Albert III with the Pigtail (1349 - 1395) was the Archduke of Austria (1365 - 1395), and Duke of Carinthia and Styria, and Margrave of Carniola (1365 - 1379). Albert was the third son of Duke Albert II the Wise of the House of Habsburg. After his two elder brothers died without heirs, Albert became the ruler of the Austrian domain in 1365. After several years of quarelling, Albert split the Austrian domain with his brother Leopold in 1379 at the Treaty of Neuburg with Albert receiving Austria and Leopold receiving the rest. Albert's reign was beneficial to Austria. As a keen scholar he promoted the arts and science and he enlarged the University of Vienna. Albert went on Crusade in 1377 against the pagan Lithuanians and Samogitians in the Baltics of northern Europe.
