The North German Confederation (German: Norddeutscher Bund) was the German federal state which existed from July 1867 to December 1870. Although de jure a confederacy of equal states, the Confederation was de facto controlled and led by the largest and most powerful member, Prussia, which exercised its influence to bring about the formation of the German Empire. Some historians also use the name for the alliance of 22 German states formed on 18 August 1866 (Augustbündnis). In 1870–1871, the south German states of Baden, Hesse-Darmstadt, Württemberg and Bavaria joined the country.
