Bremen-Verden


Bremen-Verden, formally the Duchies of Bremen and Verden, were two territories and immediate fiefs of the Holy Roman Empire, which emerged and gained imperial immediacy in 1180. By their original constitution they were prince-bishoprics of the Archdiocese of Bremen and Bishopric of Verden.
In 1648, both prince-bishoprics were secularised, meaning that they were transformed into hereditary monarchies by constitution, and from then on both the Duchy of Bremen and the Duchy of Verden were always ruled in personal union, initially by the royal houses of Sweden, the House of Vasa and the House of Palatinate-Zweibrücken, and later by the House of Hanover.
With the dissolution of the Holy Roman Empire in 1806, Bremen-Verden's status as fiefs of imperial immediacy became void; as they had been in personal union with the neighbouring Kingdom of Hanover, they were incorporated into that state.

Territory and insignia

The territory belonging to the Duchies of Bremen and Verden covered a rough triangle of land between the mouths of the rivers Elbe and Weser on the North Sea, in today's German federal states of Hamburg and Bremen. This area included most of the modern counties of Cuxhaven, Osterholz, Rotenburg upon Wümme, Stade and Verden, now in Lower Saxony; and the city of Bremerhaven, now an exclave of the State of Bremen. The city of Bremen and Cuxhaven did not belong to Bremen-Verden. The Land of Hadeln, then an exclave of Saxe-Lauenburg exclave around Otterndorf, was not part of Bremen-Verden until 1731. Stade was the capital.
Bremen-Verden's coat of arms combined the arms of the Prince-Bishopric of Verden, a black cross on white ground, with those of the Prince-Archbishopric of Bremen, two keys crossed ), the symbol of Simon Petrus, the patron saint of Bremen.

