Duchy of Austria in the context of "Second Austrian Republic"

The Habsburg monarchy, also known as Habsburg Empire, or Habsburg Realm (/ˈhæpsbɜːrɡ/), and Danube Monarchy, was the collection of empires, kingdoms, duchies, counties and other polities (composite monarchy) that were ruled by the House of Habsburg. From 1804 it was referred to as the Austrian Empire, and from 1867 as Austria-Hungary.

The history of the Habsburg monarchy can be traced back to the election of Rudolf I as King of Germany in 1273 and his acquisition of the Duchy of Austria for the Habsburgs in 1282. In 1482, Maximilian I acquired the Netherlands through marriage. Both realms passed to his grandson and successor, Charles V, who also inherited the Spanish throne and its colonial possessions, and thus came to rule the Habsburg empire at its greatest territorial extent. The abdication of Charles V in 1556 led to a division within the dynasty between his son Philip II of Spain and his brother Ferdinand I, who had served as his lieutenant and the elected king of Hungary, Croatia and Bohemia. The Spanish branch (which held all of Iberia, the Netherlands, and lands in Italy) became extinct in the male line in 1700, but continued through the female line through the House of Bourbon. The Austrian branch (which ruled the Holy Roman Empire, Hungary, Bohemia and various other lands) was itself split into different branches in 1564 but reunited 101 years later. It became extinct in the male line in 1740, but continued through the female line as the House of Habsburg-Lorraine.

William Tell (German: Wilhelm Tell, pronounced [ˈvɪlhɛlm ˈtɛl] ; French: Guillaume Tell; Italian: Guglielmo Tell; Romansh: Guglielm Tell) is a legendary folk hero of Switzerland. He is known for shooting an apple off his son's head.

According to the legend, Tell was an expert mountain climber and marksman with a crossbow who assassinated Albrecht Gessler, a tyrannical reeve of the Austrian dukes of the House of Habsburg positioned in Altdorf, in the canton of Uri. Tell's defiance and tyrannicide encouraged the population to open rebellion and to make a pact against the foreign rulers with neighbouring Schwyz and Unterwalden, marking the foundation of the Swiss Confederacy, of which Tell is consequently considered the father.

The Archduchy of Austria (Latin: Archiducatus Austriae; 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 onward, 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 history of Austria covers the history of Austria and its predecessor states. In the late Iron Age Austria was occupied by people of the Hallstatt Celtic culture (c. 800 BC), they first organized as a Celtic kingdom referred to by the Romans as Noricum, dating from c. 800 to 400 BC. At the end of the 1st century BC, the lands south of the Danube became part of the Roman Empire. In the Migration Period, the 6th century, the Bavarii, a Germanic people, occupied these lands until it fell to the Frankish Empire established by the Germanic Franks in the 9th century. In the year 976 AD, the first state of Austria formed. The name Ostarrîchi (Austria) has been in use since 996 AD when it was a margravate of the Duchy of Bavaria and from 1156 an independent duchy (later archduchy) of the Holy Roman Empire (962–1806).

Austria was dominated by the House of Habsburg and House of Habsburg-Lorraine from 1273 to 1918. In 1806, when Emperor Francis II of Austria dissolved the Holy Roman Empire, Austria became the Austrian Empire, and was also part of the German Confederation until the Austro-Prussian War of 1866. In 1867, Austria formed a dual monarchy with Hungary: the Austro-Hungarian Empire. When this empire collapsed after the end of World War I in 1918, Austria was reduced to the main, mostly German-speaking areas of the empire (its current frontiers), and adopted the name, the Republic of German-Austria. However, union with Germany and the chosen country name were forbidden by the Allies at the Treaty of Versailles. This led to the creation of the First Austrian Republic (1919–1933).

The Saxon Eastern March (German: Sächsische Ostmark) was a march of the Holy Roman Empire from the 10th until the 12th century. The term "eastern march" stems from the Latin term marchia Orientalis and originally could refer to either a march created on the eastern frontier of the East Frankish duchy of Saxony or another on the eastern border of the Duchy of Bavaria: the Bavarian marchia Orientalis (documented as Ostarrîchi in 996), corresponding to later Austria.

Stephen III (Hungarian: III. István, Croatian: Stjepan III.; Slovak: Štefan III.; summer of 1147 – 4 March 1172) was King of Hungary and Croatia between 1162 and 1172. He was crowned king in early June 1162, shortly after the death of his father, Géza II. However, his two uncles, Ladislaus and Stephen, who had joined the court of the Byzantine Empire, challenged his right to the crown. Only six weeks after his coronation, the Byzantine Emperor Manuel I Komnenos launched an expedition against Hungary, forcing the Hungarian lords to accept Ladislaus' rule. Stephen sought refuge in Austria, but returned and seized Pressburg (now Bratislava in Slovakia). Ladislaus, who died on 14 January 1163, was succeeded by Stephen's younger uncle and namesake, Stephen IV, without resistance, but his rule was unpopular. The young Stephen defeated his uncle on 19 June 1163 and expelled him from Hungary.

Stephen IV attempted to regain his throne with Emperor Manuel I's support, but the latter made peace with Stephen III. He agreed to send his younger brother, Béla, to Constantinople and to allow the Byzantines to seize Béla's duchy, which included Croatia, Dalmatia and Sirmium. In an attempt to recapture these territories, Stephen III waged wars against the Byzantine Empire between 1164 and 1167, but could not defeat the Byzantines.

The House of Babenberg was a noble dynasty of Austrian Dukes and Margraves. Descending from the Popponids and originally from Bamberg in the Duchy of Franconia (present-day Bavaria), the Babenbergs ruled the imperial Margraviate of Austria from its creation in 976 AD until its elevation to a duchy in 1156, and from then until the extinction of the line in 1246, whereafter they were succeeded by the House of Habsburg.
