After the end of the Thirty Years' War, under the Treaty of Westphalia, Bremen ceded to Sweden much of its territory in the lowlands of the Weser. In 1810, Napoleon I declared Bremen the capital of the French department of Lippe. In 1813 the city was occupied by the Allies and at the Congress of Vienna Bremen was recognized as a free city of the German Union. Under the Treaty of 1856, special customs rules were established for Bremen, and in 1888 the city became part of the German Customs Union. In 1866, Bremen's troops took part in the hostilities of the Prussian army, and after the formation of the German Empire, Bremen became part of it as an independent free city with its own system of self-government.
