plow their fields. A short time later, Imperial troops reached the city and forced the Württemberg troops to withdraw; however, weakened by the long war they could not enforce the peace. The Plague broke out in 1635, which decimated the already weakened population. That year the castle fell into the hands of Maximilian I, Elector of Bavaria (1573–1651), who held it until 1637, when Hohenzollern rule was restored. The troops of Bernard of Saxe-Weimar, who was allied with the French, plundered the city completely in 1638 in 12 days. The residents were reduced to eating nettles and snails, having already eaten the cats and dogs. In 1639, the city was again occupied by the Bavarians until 1650. Although the Peace of Westphalia was signed in 1648, the troops remained two years longer because the outstanding taxes had not been paid. Enlightenment The architecture of the city was greatly influenced by the architect Pierre Michel d'Ixnard, who was a predecessor of Classicism in southern Germany. Nineteenth century The princes of Hohenzollern maintained good relations with Napoleon, and the last reigning prince, Constantine, Prince of Hohenzollern-Hechingen married Eugénie de Beauharnais. The first large palace in the city was Friedrichsburg. The construction of a new palace—Neues Schloss—to replace it was started in 1818, but it was never properly finished because of the financial constraints of Prince Frederik. Neues Schloss is currently the headquarters of the Zollernalb Savings Bank. Starting in 1826, Constantine and Eugénie made Hechingen into a cultural center in southern Germany. They had famous guests, including Eugénie's cousin, the future Napoleon III, Hector Berlioz, and Franz Liszt. After the Revolution of 1848, Constantine retired from public life, and his county passed into the control of the Protestant kingdom of Prussia in 1850. Hohenzollern-Hechingen was then incorporated into the district of Sigmaringen, which became the capital. In that same year, Friedrich August Stüler began the restoration of the castle. By 1850, Hechingen had started to industrialize, primarily with Jewish enterprises. By 1871 the city had become one of the most important economic centres in the region, with textiles and machine shops among the major industries. Twentieth century In 1925, Hechingen became the capital of a new Landkreis. Much of the architecture of the city was destroyed or damaged during World War II by Nazi attempts to build air raid shelters in public buildings. The town hall was so damaged that it had
