ZOLLVEREIN
Zoll"ve*rein`, n. Etym: [G., from zoll duty + verein union.]
Definition: Literally, a customs union; specifically, applied to the
several customs unions successively formed under the leadership of
Prussia among certain German states for establishing liberty of
commerce among themselves and common tariff on imports, exports, and
transit.
Note: In 1834 a zollverein was established which included most of the
principal German states except Austria. This was terminated by the
events of 1866, and in 1867 a more closely organized union was
formed, the administration of which was ultimately merged in that of
the new German empire, with which it nearly corresponds
territorially.
