The paper deals with the printed patent of the emperor Ferdinand II, dated on August 1,1628, with which the ruler ordered the Protestant nobility of three Inner Austrian lands: Styria, Carinthia and Carniola to convert to Catholicism or leave all his lands. Non-Catholic nobles were given a deadline of one year to convert or leave. Those who chose to leave, were obliged to sell their estates. However, since the Inner Austrian nobility did not join the rebellion of the provincial estates in other lands, the emperor exempted them from paying corresponding taxes to which the ruler was entitled due to the Augsburg Peace Treaty of 1555. The paper presents an introductory research, a diplomatic and critical transliteration and a Slovene translation ofthe discussed patent.