History

At the beginning of the Thirty Years' War the predominantly Lutheran Prince-Archbishopric of Bremen maintained neutrality, as did most of the Protestant territories in the Lower Saxon Circle, a fiscal and military subsection of the Holy Roman Empire. The neighbouring Prince-Bishopric of Verden also tried to maintain neutrality, but, being part of the Lower Rhenish-Westphalian Circle, which was troubled by confrontation between Calvinist, Catholic and Lutheran rulers and their territories, Verden soon became involved in the war.
In 1623 Verden's cathedral chapter, consisting mainly of Lutheran capitulars, elected Frederick II, Administrator of the Prince-Bishopric of Verden to be the ruler of the bishopric. Since he was Lutheran, the Holy See denied him the title of bishop. Nevertheless, he and later administrators were often referred to as prince-bishops. Frederick II was a son of King Christian IV of Denmark and Norway.
In 1626, Christian IV, who was also Duke of Holstein, and thus a vassal of the Emperor, joined the anti-imperial coalition of the Republic of the Seven United Netherlands and the Kingdom of England under James I. After Christian IV was defeated at the Battle of Lutter am Barenberge, on 27 August 1626, by the troops of the Catholic League under Johan 't Serclaes, Count of Tilly, he and his remaining troops fled to the Prince-Archbishopric of Bremen and set up headquarters in Stade. Administrator John Frederick, Duke of Schleswig-Holstein-Gottorp, who was also Administrator of the Prince-Bishopric of Lübeck, fled to Lübeck and left the Prince-Archbishopric to be ruled by the Chapter and the Estates.
In 1626, Tilly and his Catholic League troops occupied Verden, causing the Lutheran clergy to flee. He demanded that the Chapter of Bremen allow him to enter the Prince-Archbishopric and while the Chapter declared its loyalty to the Emperor, it delayed an answer to the request, arguing that it had to consult in a diet with the Estates, which would be a lengthy procedure.
Meanwhile, Christian IV arranged for Dutch, English and French troops to land in Bremen. The Chapter's pleas for a reduction of the contributions, Christian IV commented by arguing once the Leaguists would take over, his extortions will seem little.
In 1627, Christian IV withdrew from the Prince-Archbishopric of Bremen, in order to fight Wallenstein's invasion of his Duchy of Holstein. Tilly then invaded Bremen and captured its southern parts. The city of Bremen shut its city gates and entrenched behind its improved fortifications. In 1628, Tilly besieged Stade with its remaining garrison of 3,500 Danish and English soldiers. On May 5, 1628 Tilly granted them safe-conduct to England and Denmark-Norway and the whole of ecclesiastical Bremen was in his hands. Now Tilly turned to the city of Bremen, which paid him a ransom of 10,000 rixdollars in order to save itself from a siege. The city remained unoccupied.
The populations in both prince-bishoprics were subjected to measures of "re-Catholicisation" within the scope the Counter-Reformation, with Lutheran services suppressed and Lutheran pastors expelled. In July 1630, Tilly and most of the Catholic occupants were withdrawn, since on June 26 Gustavus Adolphus of Sweden had landed with 15,000 soldiers at Peenemünde, opening a new front in the Thirty Years' War. He had been won by French diplomacy to join a new anti-imperial coalition, soon also joined by the United Netherlands.
