The German term for stock exchange, “Börse”, originated in the 15th century in Bruges, Belgium. Rich Italian merchants regularly gathered on the square “ter buerse” (lat. Bursa: bag, purse). At that time there was not yet a single currency. The countries were divided into many small economic areas, each with its own monetary system. This also applied to the German Reich with its many small states. The abundance of means of payment and the unrestricted exchange rates made usury and fraud possible.
