Hochmeister Albert
         of Prussia 
 
Albert of Prussia (German: Albrecht
         von Preussen, 17 May 1490 – 20 March 1568)
         was the 37th Grand Master of the Teutonic Knights, who after converting to Lutheranism, became the first ruler of the Duchy
         of Prussia, the secularized state that emerged from the former Monastic State of the Teutonic Knights. Albert was the first
         European ruler to establish Lutheranism, and thus Protestantism, as the official state religion  of his lands. He proved instrumental
         in the political spread of  Protestantism in its early stage, ruling the Prussian lands for nearly  six decades (1510–1568). A member of the Brandenburg-Ansbach branch of the
         House of Hohenzollern,  Albert became Grand Master, where his skill in political administration  and leadership
         ultimately succeeded in reversing the decline of the  Teutonic Order. But Albert, who was sympathetic to the demands of Martin Luther, rebelled against the Catholic
         Church and the Holy Roman Empire  by
         converting the Teutonic state into a Protestant and hereditary  realm, the Duchy of Prussia, for which he paid homage to his
         uncle, the King of Poland, Sigismund I. That arrangement was confirmed by the Treaty of Kraków in 1525. Albert pledged a personal oath to the King and in return was invested with the duchy for himself and his
         heirs.
 
 
 Albert's rule in Prussia was fairly prosperous.
         Although he had some  trouble with the peasantry, the confiscation of the lands and treasures  of the Catholic Church enabled
         him to propitiate the nobles and provide  for the expenses of the newly established Prussian court. He was active  in imperial
         politics, joining the League of Torgau in 1526, and acted in unison with the Protestants in plotting to overthrow Emperor
         Charles V after the issue of the Augsburg Interim in May 1548. Albert established schools in every town and founded Königsberg
         University in 1544. He promoted culture and arts, patronising the works of Erasmus Reinhold and Caspar Hennenberger.
          During the final years of his rule, Albert was forced to raise taxes  instead of further confiscating now-depleted church
         lands, causing  peasant rebellion. The intrigues of the court favourites Johann Funck and Paul Skalić also led to various
         religious and political disputes. Albert spent his final years virtually deprived of power and died at Tapiau on 20 March
         1568. His son, Albert Frederick, succeeded him as Duke of Prussia. Albert's dissolution of the Teutonic State caused the founding of the  Duchy of Prussia, paving the way
         for the rise of the House of  Hohenzollern. He is therefore often seen as the father of the Prussian  nation, and even as
         indirectly responsible for the unification of Germany. Duke Frederick of Saxony, Grand Master of the Teutonic Order,  died in December 1510. Albert
         was chosen as his successor early in 1511  in the hope that his relationship to his maternal uncle, Sigismund I the Old, Grand
         Duke of Lithuania and King of Poland, would facilitate a settlement of the disputes over eastern Prussia, which had been held
         by the order under Polish suzerainty since the Second Peace of Thorn (1466). The new Grand Master, aware of his
         duties to the empire and to the  papacy, refused to submit to the crown of Poland. As war over the  order's existence appeared
         inevitable, Albert made strenuous efforts to  secure allies and carried on protracted negotiations with Emperor  Maximilian
         I. The ill-feeling, influenced by the ravages of members of  the Order in Poland, culminated in a war which began
         in December 1519 and devastated Prussia. Albert was granted a four-year truce early in 1521.
 
 
 The dispute was referred to Emperor Charles
         V  and other princes, but as no settlement was reached Albert continued  his efforts to obtain help in view of a renewal of
         the war. For this  purpose he visited the Diet of Nuremberg in 1522, where he made the acquaintance of the Reformer Andreas
         Osiander, by whose influence Albert was won over to Protestantism. The Grand Master then journeyed to Wittenberg, where he was advised by Martin Luther  to abandon
         the rules of his order, to marry, and to convert Prussia  into a hereditary duchy for himself. This proposal, which was  understandably
         appealing to Albert, had already been discussed by some  of his relatives; but it was necessary to proceed cautiously, and
         he  assured Pope Adrian VI that he was anxious to reform the order and punish the knights who had adopted Lutheran  doctrines. Luther for his part did not stop at the suggestion, but in  order to facilitate the change made special
         efforts to spread his  teaching among the Prussians, while Albert's brother, Margrave George of Brandenburg-Ansbach,
         laid the scheme before their uncle, Sigismund I the
         Old of Poland.
 