In February 1631 John Frederick, the exiled Lutheran Administrator of the Prince-Archbishoprics of Bremen and Lübeck conferred with Gustavus II Adolphus and a number of Lower Saxon princes in Leipzig, all of them troubled by Habsburg's growing influence wielded by virtue of the Edict of Restitution in a number of Northern German Lutheran prince-bishoprics. John Frederick speculated to regain the Prince-Archbishopric of Bremen and therefore in June/July 1631 officially allied himself with Sweden. For the war being John Frederick accepted Swedish overlordship, while Gustavus Adolphus promised to restitute the Prince-Archbishopric of Bremen to its exiled elected Administrator.
In October, an army newly recruited by John Frederick started to reconquer the Prince-Archbishopric of Bremen and — supported by Swedish troops — to capture the neighboured Prince-Bishopric of Verden, de facto dismissing Verden's intermittent Catholic Prince-Bishop Francis of Wartenberg who ruled 1630–1631, and causing the flight of the Catholic clergy wherever they arrived. The Prince-Bishopric of Verden was then subjected to Swedish military administration.
The reconquest of the Prince-Archbishopric of Bremen, helped by forces from Sweden and from the city of Bremen, was completed by May 10, 1632. John Frederick was back in his office, only to realise what Swedish supremacy meant. The Prince-Archbishopric of Bremen continuously suffered from billeting and alimenting soldiers. The relation between the Estates, who had to maintain administration under Catholic occupation, and the returned Administrator were difficult. The Estates preferred to directly negotiate with the occupants, this time the Swedes.
After John Frederick's death in 1634 Chapter and Estates regarded the dismissal of the Danish Prince Frederick as coadjutor bishop by Emperor Ferdinand II by virtue of the Edict of Restitution illegitimate. But the Swedish occupants had to be persuaded first, to accept Prince Frederick's succession. So Chapter and Estates ruled the Prince-Archbishopric until the conclusion of the negotiations with Sweden. In 1635, he succeeded as Lutheran Administrator Frederick II in the sees of Bremen and of Verden. But he had to render homage to the minor Queen Christina of Sweden.
In 1635–1636 the Estates and Frederick II agreed with Sweden upon the prince-bishoprics' neutrality. But this didn't last long, because in the Danish-Swedish Torstenson War of 1643–1645 the Swedes seized de facto rule in both prince-bishoprics. Christian IV of Denmark and Norway had to sign the Second Peace of Brömsebro on August 13, 1645, and a number of Danish territories, including the two Swedish occupied prince-bishoprics, were ceded into Swedish hands. So Frederick II had to resign as Administrator in both prince-bishoprics. He succeeded his late father on the Danish throne as Frederick III of Denmark in 1648.
With the impending enfeoffment of the military great power of Sweden with the Prince-Archbishopric of Bremen, as under negotiation for the Treaty of Westphalia, the city of Bremen feared falling under Swedish rule as well. Therefore, the city beseeched an imperial confirmation of its status of imperial immediacy from 1186. In 1646 Emperor Ferdinand III granted the Free Imperial City of Bremen the requested confirmation.

