The head of the House of Habsburg was often elected Holy Roman Emperor until the Empire's dissolution in 1806. The two entities were never coterminous, as the Habsburg Monarchy covered many lands beyond the Holy Roman Empire, and most of the Empire was ruled by other dynasties. The Habsburg Monarchy did not usually include all the territories ruled by the Habsburgs. The senior branch ruled Spain until 1700, but it is not usually included in the definition of "Habsburg Monarchy" after the reign of Charles V, who divided the dynasty between its Austrian and Spanish branches upon his abdication in 1556.
Names of the territory that (with some exceptions) finally became Austria-Hungary:
Habsburg monarchy or Austrian monarchy (1526–1867): This was an unofficial, but very frequent name – even at that time. The entity had no official name. Note that technically the term "Habsburg monarchy" can also refer to the period 1276–1918 when the Habsburgs ruled in the monarchy (archduchy) centred in present-day Austria and "Austrian monarchy" can refer to the monarchy centered in present-day Austria 1156–1867, but both terms are usually not used this way.
Austrian Empire (1804–1867): This was the official name. Note that the German version is Kaisertum Österreich, i.e. the English translation empire refers to a territory ruled by an emperor, not just to a "widespreading domain", more accurately the "Emperordom of Austria".
Austria-Hungary or Austro-Hungarian Empire (1867–1918): This was the official name. An unofficial popular name was the Danubian Monarchy (German: Donaumonarchie) also often used was the term Doppel-Monarchie ("Double Monarchy") meaning two states under one crowned ruler.
Crownlands or crown lands (Kronländer) (1849–1918): This is the name of all the individual parts of the Austrian Empire (since 1849) and then of Austria-Hungary. The Kingdom of Hungary (more exactly the Lands of the Hungarian Crown) was not considered a "crownland" after the establishment of Austria-Hungary 1867, so that the "crownlands" became identical with what was called the Kingdoms and Lands represented in the Imperial Council (Die im Reichsrate vertretenen Königreiche und Länder).
The Hungarian parts of the Empire were called "Lands of the Holy Hungarian Crown of Saint Stephen" or "Lands of Holy (St.) Stephen's Crown" (Länder der Heiligen Stephans Krone). The Bohemian (Czech) Lands were called "Lands of the St. Wenceslaus' Crown" (Länder der Wenzels-Krone).
Names of some smaller territories:
Austrian lands (Österreichische Länder) or "Archduchies of Austria" (Erzherzogtümer von Österreich) - Lands up and below the Enns (ober und unter der Enns) (996–1918): This is the historical name of the parts of the Archduchy of Austria that became the present-day Republic of Austria (Republik Österreich) on 12 November 1918 (after Emperor Charles I had abdicated the throne). Modern day Austria is a semi-federal republic of nine states (Bundesländer) that are: Lower Austria, Upper Austria, Tyrol, Styria, Salzburg, Carinthia, Vorarlberg and Burgenland and the Capital of Vienna that is a state of its own. Burgenland came to Austria in 1921 from Hungary. Salzburg finally became Austrian in 1816 after Napoleonic wars (before it was ruled by prince-archbishops of Salzburg as a sovereign territory).
Vienna, Austria's capital became a state January 1, 1922, after being residence and capital of the Austrian Empire (Reichshaupt und Residenzstadt Wien) for the Habsburg monarchs for centuries. Upper and Lower Austria, historically, were split into "Austria above the Enns" and "Austria below the Enns" (the Enns river is the state-border between Upper- and Lower Austria). Upper Austria was enlarged after the Treaty of Teschen (1779) following the "War of the Bavarian Succession" by the so-called Innviertel ("Inn Quarter"), formerly part of Bavaria.
Hereditary Lands (Erblande or Erbländer; mostly used Österreichische Erblande) or German Hereditary Lands (in the Austrian monarchy) or Austrian Hereditary Lands (Middle Ages – 1849/1918): In a narrower sense these were the "original" Habsburg Austrian territories, i.e. basically the Austrian lands and Carniola (not Galicia, Italian territories or the Austrian Netherlands).
In a wider sense the Lands of the Bohemian Crown were also included in (from 1526; definitely from 1620/27) the Hereditary lands. The term was replaced by the term "Crownlands" (see above) in the 1849 March Constitution, but it was also used afterwards.
The Erblande also included lots of small and smallest territories that were principalities, duchies or counties etc. some of them can namely be found in the reigning titles of the Habsburg monarchs like Graf (Earl/Count of) von Tyrol etc.
