[Sidenote: Decay of Venice] Less rapid, but no less striking, was the decay of Venice and the other Italian cities. The first cargoes brought by the Portuguese from India caused the price of pepper and spices to fall to a degree which spelled ruin for the Venetians. The Turks continued to harry Italian traders in the Levant, and the Turkish sea-power grew to menacing proportions, until in 1571 Venice had to appeal to Spain for help. To the terror of the Turk was added the torment of the Barbary pirates, who from the northern coast of Africa frequently descended upon Italian seaports. The commerce of Venice was ruined. The brilliance of Venice in art and literature lasted through another century (the seventeenth), supported on the ruins of Venetian opulence; but the splendor of Venice was extinguished finally in the turbulent sea of political intrigue into which the rest of Italy had already sunk. EFFECTS OF THE COMMERCIAL REVOLUTION In a way, all of the colonizing movements, which we have been at pains to trace, might be regarded as the first and greatest result of the Commercial Revolution--that is, if by the Commercial Revolution one understands simply the discovery of new trade-routes; but, as it is difficult to separate explorations from colonization, we have used the term "Commercial Revolution" to include both. By the Commercial Revolution we mean that expansive movement by which European commerce escaped from the narrow confines of the Mediterranean and encompassed the whole world. We shall proceed now to consider that movement in its secondary aspects or effects. One of the first in importance of these effects was the advent of a new politico-economic doctrine—mercantilism--the result of the transference of commercial supremacy from Italian and German city-states to national states. [Sidenote: Nationalism in Commerce] With the declining Italian and German commercial cities, the era of municipal commerce passed away forever. In the peoples of the Atlantic seaboard, who now became masters of the seas, national consciousness already was strongly developed, and centralized governments were perfected; these nations carried the national spirit into commerce. Portugal and Spain owed their colonial empires to the enterprise of their royal families; Holland gained a trade route as an incident of her struggle for national independence; England and France, which were to become the great commercial rivals of the eighteenth century, were the two strongest national monarchies.
