This made Italy the one country where there was a comparative abundance of gold and silver. Finally, during the Crusades, the Italian cities had become the point of embarkation for the Crusaders and had profiteered to an almost unbelievable extent.
And after the Crusades had come to an end, these same Italian cities remained the distributing centres for those Oriental goods upon which the people of Europe had come to depend during the time they had spent in the near east.
