Germany is traditionally a country organized as a federal state. After the dissolution of the Holy Roman Empire in 1806, the German-speaking territories of the empire became allied in the German Confederation (1815–1866), a league of states with some federalistic elements. After the Austro-Prussian War, Prussia led the Northern states into a federal state called the North German Confederation (1867–1870). The Southern states joined the federal state in 1870/71, which was consequently renamed the German Empire (1871–1918). The state continued as the Weimar Republic (1919–1933). Present-day Germany is a federal republic which combines the States of Germany.