 
Duke
         in Prussia
         After some delay Sigismund assented to the offer, with
         the provision  that Prussia should be treated as a Polish fiefdom; and after this  arrangement had been confirmed by a treaty
         concluded at Kraków, Albert pledged a personal oath to Sigismund I and was invested with the duchy for himself and
         his heirs on 10 February 1525. The Estates of the land then met at Königsberg  and took the oath of allegiance to the new duke, who used his
         full  powers to promote the doctrines of Luther. This transition did not,  however, take place without protest. Summoned before
         the imperial court  of justice, Albert refused to appear and was proscribed, while the order  elected a new Grand Master,
         Walter von Cronberg, who received Prussia as a fief at the imperial Diet of Augsburg. As the
         German princes were experiencing the tumult of the Reformation, the German Peasants' War, and the wars against the Ottoman Turks, they did not enforce the ban on the duke, and agitation against him soon died away. In imperial politics Albert was fairly active. Joining the League of Torgau  in 1526, he acted in unison with the Protestants, and was among the  princes who banded and plotted together
         to overthrow Charles V after the  issue of the Augsburg
         Interim  in May 1548. For various reasons, however,
         poverty and personal  inclination among others, he did not take a prominent part in the  military operations of this period.
 
 
 The early years of Albert's rule in Prussia were fairly prosperous.  Although he had some
         trouble with the peasantry, the lands and treasures  of the church enabled him to propitiate the nobles and for a time to
          provide for the expenses of the court. He did something for the  furtherance of learning by establishing schools in every
         town and by  freeing serfs who adopted a scholastic life. In 1544, in spite of some  opposition, he founded Königsberg
         University, where he appointed his friend Andreas Osiander to a professorship in 1549. Albert also paid for the printing of
         the Astronomical "Prutenic Tables" compiled by Erasmus Reinhold and the first maps of Prussia by Caspar Hennenberger. Osiander's appointment was the beginning of the troubles which 
         clouded the closing years of Albert's reign. Osiander's divergence from  Luther's doctrine of justification
         by faith involved him in a violent quarrel with Philip
         Melanchthon,  who had adherents in Königsberg,
         and these theological disputes soon  created an uproar in the town. The duke strenuously supported Osiander,  and the area
         of the quarrel soon broadened. There were no longer church  lands available with which to conciliate the nobles, the burden
         of  taxation was heavy, and Albert's rule became unpopular.

 After Osiander's death in 1552, Albert favoured
         a preacher named Johann Funck, who, with an adventurer named Paul Skalić,  exercised great influence over him and obtained
         considerable wealth at  public expense. The state of turmoil caused by these religious and  political disputes was increased
         by the possibility of Albert's early  death and the need, should that happen, to appoint a regent, as his only son, Albert
         Frederick  was still a mere youth. The duke was forced to consent to a  condemnation of the teaching of Osiander, and the
         climax came in 1566  when the Estates appealed to King Sigismund II Augustus  of Poland, Albert's cousin, who sent a commission
         to Königsberg. Skalić  saved his life by flight, but Funck was executed. The question of the  regency was settled,
         and a form of Lutheranism was adopted and declared  binding on all teachers and preachers. Virtually deprived of power, the duke lived
         for two more years, and died at Tapiau on 20 March 1568 of the plague, along with his wife. Cornelis Floris de Vriendt
         designed his tomb within Königsberg Cathedral. Albert
         was a voluminous letter writer, and corresponded with many of the leading personages of the time.
 
 
Legacy
 Although Albert has received relatively little recognition in German history, his dissolution of the Teutonic State
         caused the founding of the Duchy  of Prussia, which would eventually become arguably the most powerful  German state and instrumental
         in uniting the whole of Germany. Albert is  therefore often seen as the father of the Prussian nation, and even as  indirectly
         responsible for the unification of Germany. He was a skilled political administrator and leader,
         and effectively  reversed the decline of the Teutonic Order, until he betrayed it by  transforming the order's lands into
         his own duchy, secularizing it in  the process. Albert was the first German noble to support Luther's ideas and in 1544 founded the University of Königsberg, the Albertina, as a rival to the Roman Catholic Cracow
         Academy. It was the second Lutheran university in the
         German states, after the University of Marburg.

 A relief of Albert over the Renaissance-era portal
         of Königsberg Castle's southern wing was created by Andreas Hess in 1551 according to plans by Christoph Römer. Another
         relief by an unknown artist was included in the wall of the  Albertina's original campus. This depiction, which showed the
         duke with  his sword over his shoulder, was the popular "Albertus", the symbol of  the university. The original
         was moved to Königsberg Public Library to protect it from the elements, while the sculptor Paul Kimritz created a duplicate
         for the wall. Another version of the "Albertus" by Lothar Sauer was included at the entrance of the Königsberg
         State and Royal Library. In 1880 Friedrich Reusch created a sandstone
         bust of Albert at the Regierungsgebäude, the administrative building for Regierungsbezirk Königsberg. On 19 May
         1891 Reusch premiered a famous statue of Albert at Königsberg Castle with the inscription: "Albert of Brandenburg,
         Last Grand Master, First Duke in Prussia". Albert Wolff also designed an equestrian statue of Albert located at
         the new campus of the Albertina. King's Gate contains a statue of Albert. Albert was oft-honored in the quarter Maraunenhof  in northern Königsberg. Its main street was named Herzog-Albrecht-Allee
          in 1906. Its town square, König-Ottokar-Platz, was renamed  Herzog-Albrecht-Platz in 1934 to match its church, the Herzog-Albrecht-Gedächtniskirche.
