Around 1150 there emerges in the Southeast of the empire a mighty territorial principality under the Babenbergs. Also belonging are the Duchy of Bavaria and the Marches of Austria. In 1156 Frederick I (Barbarossa) transfers this territory to the Guelfs as a fief. Heinrich II (Jasomirgott) of the Babenbergs is compensated for this loss: the Marches of Austria is raised to the level of the hereditary Duchy of Austria. Following this, Austria develops into a wide-reaching principality. Starting in 1230, the colors red-white-red becomes those of the national emblem under the so-called "binding shields."
