During the early nineteenth century, Europe were closely allied to the ideology of liberalism.In reference to economy this liberalism denotes freedom of market, less restrictions of state on the movement of goods and capitals. To get rid of these economic problems that was the main demand of the new emerged middle class. Existence of countless small principalities, different currencies, number of customs barriers created obstacles to economic exchange and growth for the new commercial classes. To sort out that problem Prussia including with most of the German states formed a customs union or Zollverein in 1834. The Zollverein abolished tariff barriers, reduced number of currencies, create network of railways for fast and heavy mobility. So a single solution for all these economic problems was known by the name of Zollverein.
