State of the Teutonic Order

The State of the Teutonic Order (Staat des Deutschen Ordens; Civitas Ordinis Theutonici); also Deutschordensstaat ( "German Order's State") or Ordensstaat ( "Order's State") was a crusader state formed by the Teutonic Knights or Teutonic Order during 13th century Northern Crusades along the Baltic Sea. The state was based in Prussia after the Order's conquest of the pagan Old Prussians which began in 1230, but also expanded to include the historic regions Courland, Gotland, Livonia, Neumark, Pomerelia and Samogitia. Its territory was in the modern countries of Estonia, Germany, Latvia, Lithuania, Poland, Russia and Sweden. Most of the territory was conquered by military orders, after which German colonization occurred to varying effect.

The Livonian Brothers of the Sword controlling Terra Mariana were incorporated into the Teutonic Order as its autonomous branch Livonian Order in 1237. In 1346, the Duchy of Estonia was sold by the King of Denmark for 19,000 Köln marks to the Teutonic Order. The shift of sovereignty from Denmark to the Teutonic Order took place on 1 November 1346.

Following its defeat in the Battle of Grunwald in 1410 the Teutonic Order fell into decline and its Livonian branch joined the Livonian Confederation established in 1422–1435. The Teutonic lands in Prussia were split in two after the Peace of Thorn in 1466. The western part of Teutonic Prussia was converted into Royal Prussia, which became a more integral part of Poland. The monastic state in the east was secularized in 1525 during the Protestant Reformation as the Duchy of Prussia, a Polish fief governed by the House of Hohenzollern. The Livonian branch continued as part of the Livonian Confederation until its dissolution in 1561.

Background
The Old Prussians withstood many attempts at conquest preceding the Teutonic Knights'. Bolesław I of Poland began the series of unsuccessful conquests when he sent Adalbert of Prague in 997. In 1147, Bolesław IV of Poland attacked Prussia with the aid of Kievan Rus, but was unable to conquer it. Numerous other attempts followed, and, under Duke Konrad I of Masovia, were intensified, with large battles and crusades in 1209, 1219, 1220 and 1222.

The West-Baltic Prussians successfully repelled most of the campaigns and managed to strike Konrad in retaliation. However the Prussians and Yotvingians in the south had their territory conquered. The land of the Yotvingians was situated in the area of what is today Podlachia. The Prussians attempted to oust Polish or Masovian forces from Yotvingia and Culmerland (or Chełmno Land), which by now was partially conquered, devastated and almost totally depopulated.

Konrad of Masovia had already called a crusade against the Old Prussians in 1208, but it was not successful. Konrad, acting on the advice of Christian, first bishop of Prussia, established the Order of Dobrzyń, a small group of 15 knights. The Order, however, was soon defeated and, in reaction, Konrad called on the Pope for yet another crusade and for help from the Teutonic Knights. As a result, several edicts called for crusades against the Old Prussians. The crusades, involving many of Europe's knights, lasted for sixty years.

In 1211, Andrew II of Hungary enfeoffed the Teutonic Knights with the Burzenland. In 1225, Andrew II expelled the Teutonic Knights from Transylvania, and they had to transfer to the Baltic Sea.

Early in 1224, Emperor Frederick II announced at Catania that Livonia, Prussia with Sambia, and a number of neighboring provinces were under Imperial immediacy (Reichsfreiheit). This decree subordinated the provinces directly to the Roman Catholic Church and the Holy Roman Emperor as opposed to being under the jurisdiction of local rulers.

At the end of 1224, Pope Honorius III announced to all Christendom his appointment of Bishop William of Modena as the Papal Legate for Livonia, Prussia, and other countries.

As a result of the Golden Bull of Rimini in 1226 and the Papal Bull of Rieti of 1234, Prussia came into the Teutonic Order's possession. The Knights began the Prussian Crusade in 1230. Under their governance, woodlands were cleared and marshlands made arable, upon which many cities and villages were founded, including Marienburg (Malbork) and Königsberg (Kaliningrad).

Unlike newly founded cities between the rivers Elbe and Oder the cities founded by the Teutonic Order had a much more re(ctan)gular sketch of streets, indicating their character as planned foundations. The cities were heavily fortified, accounting for the long lasting conflicts with the resistive native Old Prussians, with armed forces under command of the knights. Most cities were prevailingly populated with immigrants from Middle Germany and Silesia, where many knights of the order had their homelands.

