The Habsburg dominions around 1200 in the area of modern-day Switzerland are shown as Habsburg, among the houses of Savoy, Zähringer and Kyburg.
The progenitor of the House of Habsburg may have been Guntram the Rich, a count in the Breisgau who lived in the 10th century, and forthwith farther back as the medieval Adalrich, Duke of Alsace, from the Etichonids from which Habsburg derives. His grandson Radbot of Klettgau founded the Habsburg Castle. That castle was the family seat during most of the 11th, 12th and 13th centuries. Giovanni Thomas Marnavich in his book "Regiae Sanctitatis Illyricanae Faecunditas" dedicated to Ferdinand III, wrote that the House of Habsburg is descended from the Roman emperor Constantine the Great, an invention common in ruling dynasties at the time.
In the 12th century, the Habsburgs became increasingly associated with the Staufer emperors, participating in the imperial court and the emperor's military expeditions; Werner II, Count of Habsburgdied fighting for Emperor Frederick I Barbarossa in Italy. This association helped them to inherit many domains as the Staufers caused the extinction of many dynasties, some of which the Habsburgs were heirs to. In 1198, Rudolf II, Count of Habsburg fully dedicated the dynasty to the Staufer cause by joining the Ghibellines and funded the Staufer emperor Frederick II's war for the throne in 1211. The emperor was made godfather to his newly born grandson, the future King Rudolf.
The Habsburgs expanded their influence through arranged marriages and by gaining political privileges, especially countship rights in Zürichgau, Aargau and Thurgau. In the 13th century, the house aimed its marriage policy at families in Upper Alsaceand Swabia. They were also able to gain high positions in the church hierarchy for their members. Territorially, they often profited from the extinction of other noble families such as the House of Kyburg.
By the second half of the 13th century, Count Rudolph I (1218–1291) had become an influential territorial lord in the area between the Vosges Mountains and Lake Constance. On 1 October 1273, he was elected as a compromise candidate as King of the Romans and received the name Rudolph I of Germany. He then led a coalition against King Ottokar II of Bohemia who had taken advantage of the Great Interregnum in order to expand southwards, taking over the respective inheritances of the Babenberg (Austria, Styria, Savinja) and of the Spanheim (Carinthia and Carniola). In 1278, Rudolph and his allies defeated and killed Ottokar at the Battle of Marchfeld, and the lands he had acquired reverted to the German crown. With the Georgenberg Pact of 1286, Rudolph secured for his family the duchies of Austria and Styria. The southern portions of Ottokar's former realm, Carinthia, Carniola, and Savinja, went to Rudolph's allies from the House of Gorizia.
Following Rudolph's death in 1291, Albert I's assassination in 1308, and Frederick the Fair's failure to secure the German/Imperial crown for himself, the Habsburgs temporarily lost their supremacy in the Empire. In the early 14th century, they also focused on the Kingdom of Bohemia. After Václav III's death on 4 August 1306, there were no male heirs remaining in the Přemyslid dynasty. Habsburg scion Rudolph I was then elected but only lasted a year. The Bohemian kingship was an elected position,and the Habsburgs were only able to secure it on a hereditary basis much later in 1626, following their reconquest of the Czech lands during the Thirty Years' War. After 1307, subsequent Habsburg attempts to gain the Bohemian crown were frustrated first by Henry of Bohemia (a member of the House of Gorizia) and then by the House of Luxembourg.
Instead, they were able to expand southwards: in 1311, they took over Savinja; after the death of Henry in 1335, they assumed power in Carniola and Carinthia; and in 1369, they succeeded his daughter Margaret in Tyrol. After the death of Albert III of Gorizia in 1374, they gained a foothold at Pazin in central Istria, followed by Trieste in 1382. Meanwhile, the original home territories of the Habsburgs in what is now Switzerland, including the Aargau with Habsburg Castle, were lost in the 14th century to the expanding Swiss Confederacy after the battles of Morgarten (1315) and Sempach(1386). Habsburg Castle itself was finally lost to the Swiss in 1415.
Through the forged document called privilegium maius (1358/59), Rudolf IV, Duke of Austria (1339–1365) introduced the title of Archduke to place the Habsburgs on a par with the Prince-electors of the Empire, since Emperor Charles IV had omitted to give them the electoral dignity in his Golden Bull of 1356. Charles, however, refused to recognize the title, as did his immediate successors.
Duke Ernest the Iron and his descendants unilaterally assumed the title "archduke". That title was only officially recognized in 1453 by Emperor Frederick III, the ruler of Austria himself.[19]Frederick himself used just "Duke of Austria", never Archduke, until his death in 1493. The title was first granted to Frederick's younger brother, Albert VI of Austria (died 1463), who used it at least from 1458. In 1477, Frederick granted the title archduke to his first cousin Sigismund of Austria, ruler of Further Austria. Frederick's son and heir, the future Maximilian I, Holy Roman Emperor, apparently only started to use the title after the death of his wife Mary of Burgundy in 1482, as Archduke never appears in documents issued jointly by Maximilian and Mary as rulers in the Low Countries (where Maximilian is still titled "Duke of Austria"). The title appears first in documents issued under the joint rule of Maximilian and Philip (his under-age son) in the Low Countries.
Archduke was initially borne by those dynasts who ruled a Habsburg territory, i.e., only by males and their consorts, appanages being commonly distributed to Cadets. These "junior" archdukes did not thereby become independent hereditary rulers, since all territories remained vested in the Austrian crown. Occasionally a territory might be combined with a separate gubernatorial mandate ruled by an archducal cadet. From the 16th century onward, archduke and its female form, archduchess, came to be used by all the members of the House of Habsburg (e.g., Queen Marie Antoinette of France was born Archduchess Maria Antonia of Austria).
