Карл Александр
Karl Alexander studied at the Universities of Strasbourg, Würzburg, and Mainz and then subsequently went on a European tour. In 1797, he was appointed successor to his ailing father's position as "Prinzipalkommissar" at the Perpetual Imperial Diet in Regensburg. Karl Alexander also worked for the Thurn and Taxis postal empire, operating during a decline due to the gradual loss of territory as a result of the Napoleonic Wars.
