The Constitution of the German Confederation (German: Verfassung des Deutschen Bundes) or November Constitution (Novemberverfassung) was the constitution of the German federal state at the beginning of the year 1871. It was enacted on January 1, 1871. This is a slightly changed version of the Constitution of the North German Confederation; it is not to be confused with the constitutional laws of the German Confederation of 1815.
The Constitution of the German Confederation of 1871 incorporated agreements between the North German Confederation and some of the South German states that joined the Confederation: with Baden and Hesse-Darmstadt, but not Bavaria and Württemberg. The new constitution appeared on 31 December 1870 in the Bundesgesetzblatt des Norddeutschen Bundes (North German Federal Law Gazette) and came into effect the following day.
