The Margraviate of Austria (German: Markgrafschaft Österreich) was a medieval frontier march, centered along the river Danube, between the river Enns and the Vienna Woods (Wienerwald), within the territory of modern Austrian provinces of Upper Austria and Lower Austria. It existed from c. 972 to 1156.It stemmed from the previous frontier structures, initially created for the defense of eastern Bavarian borders against the Avars, who were defeated and conquered during the reign of Charlemagne (d. 814). Throughout the Frankish period, the region was under jurisdiction of Eastern Frankish rulers, who held Bavaria and appointed frontier commanders (counts) in eastern regions.At the beginning of the 10th century, the region was raided by Magyars. They were defeated in the Battle of Lechfeld (955) and gradual German reconquest of the region began. By 972, newly retaken frontier regions along the river Danube were reorganized into a frontier county (margraviate) that became known as the Bavarian Eastern March (Latin: marcha orientalis) or Ostarrichi (German: Österreich). The first known margrave was Burkhard, who is mentioned in sources since 972.Since 976, it was governed by margraves from the Franconian noble House of Babenberg. The margraviate was protecting the eastern borders of the Holy Roman Empire, towards neighbouring Hungary. It became an Imperial State in its own right, when the Austrian margraves were elevated to Dukes of Austria in 1156.

The Archduchy of Austria (German: Erzherzogtum Österreich) was a major principality of the Holy Roman Empire and the nucleus of the Habsburg monarchy. With its capital at Vienna, the archduchy was centered at the Empire's southeastern periphery. Its present name originates from the Frankish term Oustrich – Eastern Kingdom (east of the Frankish kingdom). The archduchy developed out of the Bavarian Margraviate of Austria, elevated to the Duchy of Austria according to the 1156 Privilegium Minus by Emperor Frederick Barbarossa. The House of Habsburg came to the Austrian throne in Vienna in 1282 and in 1453 Emperor Frederick III, also the ruler of Austria, officially adopted the archducal title. From the 15th century onwards, all Holy Roman Emperors but one were Austrian archdukes and with the acquisition of the Bohemian and Hungarian crown lands in 1526, the Habsburg hereditary lands became the centre of a major European power.The archduchy's history as an imperial state ended with the dissolution of the Holy Roman Empire in 1806. It was replaced with the Lower and Upper Austria crown lands of the Austrian Empire.

The Duchy of Austria (German: Herzogtum Österreich) was a medieval principality of the Holy Roman Empire, established in 1156 by the Privilegium Minus, when the Margraviate of Austria (Ostarrîchi) was detached from Bavaria and elevated to a duchy in its own right. After the ruling dukes of the House of Babenberg became extinct in male line, there was as much as three decades of rivalry on inheritance and rulership, until the German king Rudolf I took over the dominion as the first monarch of the Habsburg dynasty in 1276. Thereafter, Austria became the patrimony and ancestral homeland of the dynasty and the nucleus of the Habsburg monarchy. In 1453, the archducal title of the Austrian rulers, invented by Duke Rudolf IV in the forged Privilegium Maius of 1359, was officially acknowledged by the Habsburg emperor Frederick III.
