It so happened that at the time of the downfall of the Roman Empire, or, as it is usually called, the beginning of the Middle Ages, another people of Semitic origin, the Jews, were for the most part engaged in international trade. There are records of Jewish merchants of that period shipping or exporting wine, oil, honey, fish, cattle, woolens, etc., from Spain to Rome and other Latin provinces, from Media to Brittannia, from the Persian Gulf and Ethiopia to Macedonia and Italy; there was no important seaport or commercial center in which the Jews did not occupy a commanding position. Their prominence as importers and exporters rather increased than diminished by the downfall of the great Empire. The new nations of the Germanic kingdoms which were founded on the ruins of Rome, knew nothing of international trade, and the position of the Jews as merchants was accepted by them as a matter of course. Hence the first traces of Jewish settlements in modern European countries are almost exclusively to be found in the earliest records of commerce and of trading privileges. They are then known as traders with distant countries, as sea-going men, as owners of vessels and as slave-traders. The commercial note or written obligation to pay, which is accepted in lieu of payment and is itself negotiable as a substitute for money, is a Jewish invention of those times. They developed industries and improved the material conditions of every place in which they were found in large numbers. As late as 1084, when their position had been already much weakened and the coming Crusades were casting their shadows, Bishop Rudiger of Speyer began his edict of privileges granted to the Jews with the statement: “As I wish to turn the village of Speyer into a city ... I call the Jews to settle there.” (See ibid. p. 351.)[1] THE SPANISH JEWS AS LAND OWNERS.
