Hieronymus von Colloredo

Hieronymus Joseph Franz de Paula Graf Colloredo von Wallsee und Melz was Prince-Bishop of Gurk from 1761 to 1772 and Prince-Archbishop of Salzburg from 1772 until 1803, when the prince-archbishopric was secularized. After secularization, Colloredo fled to Vienna and remained the non-resident archbishop of Salzburg, bereft of temporal power, until his death in 1812. He is most famously known as a patron and employer for Mozart.
