed her busy littoral of all its historical significance. The real life of the Pacific coast of the United States began only with its incorporation into the territory of the Republic, but it failed to attain its full importance until our acquisition of Alaska, Hawaii, and the Philippines. So the coast of the Persian Gulf has had periods of activity alternating with periods of deathlike quiet. Its conquest by the Saracens in the seventh century inaugurated an era of intense maritime enterprise along its drowsy shores. What new awakening may it experience, if it should one day become a Russian littoral!
