Facts and Events
He was the youngest son of Charles II, Archduke of Austria (1540–1590) and Maria Anna of Bavaria (1551–1608). Born after his father's death, he was nicknamed "Charles the Posthumous". As the youngest of 15 children, he was destined for a career in the Church.
In 1602 he was appointed to a canonry of Salzburg Cathedral and in 1605 to a canonry of Passau. Further canonries in Trent and Brixen followed in 1606, and in Cologne Cathedral in 1618. These were for the most part absentee appointments that provided him with an income from ecclesiastical revenues. In 1608 he was appointed Prince-bishop of Breslau (Wrocław). In 1613 he became Bishop of Brixen and in 1619 he succeeded Maximilian III as Grandmaster of the Teutonic Knights.
Charles was a staunch Catholic. In 1609, he strongly protested against the decision of Rudolf II, Holy Roman Emperor to treat all religions equally in Silesia. After the Battle of White Mountain he forcefully reintroduced Catholicism in the Nysa Region. He founded a Jesuit college there in 1622.
