Emperor Rudolf IV

Rudolf IV of Habsburg, known as "the Founder" (1339-1365), was an important ruler of Austria.

He was the son of Albert II of Habsburg and Joanna of Pfirt.

He became Duke of Austria, Styria, and Carinthia in 1358, upon his father's death. Although he never obtained the title of Emperor of the Holy Roman Empire, he proclaimed himself "Archduke" in 1358, a title that was officially recognized only in 1453.
One of his most enduring contributions was the founding of the University of Vienna in 1365, the oldest university in the German-speaking world.
Under his reign, Vienna developed significantly. Rudolf IV initiated major construction projects, including the enhancement of St. Stephen's Cathedral, making it one of the city's main symbols.
Rudolf IV also commissioned the drafting of the "Privilegium Maius," a document that expanded the rights and privileges of the Dukes of Austria, inspired by the Privilegium Minus of 1156. Although considered a historical forgery, it was crucial in consolidating the power of the Habsburgs.

He married Catherine of Luxembourg, daughter of Emperor Charles IV, strengthening the political ties between the two dynasties.

Unfortunately, he died prematurely in 1365 in Milan, at only 26 years old. His early death interrupted many of his projects, but his impact on the development of Vienna and Austria remained significant.

Rudolf IV is remembered for his innovative spirit and for laying the foundations for the future greatness of the Habsburgs and Vienna as a cultural and political center.