Transformation of prince-bishoprics into Bremen-Verden in 1648

The political entities of the Prince-Archbishopric of Bremen and the Prince-Bishopric of Verden were transformed by the Peace of Westphalia in 1648 into the Duchy of Bremen and the Principality of Verden, however, colloquially the Duchies of Bremen and Verden, without changing the territories' status of imperial immediacy and imperial estate. Every imperial estate, thus Bremen and Verden separately, was represented in the Diet of the Holy Roman Empire. The formerly Free Imperial City of Verden upon Aller was mediatised by the Peace of Westphalia and incorporated into the Duchy of Verden.
The two neighbouring territories could not unite in a real union without finding support by the Emperor and a majority among the imperial estates, which never happened. They were parts of two different imperial circles. From 1500 on the Prince-Archbishopric of Bremen and thus its successor Duchy of Bremen belonged to the Saxon Circle, a fiscal and military substructure of the Empire. The Prince-Bishopric of Verden and thus its successor, the Duchy of Verden, on the other hand, belonged to the Lower Rhenish-Westphalian Circle.
The Holy Roman Empire's taxes were collected and armies recruited and financed along the lines of the imperial circles. Bremen and Verden sent their representatives to the circle diet of their respective imperial circle. The circle diet decided how to share the burden of the taxes to be levied among the member territories. Thus Bremen and Verden even conflicted on the border between each other — i.e. on who may levy taxes where — which were not solved, even though the two fiefs were ruled in personal union by Sweden.
Emperor Ferdinand III at first enfeoffed the Queen regnant Christina of Sweden and her legal heirs with the duchies, as Sweden's reward from its participation in the Thirty Years' War. Bremen-Verden provided Sweden a strategic advantage, because it would participate with them in recruiting and financing armies in two imperial circles already covering all of the northern and north-western parts of the Holy Roman Empire, with Swedish Pomerania, a member in the Upper Saxon Circle, covering the Empire's North East.

Personal union with Sweden (1648–1712) and under Danish occupation (1712–1715)

The Swedes installed a new authority, Bremen-Verden's General Government, and chose Stade to be the new seat of government, with Bremervörde being the former Bremian capital, and Rotenburg upon Wümme being the former capital of the Prince-Bishopric of Verden.
The Swedish takeover in 1648 became a milestone for Bremen-Verden's interior constitution. Bremen-Verden turned from two elective monarchies into a hereditary double monarchy, with a personal rule of the or administrator exchanged for a viceregent government bound by Swedish instructions. The lax administrative structures were replaced with strictly hierarchic authorities with fixed competences. The co-rule of the Estates was curtailed. Bremen and Verden declined from independent territories of imperial immediacy to a collectively governed dominion of a European great power with all the pertaining restrictions and opportunities.
For her new fief, the Duchy of Bremen, the Queen regnant Christina of Sweden, ruling between 1644–1654, from 1648 on simultaneously Duchess of Bremen and Verden, sought after annexing the Free Imperial City of Bremen for it would be an important taxpayer. Earlier the city of Bremen had de facto participated in the Diets of the Prince-Archbishopric of Bremen. The latter's successor state, the Swedish Duchy of Bremen, tried to regain the city, arguing the Treaty of Westphalia named the city of Bremen as part of the to-be-established Duchy.
As Duchess of Bremen and Verden Christina of Sweden installed her residence in the former Benedictine. She abolished witch-burning in Bremen-Verden. In 1650 Charles Gustav, Hereditary Duke of the Palatinate of Zweibrücken-Kleeburg, since 1649 declared and 1650 recognised heir to the Swedish throne and thereby simultaneously to Bremen-Verden's dukedoms, came to Stade for interlocutions of unknown content. In 1650 the Lutheran clergy was subjected to a consistory, the new leading body after there was no Prince-Archbishop or Prince-Bishop anymore.
As to pastoring the tiny Catholic diaspora in Bremen-Verden the Holy See established apostolic vicariates.
Bremen-Verden's Swedish government tried to militarily defeat the Free Imperial City of Bremen, provoking two wars. In 1381 the city of Bremen had captured de facto rule in an area around Bederkesa and westwards thereof up to the lower Weser stream near Lehe. Early in 1653 Bremen-Verden's Swedish troops captured Lehe. In February 1654 the city of Bremen achieved that the Emperor granted it a seat and the vote in the Holy Roman Empire's Diet, thus accepting the city's status as Free Imperial City.
Ferdinand III ordered Queen Christina of Sweden, who was his vassal as Duchess, to compensate the city for the damages caused and to restitute Lehe. When in March 1654, the city started to recruit soldiers in the area of Bederkesa, in order to prepare for further arbitrary acts by Swedish Bremen-Verden, the latter's Governor General, Hans Christoffer von Königsmarck enacted the First Bremian War, arguing to act in self-defence. The Free Imperial City of Bremen had meanwhile urged Ferdinand III for support.

