Note 5 — I. GERMANY AT THE OUTBREAK OF THE REVOLUTION.
Reading edition
The "Zollverein" was the German Customs Union. It was originally founded in 1827, and largely extended after the war of 1866. Since the unification of Germany as an "Empire" in 1871, the States belonging to the Zollverein have been included in the German Empire. The object of the Zollverein was to obtain a uniform rate of customs duties all over Germany.
