The Reichstag was the Parliament of the North German Confederation (German: Norddeutscher Bund), founded after the Austro-Prussian War of 1866. It functioned until the establishment of the German Empire in 1871. Parliamentary sessions were held in the same building as the Upper House of the Prussian Landtag, the Prussian House of Lords, located at 3 Leipziger Straße in Berlin, Germany.