In July 1654, the Emperor ordered his vassal, as Duke, Charles X Gustav of Sweden, who had succeeded Christina after her abdication, to cease the conflict, which resulted in the in November 1654. This treaty left the main issue, accepting the city of Bremen's imperial immediacy, unresolved. But the city agreed to pay tribute and levy taxes in favour of and cede its possessions around Bederkesa and Lehe to Swedish Bremen-Verden.
Sweden and Swedish Bremen-Verden protested sharply, when in December 1660 the city council of Bremen rendered homage to Leopold I, Holy Roman Emperor. In 1663, the city gained seat and vote in the Imperial Diet, strongly opposed by the representatives of the Swedish Duchies of Bremen and Verden therein. In March 1664, the Swedish Diet came out in favour of waging war on the Free Imperial City of Bremen. Right after, Leopold I, busy with wars against the Ottoman Empire, had enfeoffed the minor King Charles XI of Sweden with Bremen-Verden, and with the neighbouring Brunswick and Lunenburg being paralysed by succession quarrels and France being not opposed, Sweden started from its Bremen-Verden the Second Bremian War.
The siege of the city by the Swedes under Carl Gustaf Wrangel brought Brandenburg-Prussia, Brunswick and Lunenburg, Denmark-Norway, Leopold I and the United Netherlands to the scene, all in favour of the city, with Brandenburgian, Brunswickian, Danish and Dutch troops at Bremen-Verden's borders ready to invade. So Sweden had to sign on 15 November 1666 the Treaty of Habenhausen, obliging it to destroy the fortresses built close to Bremen while banning the Free City of Bremen from sending its representative to the Diet of the Lower Saxon Circle. From Bremen-Verden, no further Swedish attempts to violently capture the city sprang out. Asked in 1700 what to do by Charles XII of Sweden, Bremen-Verden's General Government recommended to concede Bremen's status as a Free Imperial City.
A Danish attempt to conquer Bremen-Verden during the Dano-Swedish War failed. But the Danish threat to Bremen-Verden turned more virulent in 1667. In that year the local branch of the House of Oldenburg ruling in the County of Oldenburg, adjacent to Bremen-Verden's western border, died out with Anton Günther, Count of Oldenburg and Delmenhorst. Therefore, Christian Albert, Duke of Schleswig and Holstein at Gottorp inherited the county, but ceded it to his father-in-law Frederick III, King of Denmark and Norway, Administrator of the Prince-Archbishopric of Bremen and the Prince-Bishopric of Verden from 1635 until he had been expelled by the Swedish occupants in 1645.
So the Danes ruled territories clung around Bremen-Verden at its northern and western border. Both powers entered into a dangerous competition for the exclusive opportunity to levy the lucrative tolls from ships heading for Hamburg and Bremen, with the former at that time being a ducal Bremian and the latter a comital Oldenburgian privilege.
After a stay in Hamburg with the administrators of her Swedish estates, and his son, in order to reorganise her revenues, in 1668 Christina of Sweden, stopped by in Stade on her way home to Rome.
The rise of Swedish centralisation and absolutism found its way partially into Bremen-Verden's practise. Bremen-Verden wasn't streamlined as to its jurisdiction and its military system, but the latter strictly subjected to Stockholms generalty. Especially in jurisdiction, Bremen-Verden's Estates maintained their stake. But Bremen-Verden's tax-levying department, almost entirely manned with Swedes and using Swedish as administrative language, was directly subordinated to the finance ministry in Stockholm.
From 1675 to 1676, troops from Brandenburg-Prussia, Lüneburg-Celle, Denmark-Norway, and the Prince-Bishopric of Münster captured Bremen-Verden in the course of a Reichsexekution during the Scanian War. The allied forces occupied Bremen-Verden, until they withdrew — under French influence — according to the Treaty of Saint-Germain-en-Laye of 1679 and the favourable Treaty of Celle. By the latter Baron, the Prince-Bishop of Münster, granted Sweden a loan amounting to 100,000 rixdollars, for which in return Swedish Bremen-Verden had to pawn its exclave of the town of Wildeshausen and the pertaining adjacence to the Prince-Bishopric of Münster. In the 1690s, the usual practise, that tax laws had a certain maturity, was abolished, so that the Swedish and Bremen-Verden's Estates had no chance any more to demand any concessions in return for a renewal of tax laws.
As in Sweden proper, the constitutional and administrative bodies in the Swedish dominions gradually lost de facto importance due to ever growing centralisation. Bremen-Verden's Estates lost more and more influence, they less and less often convened. After 1692, the estates' say had almost vanished. This led to considerable unease among the Estates, so that in May 1694 representatives of the General Government of Bremen-Verden and the Estates met at the former convent of Zeven to confer on the status of the Duchies.
In 1700, Bremen-Verden introduced — like all Protestant territories of imperial immediacy — the Improved Calendar, as it was called by Protestants, in order not to mention the name of Pope Gregory XIII. So Sunday, the 18 February of Old Style was followed by Monday, the 1 March New Style, while Sweden proper only followed suit in 1753.
In 1712, in the course of the Great Northern War against the Swedish supremacy in the Baltic, Denmark-Norway occupied plague stricken Bremen-Verden.