The territories ruled by the branch changed over the centuries, but the core always consisted of four blocs:
The Hereditary Lands, which covered most of the modern states of Austria and Slovenia, as well as territories in northeastern Italy and (before 1797) southwestern Germany. To these were added in 1779 the Inn Quarter of Bavaria; and in 1803 the Bishoprics of Trent and Brixen. The Napoleonic Wars caused disruptions where many parts of the Hereditary lands were lost, but all these, along with the former Archbishopric of Salzburg, which had previously been temporarily annexed between 1805 and 1809, were recovered at the peace in 1815, with the exception of the Vorlande. The Hereditary provinces included:
The County of Tyrol (although the Bishoprics of Trent and Brixen dominated what would become the South Tyrol before 1803);
The Vorarlberg (actually a collection of provinces, only united in the 19th century);
The Vorlande, a group of territories in Breisgau and elsewhere in southwestern Germany lost in 1801 (although the Alsatian territories (Sundgau) which had formed a part of it had been lost as early as 1648);
Vorarlberg and the Vorlande were often grouped together as Further Austria and mostly ruled jointly with Tyrol.
The Kingdom of Hungary – two thirds of the former territory that was administered by the medieval Kingdom of Hungary was conquered by the Ottoman Empire and the Princes of vassal Ottoman Transylvania, while the Habsburg administration was restricted to the western and northern territories of the former kingdom, which remained to be officially referred as the Kingdom of Hungary. In 1699, at the end of the Ottoman-Habsburg wars, one part of the territories that were administered by the former medieval Kingdom of Hungary came under Habsburg administration, with some other areas being picked up in 1718 (some of the territories that were part of medieval kingdom, notably those in the south of the Sava and Danube rivers, remained under Ottoman administration).
The boundaries of some of these territories varied over the period indicated, and others were ruled by a subordinate (secundogeniture) Habsburg line. The Habsburgs also held the title of Holy Roman Emperor between 1438 and 1740, and again from 1745 to 1806.
The various Habsburg possessions never really formed a single country—each province was governed according to its own particular customs. Until the mid 17th century, all of the provinces were not even necessarily ruled by the same person—junior members of the family often ruled portions of the Hereditary Lands as private apanages. Serious attempts at centralization began under Maria Theresa and especially her son Joseph II in the mid to late 18th century, but many of these were abandoned following large scale resistance to Joseph's more radical reform attempts, although a more cautious policy of centralization continued during the revolutionary period and the long Metternichianperiod which followed.
An even greater attempt at centralization began in 1849 following the suppression of the various revolutions of 1848. For the first time, ministers tried to transform the monarchy into a centralized bureaucratic state ruled from Vienna. The Kingdom of Hungary, in particular, ceased to exist as a separate entity, being divided into a series of districts. Following the Habsburg defeats in the Wars of 1859 and 1866, this policy was abandoned, and after several years of experimentation in the early 1860s, the famous Austro-Hungarian Compromise of 1867 was arrived at, by which the so-called Dual Monarchy of Austria-Hungary was set up. In this system, the Kingdom of Hungary was given sovereignty and a parliament, with only a personal union and a joint foreign and military policy connecting it to the other Habsburg lands. Although the non-Hungarian Habsburg lands, often, but erroneously, referred to as "Austria," received their own central parliament (the Reichsrat, or Imperial Council) and ministries, as their official name – the "Kingdoms and Lands Represented in the Imperial Council" – shows that they remained something less than a genuine unitary state. When Bosnia and Herzegovina were annexed (after a long period of occupation and administration), they were not incorporated into either half of the monarchy. Instead, they were governed by the joint ministry of finance.
Austria-Hungary collapsed under the weight of the various unsolved ethnic problems that came to a head with its defeat in World War I. In the peace settlement that followed, significant territories were ceded to Romania and Italy, new republics of Austria (the German-Austrian territories of the Hereditary lands) and Hungary (the Magyar core of the old kingdom) were created, and the remainder of the monarchy's territory was shared out among the new states of Poland, Kingdom of Serbs, Croats and Slovenes (later Yugoslavia), and Czechoslovakia.
Habsburg territories outside the Habsburg Monarchy
Habsburg territories in 1700. The Habsburg Monarchy is shown in yellow, while the territories of the senior Spanish Habsburgs are shown in red.
The Habsburg monarchy should not be confused with various other territories ruled at different times by members of the Habsburg dynasty. The senior Spanish line of the Habsburgs ruled over Habsburg Spain and various other territories from 1516 until it became extinct in 1700. A junior line ruled over Tuscany between 1765 and 1801, and again from 1814 to 1859. While exiled from Tuscany, this line ruled at Salzburg from 1803 to 1805, and in Würzburg from 1805 to 1814. Another line ruled the Vorlande from 1803 to 1805, and Modena from 1814 to 1859, while Empress Marie Louise, Napoleon's second wife and the daughter of Austrian Emperor Francis, ruled over the Duchy of Parma between 1814 and 1847. Also, the Second Mexican Empire, from 1863 to 1867, was headed by Maximilian I of Mexico, the brother of Emperor Franz Josef of Austria.
