In page Lübeck:

"

In the course of the war of the Fourth Coalition against Napoleon, troops under Marshal Jean Baptiste Bernadotte (who would later become King of Sweden) occupied Lübeck after a battle against Prussian General Gebhard Blücher on 6 November 1806 due to the latter's illegal use of the city as a fortress, in violation of Lübeck's neutrality, following the French pursuit of his corps after the Battle of Jena-Auerstadt. Under the Continental System, the State bank went into bankruptcy. In 1811, the French Empire formally annexed Lübeck as part of France but the anti-Napoleonic allies liberated the area in 1813.[citation needed]