Personal union with Great Britain and Hanover (1715–1803)

In 1715, Frederick IV of Denmark, still fighting in the Great Northern War, gained a new ally in the anti-Swedish coalition, George I, King of Great Britain since 1714, and Elector of Hanover. In return for George I's aid, Denmark-Norway sold to him Bremen-Verden, which it kept under occupation since 1712. So the Prince-Electorate of Brunswick and Lunenburg, or colloquially called after its capital, the Electorate of Hanover; took de facto possession of Bremen-Verden and stipulated in the Treaty of Stockholm of 1719, settling the war with Sweden, to compensate the latter by 1 million rixdollars.. Elector George I Louis acquired Saxe-Lauenburg and Bremen-Verden.
In 1728, Emperor Charles VI enfeoffed George II Augustus, who in 1727 had succeeded his father George I Louis, with the reverted fief of Saxe-Lauenburg. By a redeployment of Hanoverian territories in 1731, Bremen-Verden was conveyed the administration of the neighboured Land of Hadeln at the Northern tip of Bremen-Verden, since 1180 an exclave, first of the younger Duchy of Saxony and from 1296 on of the Duchy of Saxe-Lauenburg. It took George II until 1733 to get the Emperor to also enfeoff him with the Duchies of Bremen and Verden.
At both feoffments George II of Great Britain swore that he would respect the existing privileges and constitutions of the Estates in Bremen-Verden and in Hadeln, thus confirming 400-year-old traditions of Estate participation in their governments. Being a Prince-Elector of the Holy Roman Empire and represented in its Diet by virtue of his Electorate of Hanover, George II Augustus didn't bother about Bremen-Verden's status of imperial estate.
Since Bremen-Verden had turned Hanoverian, it never again sent its own representatives to a Diet.
In 1730, Bremen-Verden's government was reorganised and retitled as Royal British and Electoral Brunswick-Lunenburgian Privy Council for Governing the Duchies of Bremen and Verden, which colloquially turned into the "Royal Government". Stade remained the capital. In Hanover, the electoral capital, the Privy Council of Hanover installed a new ministry in charge of the Imperial Estates ruled in personal union by the electors, it was called the Department of Bremen-Verden, Hadeln, Lauenburg and Bentheim.
In the course of the Anglo-French and Indian War in the North American colonies, Britain feared a French Invasion of Hanover. Thus George II formed an alliance with his cousin Frederick II of Brandenburg-Prussia, combining the North American conflict with the Austro–Brandenburg-Prussian Third Silesian or Seven Years' War.
In the summer of 1757, the French invaders defeated Prince William, Duke of Cumberland, son of George II and leading the Anglo-Hanoverian army. The French troops drove him and his army into remote Bremen-Verden, where in the former convent of Zeven he had to capitulate on September 18 with the Convention of Klosterzeven. But King George II denied his recognition of the convention. In the following year, the British army, supported by troops from Brandenburg-Prussia, Hesse-Kassel and the Principality of Brunswick and Lunenburg expelled again the occupants. Bremen-Verden remained unaffected for the rest of the war and after its end peace prevailed until the French Revolutionary Wars started.
The War of the First Coalition against France with Britain and the Hanover Electorate and other war allies forming the coalition, didn't affect Bremen-Verden's territory, since the French First Republic was fighting on several fronts, even on its own territory. But also in Bremen-Verden men were drafted in order to recruit the 16,000 Hanoverian soldiers fighting in the Low Countries under British command against Revolutionary France. In 1795, the Holy Roman Empire declared its neutrality, which of course included the British Electorate of Hanover, and a peace treaty with France was under negotiation until it failed in 1799.
By this time the War of the Second Coalition against France started and Napoléon Bonaparte urged Brandenburg-Prussia to occupy Hanover. In the Treaty of Basel of 1795 which Brandenburg-Prussia and France had stipulated, Brandenburg-Prussia would ensure the neutrality of the Holy Roman Empire in all the latter's territories north the demarcation line of the river Main, including Hanover. To this end also Hanover had to provide troops for the so-called demarcation army maintaining the armed neutrality. But in 1801, 24,000 Prussian soldiers invaded Hanover, which surrendered without a fight.
In April 1801, Brandenburg-Prussian troops arrived in Bremen-Verden's capital of Stade and stayed there until October of the same year. The United Kingdom of Great Britain and Ireland first ignored Brandenburg-Prussia's hostility, but when Brandenburg-Prussia joined the pro-French coalition of armed 'neutral' powers such as Denmark-Norway and the Russian Empire, Britain started to capture Brandenburg-Prussian sea vessels. After the Battle of Copenhagen in April 1801, the coalition fell apart and Brandenburg-Prussia withdrew its troops.

Napoleonic wars (1803–1813)

After Britain — without any ally — had declared war on France on May 18, 1803, French troops invaded the Electorate of Hanover on May 26 and installed — among others — two occupation companies in Bremen-Verden's capital Stade on June 18. According to the Convention of Artlenburg from July 5, 1803, confirming the military defeat of Hanover, the Hanoverian army was disarmed and its horses and ammunitions were handed over to the French. The Privy Council of Hanover, with minister Friedrich Franz Dieterich von Bremer holding up the Hanoverian stake, had fled to the trans-Elbian Hanoverian territory of Saxe-Lauenburg on May 30, 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 the French occupational troops left Hanover in a campaign against the Archduchy of Austria. 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, 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, including Bremen-Verden.
In 1807 France replaced the Privy Council and the Hanoverian estates of the realm, as announced on September 20, 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, however, allowing Bremen-Verden's government 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 March 1, 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 of January 1, 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 into the Hanoverian state. Since the Hanoverian monarchs had moved to London, Hanover had become a state of very conservative and backward rule, with a local government recruited from local aristocrats adding much to the preservation of outdated structures. The administrative union with Hanover only followed in 1823, when a local government reform united Bremen-Verden and Hadeln to form the High-Bailiwick of Stade, administered according to unitarian modern standards, thereby doing away with various traditional government forms of Bremen, Verden and Hadeln.
For the further history see Stade Region, which emerged by the establishment of the High-Bailiwick of Stade in 1823, comprising the territories of the former Duchies of Bremen and Verden and the Land of Hadeln.