The cities were usually given Magdeburg law town privileges, with the one exception of Elbing (Elbląg), which was founded with the support of Lübeckers and thus was awarded Lübeck law. While the Lübeckers provided the Order important logistic support with their ships, they were otherwise, with the exception of Elbing, rather uninvolved in the establishment of the Monastic State.

13th century
In 1234, the Teutonic Order assimilated the remaining members of the Order of Dobrzyń and, in 1237, the Order of the Livonian Brothers of the Sword. The assimilation of the Livonian Brothers of the Sword (established in Livonia in 1202) increased the Teutonic Order's lands with the addition of the territories known today as Latvia and Estonia.

In 1243, the Papal legate William of Modena divided Prussia into four bishoprics: Culm (Chełmno), Pomesania, Ermland (Warmia) and Samland (Sambia). The bishoprics became suffragans to the Archbishopric of Riga under the mother city of Visby on Gotland. Each diocese was fiscally and administratively divided into one third reserved for the maintenance of the capitular canons, and two thirds where the Order collected the dues. The cathedral capitular canons of Culm, Pomesania and Samland were simultaneously members of the Teutonic Order since the 1280s, ensuring a strong influence by the Order. Only Ermland's diocesan chapter maintained independence, enabling to establish its autonomous rule in the capitular third of Ermland's diocesan territory (Prince-Bishopric of Ermeland).

14th century
At the beginning of the 14th century, the Duchy of Pomerania, a neighboring region, plunged into war with Poland and the Margraviate of Brandenburg to the west.

In the Teutonic takeover of Danzig, the Teutonic Knights seized the city in November 1308. The Order had been called by King Władysław I of Poland. According to historical sources, many of the inhabitants of the city, Polish and German, were slaughtered. In September 1309, Margrave Waldemar of Brandenburg-Stendal sold his claim to the territory to the Teutonic Order for the sum of 10,000 Marks in the Treaty of Soldin. This marked the beginning of a series of conflicts between Poland and the Teutonic Knights as the Order continued incorporating territories into its domains.

While the Order promoted the Prussian cities by granting them extended surrounding territory and privileges, establishing courts, civil and commercial law, it allowed the cities less outward independence than free imperial cities enjoyed within the Holy Roman Empire.

So the members of the Hanseatic League did consider merchants from Prussian cities as their like, but also accepted the Grand Master of the Order as the sole territorial ruler ever at their Hanseatic Diets, representing Prussia. Thus Prussian merchants, along with those from Ditmarsh, were the only beneficiaries of a quasi membership within the Hanse, although lacking the background of citizenship in a fully autonomous or free city.

The Teutonic Order's possession of Danzig was disputed by the Polish kings Władysław I and Casimir the Great -- claims that led to a series of bloody wars and, eventually, lawsuits in the papal court in 1320 and 1333. A peace was concluded at Kalisz in 1343, where the Teutonic Order agreed that Poland should rule Pomerelia as a fief and Polish kings, therefore, retained the right to the title Duke of Pomerania.

In the conflict between the Hanse and Denmark on the trade in the Baltic King Valdemar IV of Denmark had held the Hanseatic city of Visby to ransom in 1361. However, the members of the Hanseatic league were undecided to unite against him. However, when Valdemar IV then captured Prussian merchant ships in the Øresund on their way to England, Grand Master Winrich of Kniprode travelled to Lübeck to propose a war alliance against Denmark, received with reluctance only by the important cities forming the Wendish-Saxon third of the Hanse.

Since Valdemar IV had also attacked ships of the Dutch city of Kampen and other destinations in the Zuiderzee, Prussia and Dutch cities, such as Kampen, Elburg and Harderwijk, allied themselves against Denmark. This then made the Hanse calling up a diet in Cologne in 1367, also convening the afore-mentioned and more non-member cities like Amsterdam and Brielle, founding the Cologne Federation as a war alliance, in order to ban the Danish threat. More cities from the Lower Rhine area till up to Livonia joined.

Of the major players only Bremen and Hamburg refused to send forces, but contributed financially. Besides Prussia, three more territorial partners, Henry II of Schauenburg and Holstein-Rendsburg, Albert II of Mecklenburg, and the latter's son Albert of Sweden, joined the alliance, attacking via land and sea, forcing Denmark to sign the Treaty of Stralsund in 1370. Several Danish castles and fortresses were then taken by Hanse forces for fifteen years, in order to secure the implementation of the peace conditions.

