Charles II Francis of Austria (German: Karl II. Franz von Innerösterreich) (3 June 1540 – 10 July 1590) was an Archduke of Austria and ruler of Inner Austria (Styria, Carniola, Carinthia and Gorizia) from 1564. He was a member of the House of Habsburg. Unlike his brother, Emperor Maximilian II, Charles was a religious Catholic and promoted the Counter-Reformation, e.g. by inviting the Jesuits to his territory. However, in 1572, he had to make significant concessions to the Inner Austrian Estates in the Religious Pacifications of Graz, and 1578 and the Libellum of Bruck. In practice, this resulted in tolerance towards Protestantism. As the Inner Austrian line had to bear the major burden of the wars against the Turks, the fortress of Karlstadt/Karlovac in Croatia was founded in 1579 and named after him. Charles is also remembered as a benefactor of the arts and sciences. In particular, the composer Orlando di Lasso was one of his protégés, as was the music theorist Lodovico Zacconi. In 1573, Charles founded the Akademisches Gymnasium in Graz, the oldest secondary school in Styria. In 1580, Charles founded a stud for horses of Andalusian origin in Lipica, Slovenia, thereby playing a leading role in the creation of the Lipizzan breed. In 1585, Charles founded the University of Graz, which is named Karl-Franzens-Universität after him. He died at Graz in 1590.
