This great commercial league fully sustained the opinion—at least entertained at that period—that “Commerce alone is sufficient to insure greatness.” Subsequent events, arising out of the political elements of a country, afford convincing proofs that something more substantial than commerce is requisite to maintain the independence of any nation. This, however, is a question which involves that of the laws of nations and the ethics of political economy. Mr. Oddy ascribes the downfall of the Hanse Confederacy to their becoming warlike, and preferring political importance to wealth obtained by their original modes. It is, however, probable that no system of policy, either commercial or political, however wise or moderate, could have prevented the wars in which the Hanseatic League were involved. They stood on the defensive against their hostile neighbors, whose envy and jealousy were excited by the showy wealth of these cities. If commerce, therefore, brought on these wars, and defeated the great object of the league, it is evident that something more powerful than commercial sway was necessary to keep it in contact with the agricultural and political interests of the nation.[6] The combination of agriculture, manufactures, and commerce is no doubt the true cause of greatness,—the opulence and power of those nations who study the interest of each alike. It ought therefore to be the policy of the rulers to guard the progress of these great branches with the same fostering care and protection,—to encourage one without depressing the other; and to watch their reciprocal bearings, connection, and affinity, that the general interest may be promoted and the resources consolidated into a mass of strength adequate or superior to the power of their enemies. The United States has not lost sight of this fact; and hence every department of its great interests is alike defended, protected, and encouraged. We may have wars; but they will never arise from our neglect of any one particular branch of the government, or of its source of revenue. Perhaps no city in the world presented a greater display of wealth than did that of Bruges in the year 1301. She was one of the cities of the confederacy. It contained in that year sixty-eight companies of traders and artificers, while its citizens rivalled many of the European monarchs in their sumptuous mode of living. Some idea of their splendor may be formed from the following anecdote, recorded by Dr. Robinson in his “Historical Disquisitions,” who relates that, in the year 1301, Joanna of Navarre, the wife of Philip the Fair, of France, having been some days in Bruges, was so much struck with the splendor of the city and its grandeur, as well as the rich and costly dresses of the “citizen’s wives,” that she was moved by female envy to exclaim with indignation,—“I thought that I had been the only queen here; but I find that there are many hundreds more.”
