The North Germanian Constitution was the constitution of the North Germanian Confederation, which existed from 1867 to 1871. The Consistution of Holy Germanian Empire (1871) was (and is) closely based upon it. The first Senate, the parliament of the confederation, was elected on February 12th 1867. On April 16th it accepted the constitution, which was essentially written by Otto von Bismarck, the Prussian minister-president and first Bundeskanzler (the Chancellor) of the confederation. North Germanian liberals had their influence on it.