The invasions of the Teutonic Order from Livonia to Pleskau in 1367 had caused the Russians to recoup themselves on Hanse merchants in Novgorod, which again made the Order block exports of salt and herring into Russia. While the relations had eased by 1371 so that trade resumed, they soured again until 1388.

During the Lithuanian crusade of 1369/1370, ending with the Teutonic victory in the Battle of Rudau, Prussia enjoyed considerable support by English knights. So the Order welcomed English Merchant Adventurers, starting to cruise in the Baltic, competing with Dutch, Saxon and Wendish Hanseatic merchants, and allowed them to open outposts in its cities of Danzig and Elbing. However, this brought about a conflict with the rest of the Hanse, which was in a deep conflict with Richard II of England, who wanted to levy higher dues from the Hanse merchants, who only achieved an unsatisfactory compromise.

However, in May 1385 Richard II's navy suddenly attacked six Prussian ships – and those of more Hanse members – in the Zwin. Grand Master Conrad Zöllner von Rothenstein then immediately terminated all trade with England. When in the same year the Hanse evacuated all the Danish castles in fulfillment of the Treaty of Stralsund, Prussia argued in favour of a renewal of the Cologne Federation for the upcoming conflict with England, but could not prevail.

The cities preferred to negotiate and take retaliatory actions, such as counter-confiscation of English merchandise. So when in 1388 Richard II finally reconfirmed the Hanseatic trade privileges, Prussia reallowed the merchant adventurers granting them staying permissions, however, renounced again by Grand Master Conrad of Jungingen in 1398.

In the conflict with the Burgundian Philip the Bold on the Hanse privileges in the Flemish cities the positions of the Hanse cities and Prussia were again reversed. Here the majority of the Hanse members decided in a Hanseatic diet on 1 May 1388 for an embargo against the Flemish cities, while Prussia could not prevail with its plea for further negotiations.

So the Order's Großschäffer from Königsberg, holding the monopoly in amber export, achieved the exceptional permission to continue amber exports to Flanders and textile imports in return. On the occasion of the ban on Flemish trade, the Hanse urged Prussia and Livonia again to interrupt the exchange with Novgorod too, anyway with both blockades Russian and Flemish commodities could not reach their final destinations. In 1392 it was then Grand Master Conrad of Wallenrode who supported the Flemings to achieve an acceptable agreement with the Hanse resuming the bilateral trade. While a Hanseatic delegation under Johann Niebur reopened trade with Novgorod in the same year, after reconfirmation of the previous mutual privileges.

Since the late 1380s grave piracy by privateers, promoted by Albert of Sweden and Mecklenburg actually directed against Margaret I of Denmark, blocked seafaring to the herring supplies at the Scania Market, thus fish prices tripled in Prussia. The Saxon Hanse cities urged Prussia to intervene, but Conrad of Jungingen was more worried about a Danish victory. So only after the cities, led by Lübeck's burgomaster Hinrich Westhof, had liaised the Treaty of Skanör (1395), Albert's defeat manifested, so that Prussia finally sent out its ships, led by Danzig's city councillor Conrad Letzkau. Until 1400 the united Teutonic-Hanseatic flotilla then thoroughly cleared the Baltic Sea from pirates, the Victual Brothers, and even took the island of Gotland in 1398.

15th century
In 1402, the March of Brandenburg gave the New March in pawn to the Teutonic Order, which kept it until Brandenburg redeemed it again in 1454 and 1455, respectively, by the Treaties of Cölln and Mewe.

In 1408 Letzkau served as a diplomat to Queen Margaret I and arranged that the Order sold Gotland to Denmark. In 1410, with the death of Rupert, King of the Germans, war broke out between the Teutonic Knights, supported by Pomerania, and a Polish-Lithuanian alliance supported by Ruthenian and Tatar auxiliary forces. Poland and Lithuania triumphed following a victory at the Battle of Grunwald (Tannenberg).

The Order assigned Heinrich von Plauen to defend Prussian Pomerania (Pomerelia), who moved rapidly to bolster the defence of Marienburg Castle in Prussian Pomesania. Heinrich von Plauen was elected vice-grand master and led the Teutonic Knights through the Siege of Marienburg in 1410. Eventually von Plauen was promoted to Grand Master and, in 1411, concluded the First Treaty of Thorn with King Władysław II Jagiełło of Poland.

In March 1440, gentry (mainly from Culmerland) and the Hanseatic cities of Danzig, Elbing, Kneiphof, Thorn and other Prussian cities founded the Prussian Confederation to free themselves from the overlordship of the Teutonic Knights. Due to the heavy losses and costs after the war against Poland and Lithuania, the Teutonic Order collected taxes at steep rates. Furthermore, the cities were not allowed due representation by the Teutonic Order.

