The Duchy of Prussia (German: Herzogtum Preußen, Polish: Księstwo Pruskie) or Ducal Prussia (German: Herzogliches Preußen, Polish: Prusy Książęce) was a duchy in eastern Prussia established during the Protestant Reformation in 1525. It was the first Lutheran duchy with a dominant German-speaking population, as well as Polish and Lithuanian minorities. In old texts and in Latin, the term Prut(h)enia refers alike to Ducal Prussia, its western neighbor Royal Prussia, and their common predecessor, Teutonic Prussia. The adjectival form of the name was "Prut(h)enic".

In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert, secularized the order's Prussian territory, becoming Albert, Duke of Prussia. His duchy, which had its capital in Königsberg (Polish: Królewiec, Lithuanian: Karaliaučius; modern Kaliningrad), was established as fief of the Crown of Poland. It was inherited by the Hohenzollern prince-electors of Brandenburg in 1618; this personal union is referred to as Brandenburg-Prussia. Frederick William, the "Great Elector" of Brandenburg, achieved full sovereignty over the territory in the 1657 Treaty of Wehlau, which was confirmed in the 1660 Treaty of Oliva. The Duchy of Prussia was elevated to the Kingdom of Prussia in 1701.

As Protestantism spread among the laity of the Teutonic Monastic State of Prussia, dissent began to develop against the Roman Catholic rule of the Teutonic Knights, whose Grand Master, Albert of Brandenburg-Ansbach, a member of a cadet branch of the House of Hohenzollern, lacked the military resources to assert the order's authority.

After of Pomesania and of Samland, who had converted to Lutheranism in 1523,[1] and a number of his commanders already supporting Protestant ideas, Albert began to consider a radical solution.

At Wittenberg in 1522 and at Nuremberg in 1524, Martin Luther encouraged him to convert the order's territory into a secular principality under his personal rule, as the anachronistic Teutonic Knights would not be able to survive the Protestant Reformation.[2]

On April 10, 1525 Albert resigned his position, became a Protestant, and in the Prussian Homage was granted the title "Duke of Prussia" by his new feudal overlord, King Sigismund I the Old of Poland, who was also his uncle. In a deal partially brokered by Luther, Ducal Prussia became the first Protestant state, anticipating the dispensations of the Peace of Augsburg of 1555. The "S" on the duchy's coat of arms represented Albert's sovereign, Sigismund. Charles V, Holy Roman Emperor, and Pope Clement VII objected to the Prussian Homage, which was derided as the Krakauer Kuhhandel ("Cracow horse-trading").

When Albert returned to Königsberg, he publicly declared his conversion and announced to a quorum of Teutonic Knights his new ducal status. The knights who disapproved of the decision were pressured into acceptance by Albert's supporters and the burghers of Königsberg, and only Eric of Brunswick-Wolfenbüttel, Komtur of Memel, opposed the new duke. On 10 December 1525, at their session in Königsberg, the Prussian estates established the Lutheran Church in Ducal Prussia by deciding the Church Order.[1]

By the end of Albert's rule, the offices of Großkomtur and Ordensmarschall had deliberately been left vacant and the order had only 55 knights in Prussia. Some of the knights converted to Lutheranism in order to retain their property and then married into the Prussian nobility, while others returned to the Holy Roman Empire and remained Catholic.[3] These remaining Teutonic Knights, led by the next Grand Master, Walter von Cronberg, continued to unsuccessfully claim Prussia, but retained much of the estates in the Teutonic bailiwicks outside of Prussia.

On 1 March 1526 Albert married Franconia and Upper Silesia. Albert also found himself reliant on support from his Jagiellonian uncle Sigismund I of Catholic Poland, as the Holy Roman Empire and the Roman Catholic Church had banned him for his Protestantism.

Ducal Prussia's full sovereignty allowed Elector Province of East Prussia, while most of former Royal Prussia became the Province of West Prussia. The Kingdom of Prussia, then consisting of East and West Prussia, being a sovereign state, and Brandenburg, being a fief within the Holy Roman Empire, were amalgamated de jure only after the latter's dissolution in 1806.

Kingdom in 1701

King John II Casimir of Poland didn't take the Swedish-Prussian alliance lying down. He submitted a counter-offer and Frederick William accepted. On July 29, 1657 they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now 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.[10] After almost 200 years of Polish suzerainty over the Teutonic Monastic State of Prussia and its successor Ducal Prussia, full sovereignty was regained. Therefore Duchy of Prussia then became the more adequate appellation for the state. Full sovereignty was a necessary prerequisite for upgrading Ducal Prussia to become the sovereign Kingdom of Prussia, not to be confused with Polish Royal Prussia, in 1701.

