Leopold V, Duke of Austria

Leopold V, known as the Virtuous was a member of the House of Babenberg who reigned as Duke of Austria from 1177 and Duke of Styria within the Holy Roman Empire from 1192 until his death. The Georgenberg Pact resulted in Leopold being enfeoffed with Styria by Roman-German Emperor Frederick Barbarossa in 1193, which would lead to the eventual creation of modern Austria. Leopold was also known for his involvement in the Third Crusade where he fought in the Siege of Acre in 1191 and of his imprisonment of King Richard I in 1193 at Dürnstein Castle.
