Karl Anselm, 4th Prince of Thurn and Taxis, full German name: Karl Anselm Fürst von Thurn und Taxis (2 June 1733 - 13 November 1805) was the fourth Prince of Thurn and Taxis, Postmaster General of the Imperial Reichspost, and Head of the Princely House of Thurn and Taxis from 17 March 1773 until his death on 13 November 1805. Karl Anselm served as Prinzipalkommissar at the Perpetual Imperial Diet in Regensburg for Joseph II, Holy Roman Emperor and Francis II, Holy Roman Emperor from 1773 to 1797.
Karl Anselm was the eldest son of Alexander Ferdinand, 3rd Prince of Thurn and Taxis and his first wife Margravine Sophie Christine of Brandenburg-Bayreuth.
Karl Anselm married Duchess Auguste of Württemberg, sixth and youngest child of Karl Alexander, Duke of Württemberg and his wife Princess Maria Augusta of Thurn and Taxis, on 3 September 1753 in Stuttgart, Duchy of Württemberg. Karl Anselm and Auguste had eight children:
Auguste bore Karl Anselm eight children until 1772. After several assassination attempts by his wife, Karl Anselm banished Auguste in January 1776 to strict house arrest at first to Burg Trugenhofen (later renamed Schloss Taxis) in Dischingen and then to Schloss Hornberg in the Black Forest, where she died on 4 June 1787. The couple legally divorced in 1776. Following the death of his first wife, Karl Anselm married that same year morganatically to Elisabeth Hildebrand.
Karl Anselm acquired in 1786, the Swabian county of Friedberg-Scheer and had to spend almost the entire proceeds from the Imperial Reichspost. Thereupon the Emperor Joseph II brought the county to "Gefürsteten Grafschaft" status. During the invasion of French troops in the Austrian Netherlands in 1794, the local properties of the Thurn und Taxis family were seized. With the further advance of the French troops, all the possessions of the Thurn and Taxis were lost. To compensate, Karl Anselm was awarded in 1803, according to Article 13 of the Reichsdeputationshauptschluss (formally the Hauptschluss der außerordentlichen Reichsdeputation, or "Principal Conclusion of the Extraordinary Imperial Delegation") other Swabian lands, including the Free Imperial City of Buchau, the Imperial Abbey of Buchau, the Imperial Abbeys of Marchtal and Neresheim, Ostrach, and other villages.
By 1790, the hereditary fiefs of the Thurn and Taxis family fueled the Imperial Reichspost to its greatest extent. The Austrian Netherlands and Tyrol were added to the Thurn and Taxis postal system. Due to the Napoleonic Wars, Karl Anselm's Imperial Reichspost gradually lost more and more postal districts beginning with the Austrian Netherlands, thus depriving the post of important sources of revenue. With the Treaty of Lunéville formalized on 9 February 1801, the Imperial Reichspost lost all postal districts in the Rhine region. After Prussia had been compensated for the loss of its left-bank territories by right bank areas in May 1802, Prussia took over the sovereignty over the postal services, and so the Imperial Reichspost lost further postal districts. Only under his son and successor, Karl Alexander, was the Thurn and Taxis family able to re-establish its postal system as the private company Thurn-und-Taxis-Post.