Frederick William the Great Elector, duke of Prussia and prince-elector of Brandenburg, was after acquiring Royal Prussia in order to territorially connect his two fiefs. Yet, during the Second Northern War, Charles X Gustav of Sweden invaded Ducal Prussia and dictated the Treaty of Königsberg (January 1656), which made the duchy a Swedish fief. In the subsequent Treaty of Marienburg (June 1656), Charles X Gustav promised to cede to Frederick William the voivodships of Chełmno, Malbork, Pomerellia, and the Prince-Bishopric of Ermland, if Frederick William would support Charles Gustav's effort.[10] The deal was a mere spec, since Frederick William would definitely have to provide military support, while the reward was only under the condition of a victory. When the tide of the war turned against Charles X Gustav, he concluded the Treaty of Labiau (November 1656), making Frederick William I the full souvereign in Ducal Prussia and Ermland.

Brandenburg, being a fief of the Holy Roman Empire, and Ducal Prussia, being a Polish fief, made a cross-border real union legally impossible. De facto Brandenburg and Ducal Prussia were more and more ruled as one, and colloquially referred to as Brandenburg-Prussia.

In 1618, the Sigismund III Vasa, thus the personal union Brandenburg-Prussia was confirmed.[5] Many of the Prussian Junkers were opposed to rule by the House of Hohenzollern of Berlin and appealed to Sigismund III Vasa for redress, or even incorporation of Ducal Prussia into the Polish kingdom, although without success.[9]

As in 1618, Albert Frederick had no surviving male heirs, the co-enfeoffment of 1569, confirmed by the Treaty of Warsaw in 1611, allowed his son-in-law, Elector John Sigismund of the Hohenzollern branch in Brandenburg, to become the duke's legal successor, thereafter ruling Brandenburg and Ducal Prussia in personal union.

Transition into Brandenburg-Prussia in 1618

Following King Sigismund III's Prussian regency contract (1605) with Joachim Frederick of Brandenburg and his Treaty of Warsaw, 1611, with John Sigismund of Brandenburg, confirming the Brandenburgian co-enfeoffment, these two regents guaranteed free practice of Catholic religion in prevailingly Lutheran Prussia. Based on these contracts some Lutheran churches were reconsecrated as Catholic places of worship (e.g. Nicholas Church, Elbing in 1612).

On 19 July 1569, when Brandenburg-Ansbach to become Regent of Prussia in 1577.

When Albert died in 1568, his teenage son (exact age is unknown) Albert Frederick inherited the duchy. Joachim II Hector, Elector of Brandenburg, who had converted to Lutheranism in 1539, was after the co-enfeoffment (Mitbelehnung) 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.

Lack of heirs

Administratively, little changed in the transition from the Teutonic Knights to ducal rule. Although he was formally a vassal of the crown of Poland, Albert retained self-government for Prussia, his own army, the minting of his currency, a provincial assembly (Prussian Diet, Landtag), and had substantial autonomy in foreign affairs.[8]

While the composition of the nobility changed little in the transition from monastic state to duchy, the hold of the nobility over the dependent peasantry increased. Prussia's free peasants, called Kölmer (holders of free estates according to Culm law), held with about a sixth of the arable land a considerable share as compared with other nations in the feudal era.[7] The peasant rebellion had frightened the nobles, however, causing them to look to Duke Albert for leadership.

In 1544 Duke Albert founded the Albertina University in Königsberg, which became the principal educational establishment for Lutheran pastors and theologians of Prussia.[1] The usage of the native languages in service made him appoint exiled Protestant Lithuanian pastors as professors (e.g. Stanislovas Rapolionis and Abraomas Kulvietis), making the Albertina also a centre of Lithuanian language and literature.[6]

They claimed to be rebelling against the harsh nobility, not against Duke Albert, who was away in the Holy Roman Empire, but they would only swear allegiance to him in person. Upon Albert's return from the Empire, he called for a meeting of the peasants in a field, whereupon he surrounded them with loyal troops and had them arrested without incident; the leaders of the rebellion were subsequently executed.[4] Although there were no more large-scale rebellions, Ducal Prussia became known as a land of Protestant dissent and sectarianism.[5]

A peasant rebellion broke out in Sambia (German: Samland) in 1525. The combination of taxation by the nobility, the furor of the Protestant Reformation, and the abrupt secularization of the Teutonic Order's remaining Prussian lands exacerbated peasant unrest. The relatively well-to-do rebel leaders, including a miller from Kaimen and an innkeeper from Schaaken in Prussia, were supported by sympathizers in Königsberg. The rebels demanded the elimination of newer taxes by the nobility and a return to an older tax of two marks for every Hufe (the Prussian hide measuring approximately forty acres).

The Church Order of 1525 provided for visitations of the parishioners and pastors, first carried out by Bishop George in 1538.[1] Because Ducal Prussia was ostensibly a Lutheran land, authorities travelled throughout the duchy ensuring that Lutheran teachings were being followed and imposing penalties on pagans and dissidents. The rural population of native descent was only thoroughly Christianised starting with the Reformation in Prussia.[1]

Already on 18 January 1524 Bishop George had ordered to only use native languages at baptisms, which improved the access towards the people.[1] There was little active resistance to the new creed, although the fact that the Teutonic Knights had brought Catholicism and Protestantism made the transition easier.[5]
