30 May, taking seat in Lauenburg upon Elbe. In the summer of 1803, the French occupants raised their first war contribution with 21,165 rixdollars alone levied in Bremen-Verden. In 1803, the Duchy of Bremen had 180,000 inhabitants and an area of 5,325.4 square kilometres, the Principality of Verden 1,359.7 square kilometres and 20,000 inhabitants in 1806, while Hadeln comprised 311.6 square kilometres and had about 14,000 inhabitants. In the autumn of 1805, at the beginning of the War of the Third Coalition against France (1805–1806) the French occupational troops left Hanover in a campaign against the Archduchy of Austria (End of the First French Occupation of Hanover, 1803–1805). British, Swedish and Russian coalition forces captured Hanover, including Bremen-Verden. In December, the First French Empire, since 1804 France's new form of government, ceded Hanover, which it didn't hold anymore, to Brandenburg-Prussia, which captured it early in 1806. But when the Kingdom of Prussia, after it had turned against France, was defeated in the Battle of Jena-Auerstedt (11 November 1806), the Privy Council of Hanover returned from Lauenburg to Hanover City for a month, only to have to flee again from the Second French Occupation of Hanover (November 1806-January 1810), including Bremen-Verden. In 1807 France replaced the Privy Council and the Hanoverian estates of the realm, as announced on 20 September, by its own occupational government, the Commission du Gouvernement () under Governor General , and further installed a subdelegate, Peter Christian Dodt, replacing Bremen-Verden's deputation (decision-taking body), however, allowing Bremen-Verden's government (executive body) to work on. Napoleon I especially confiscated the Hanoverian electoral demesnes in order to enfeoff veterans with them. He retained exclusive access to the domains and their earnings, when on 1 March 1810 he allowed his brother King Jérôme Bonaparte to incorporate Bremen-Verden into his short-lived Kingdom of Westphalia, forming its Département Nord, only to annexe Bremen-Verden to the French Empire with effect from 1 January 1811, forming the Arrondissement Stade in the Département Bouches-de-l'Elbe and several cantons in the Département Bouches-du-Weser. From Restitution to incorporation into Hanover in 1823 In 1813, the Duchies of Bremen and Verden were restored to the Electorate of Hanover, which transformed into the Kingdom of Hanover in 1814. Even though Bremen-Verden's status as a territory of imperial immediacy had become void with the end of the Holy Roman Empire in 1806, the Duchies were not right away incorporated in a real union