In February 1454, the Prussian Confederation asked King Casimir IV of Poland to support their revolt and to become head of Prussia in personal union. King Casimir IV agreed and the War of the Cities or Thirteen Years' War broke out. The Second Peace of Thorn in October 1466 ended the war and provided for the Teutonic Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia and the remaining part of the Order's land became a fief of Poland.

16th century and aftermath
During the Protestant Reformation, endemic religious upheavals and wars occurred across the region. In 1525, during the aftermath of the Polish-Teutonic War (1519–1521), Sigismund I the Old, King of Poland, and his nephew, the last Grand Master of the Teutonic Knights, Albert of Brandenburg-Ansbach, a member of a cadet branch of the House of Hohenzollern, agreed that the latter would resign his position, adopt Lutheran faith and assume the title of Duke of Prussia. Thereafter referred to as Ducal Prussia (Herzogliches Preußen, Preußen Herzoglichen Anteils; Prusy Książęce), remaining a Polish fief.

Thus in a deal partially brokered by Martin Luther, Roman Catholic Teutonic Prussia was transformed into the Duchy of Prussia, the first Protestant state. Sigismund's consent was bound to Albert's submission to Poland, which became known as the Prussian Homage. On 10 December 1525 at their session in Königsberg the Prussian estates established the Lutheran Church in Ducal Prussia by deciding the Church Order.

The Habsburg-led Holy Roman Empire continued to hold its claim to Prussia and furnished grand masters of the Teutonic Order, who were merely titular administrators of Prussia, but managed to retain many of the Teutonic holdings elsewhere outside of Prussia. Joachim II Hector, Elector of Brandenburg, who had converted to Lutheranism in 1539, was after the co-enfeoffment of his line of the Hohenzollern with the Prussian dukedom. So he tried for gaining his brother-in-law Sigismund II Augustus of Poland and finally succeeded, including the then usual expenses. On 19 July 1569, when Albert Frederick rendered King Sigismund II homage and was in return enfeoffed as Duke of Prussia in Lublin, the King simultaneously enfeoffed Joachim II and his descendants as co-heirs.

In 1618, the Prussian Hohenzollern were extinct in the male line, and so the Polish fief of Prussia was passed on to the senior Brandenburg Hohenzollern line, the ruling margraves and prince-electors of Brandenburg, who thereafter ruled Brandenburg (a fief of the Holy Roman Empire), and Ducal Prussia (a Polish fief), in personal union. This legal contradiction made a cross-border real union impossible; however, in practice, Brandenburg and Ducal Prussia were more and more ruled as one, and colloquially referred to as Brandenburg-Prussia.

Frederick William, Duke of Prussia and Prince-elector of Brandenburg, sought to acquire Royal Prussia in order to territorially connect his two existing fiefs. An opportunity occurred when Charles X Gustav of Sweden, in his attempt to conquer Poland (cf. Swedish Deluge), promised to cede to Frederick William the Polish Prussian voivodeships of Chełmno, Malbork and Pomerania (Pomerelia) as well as the Prince-Bishopric of Ermeland, if Frederick William supported the Swedish campaign. This offer was speculative, since Frederick William would have to commit to military support of the campaign, while the reward was conditional on achieving victory.

John II Casimir of Poland forestalled the Swedish-Prussian alliance by submitting a counter-offer, which Frederick William accepted. On July 29, 1657 they signed the Treaty of Wehlau in Wehlau (Welawa; today Znamensk). In return for Frederick William's renunciation of the Swedish-Prussian alliance, John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia (Herzogtum Preußen). Thus after almost 200 years of Polish suzerainty, Prussia regained full sovereignty in 1657, a necessary prerequisite for elevating Ducal Prussia to become the sovereign Kingdom of Prussia in 1701 (not to be confused with Polish Royal Prussia).

The nature of the de facto collectively ruled governance of Brandenburg-Prussia became more apparent through the titles of the higher ranks of the Prussian government, seated in Brandenburg's capital of Berlin after the return of the court from Königsberg, where they had sought refuge from the Thirty Years' War (1618–1648). However, the legal amalgamation of the Kingdom of Prussia (a sovereign state) with Brandenburg (a fief of the Holy Roman Empire) was achieved only after the dissolution of the Empire in 1806 during the Napoleonic Wars.
