, a Teutonic castle in present-day
Poland, in the palace museum The history of Mergentheim Palace begins in the 12th century, when the Counts of built a castle on the east side of a village called Mergintaim. This castle was then obtained by the
House of Hohenlohe, who began expanding it in 1169. In 1219 the master of the castle, Andreas von Hohenlohe, joined the Teutonic Knights with two relatives and donated Mergentheim to the Order. This transfer to the was presided over by ,
Bishop of Würzburg, and confirmed by
Frederick II, Holy Roman Emperor. The Teutonic Knights were given extensive rights in and over Mergentheim, including the
limiting of the citizenry's ability to make legal appeals to the local courts, by
Louis IV, Holy Roman Emperor in 1340. By the 15th century, the Teutonic outpost at Mergentheim had 19 knights, four of whom were ordained priests. On 26 March 1524, the citizens of Mergentheim, participating in the
German Peasants' War, rose in revolt to the Teutonic Order and sacked one of their properties in the town. The gates to the town were opened to the peasants of the Tauber valley on 6 April, whereupon more looting took place and the castle was occupied. The residence of the German Master,
Horneck Castle, was also attacked by Swabian peasants in 1525 and destroyed. Meanwhile, the
Teutonic state in Prussia was
secularized by the
Kingdom of Poland. In response to the loss of Horneck Castle, the Franconian bailiwick offered Mergentheim as a residence to the German Master,
Walter von Cronberg, in 1527. Cronberg accepted and that year combined the offices of the German Master and Grand Master of the Teutonic Order, making Mergentheim the headquarters of the entire Order. This arrangement was provisional until the loss of Prussia became inexorable with the destruction of the
Livonian Order in 1561, obliging the Grand Master to remain in Mergentheim. 17 Grand Masters would govern the Order and its territories from Mergentheim until the Order was expelled from the town in 1809.
Headquarters of the Teutonic Order and the palace as it appeared in 1750 In 1568,
Georg Hund von Wenkheim, Grand Master since 1566, began to expand Mergentheim Castle into a palatial residence.
Maximilian III, Archduke of Austria, as Grand Master of the Teutonic Order, established a
seminary on the grounds of Mergentheim Palace in 1606–07. It was to be staffed by 12 knights gathered from the Teutonic bailiwicks. In 1694,
Francis Louis of Palatinate-Neuburg, the
Prince-Bishop of Breslau, was elected Grand Master of the Teutonic Order to replace his late brother
Louis Anton. Francis Louis, who go on to hold five high ecclesiastical offices and extensively reform the Order, rarely spent time at Mergentheim. Towards the end of his tenure, however, he wrote to the Mergentheim authorities about constructing a new high altar in the palace church. When he was informed that it had fallen into disrepair, he ordered a new church. Construction began in 1730, but Francis Louis died in 1732. He was succeeded as Grand Master by
Clemens August of Bavaria, who finished the church in 1736.
Secularization According to the 1797
Peace of Campo Formio, which concluded the
War of the First Coalition, France was to annex the
Left Bank of the Rhine and the German princes who lost territory to France were to be compensated with ecclesiastical possessions east of the Rhine. This compensation ballooned into the
Reichsdeputationshauptschluss of 1802–03, which erased all ecclesiastical states except the
Electorate of Mainz, which was
moved south to Regensburg, and the Teutonic Knights at Mergentheim, and the
Knights Hospitaller at
Heitersheim. The ecclesiastical states were to be governed by German nobles, with the Teutonic Knights coming under Austrian control. Just two years later in 1805, at the end of the
War of the Third Coalition, the
Peace of Pressburg gave Mergentheim fully to Austria. Austrian troops were stationed in the town until 1809, when it was occupied by the
Kingdom of Württemberg on 20 April 1809, during the
War of the Fifth Coalition. In the process of
German mediatization that followed in 1809,
Napoleon Bonaparte stripped the Teutonic order of its possessions in what was to become the
Confederation of the Rhine. Mergentheim was awarded to Württemberg on 29 May 1809 In the process of annexation, Württemberger authorities looted Mergentheim Palace and moved the seminary's library to
Stuttgart, the kingdom's capital. In 1827,
Duke Paul Wilhelm of Württemberg received Mergentheim Palace as his residence following his marriage to
Princess Maria Sophia of Thurn and Taxis. Paul Wilhelm, a natural scientist and explorer, displayed ethnological, zoological, and botanical specimens and curios collected in his travels in twenty of the palace's rooms. Baron Carl Joseph von Adelsheim managed the Duke's collection, and his own collection of antiquities would later form the basis of the Mergentheim Palace Museum.
