The exchange of goods between Europeans and Arabs also reintroduced the use of currency which in turn further facilitated and increased trade operations. In less than a couple of centuries, many European towns went from a subsistence economy (based on the production of the goods strictly needed in the community) to a mercantile economy in which cities produced vast amounts of wealth.
