Economic policy

Frederick did little to encourage economic development in Germany prior to the autumn of 1165. In that year he visited the lower Rhineland, the most economically advanced region in Germany. He had already travelled to northern Italy, the most economically advanced region in the Empire, three times. From 1165 on, Frederick pursued economic policies to encourage growth and trade. There is no question that his reign was a period of major economic growth in Germany, but it is impossible now to determine how much of that growth was owed to Frederick's policies.

The number of mints in Germany increased ninefold in the reign of Frederick and his son Henry, from about two dozen mints at the start of his reign to 215 mints in 1197 and from a mere two royal mints to 28. Frederick himself established at least twelve royal mints, including those of Aachen, Donauwörth, Ulm, Haguenau, Duisburg, Kaiserswerth, Frankfurt, Gelnhausen and Dortmund. He also granted privileges exempting the merchants of Aachen, Gelnhausen, Haguenau, Monza, Rome, Pisa and Venice from all tolls within the Empire.
