Austrian Empire

The Austrian Empire (Kaisertum Österreich) was a modern era successor empire founded on a remnant of the Holy Roman Empire, which was centered on what is today's Austria and which officially lasted from 1804 to 1867. It was followed by the Empire of Austria-Hungary, which was proclaimed after declaring the Emperor of Austria also King of Hungary, a diplomatic move that elevated Hungary's status within the Austrian Empire as a result of the Austro-Hungarian Compromise of 1867. The Austro-Hungarian Empire (1867 to 1918) was itself dissolved by the victors at the end of World War I and broken into separate new states.

The term "Austrian Empire" is also used for the Habsburg possessions before 1804, which had no official collective name, although Austria is more frequent; the term of Austria-Hungary has also been used.

The Austrian Empire was founded by the Habsburg monarch Holy Roman Emperor Francis II (who became Emperor Francis I of Austria), as a state comprising his personal lands within and outside of the Holy Roman Empire.

This was a reaction to Napoleon Bonaparte's proclamation of the First French Empire in 1804.

Austria and some parts of the Holy Roman Empire then took the field against France and its German allies during the Third Coalition which led to the crushing defeat at Austerlitz in early December 1805. By the fourth of that same month, a cease fire was in place and  peace talks were being conducted nearby.

Subsequently, Francis II agreed to the humiliating Treaty of Pressburg (December 1805), which in practice meant dissolution of the long-lived Holy Roman Empire with a reorganization of the lost German territories under a Napoleonic imprint into a precursor state of what became modern Germany, those possessions nominally having been part of the Holy Roman Empire within the present boundaries of Germany, as well as other measures weakening Austria and the Habsburgs in other ways. Certain Austrian holdings in Germany were passed to French allies—the King of Bavaria, the King of Württemberg and the Elector of Baden. Austrian claims on those German states were renounced without exception.

One consequence of that was eight months later on 6 August 1806, Francis II dissolved the Holy Roman Empire, due to the formation of the Confederation of the Rhine by France; as he did not want Napoleon to succeed him. This action was unrecognized by George III of the United Kingdom who was also the Elector of Hanover who had also lost his German territories around Hanover to Napoleon. The English claims were settled by the creation of the Kingdom of Hanover which was held by George's British heirs until Queen Victoria's ascension, after which point it split into the British and Hanoverian royal families.

Although the office of Holy Roman Emperor was elective, the House of Habsburg had held the title since 1440 (with one brief interruption) and Austria was the core of their territories.

After Austria was defeated in the Austro-Prussian War of 1866, and left the German Confederation, the Austrian Empire was transformed into the Austro-Hungarian Empire by the Austro-Hungarian Compromise of 1867, which granted Hungary and the Hungarian lands equal status to the rest of Austria as a whole.

Creation
Changes shaping the nature of the Austrian Empire took place during conferences in Rastatt (1797–1799) and Regensburg (1801–1803). On 24 March 1803, the Imperial Recess (Reichsdeputationshauptschluss) was declared, which greatly reduced the number of clerical territories from 81 to only 3 and imperial cities from 51 to 6. This measure was aimed at replacing the old constitution of the Holy Roman Empire, but the actual consequence of the Imperial Recess was the end of the Holy Roman Empire. Taking this significant change into consideration, Francis II created the title Emperor of Austria, for himself and his successors, abandoning the title of Holy Roman Emperor later in 1806.

The fall and dissolution of the Empire was accelerated by French intervention in the Empire in September 1805. On 20 October 1805, an Austrian army led by general Karl Mack von Leiberich was defeated by French armies near the town of Ulm. The French victory resulted in the capture of 20,000 Austrian soldiers and many cannons. Napoleon’s army won another victory in the Battle of Austerlitz on 2 December 1805. In light of those events, Francis was forced to negotiate with the French from 4 December to 6 December 1805. These negotiations were concluded by an armistice on 6 December 1805.

The French victories encouraged rulers of certain imperial territories to assert their formal independence from the Empire. On 10 December 1805, the prince-elector Duke of Bavaria proclaimed himself King, followed by the elector Duke of Württemberg on 11 December. Finally, on 12 December, the Margrave of Baden was given the title of Grand Duke. In addition, each of these new countries signed a treaty with France and became French allies. The Treaty of Pressburg between France and Austria, signed in Pressburg (today Bratislava, Slovakia) on 26 December, enlarged the territory of Napoleon's German allies at the expense of defeated Austria.

On 12 July 1806, the Confederation of the Rhine was established comprising 16 sovereigns and countries. This confederation, under French influence, put an end to the Holy Roman Empire. On 6 August 1806, even Francis recognized the new state of things and proclaimed the dissolution of the Holy Roman Empire.

When, on 11 August 1804, Francis II assumed the title of first Emperor of Austria, the empire spanned from present-day Italy to present-day Poland and to the Balkans. The multi-national makeup of the empire is illustrated by the fact that its population included Germans, Czechs, Poles, Romanians, Hungarians, Italians, Ukrainians, Croats, Slovaks, Serbs, Slovenes and numerous smaller nationalities. The emperor ruled Austria as the namesake, but also held the title of King of Hungary, Bohemia, Croatia, Slavonia and Dalmatia, leading to the Empire's multi-national army being styled the Kaiserlich-königliche Armee (Imperial-Royal Army). The Empire had a centralist structure, although some degree of autonomy was left to Hungary which was ruled by its own Diet, and to Tyrol.

Foreign policy
The years 1804–1815 in Austrian foreign policy were significantly determined by the Napoleonic Wars. After Prussia signed a peace treaty with France on 5 April 1795, Austria was forced to carry the main burden of war with the French Republic/Empire for almost ten years. This situation led to a distortion of the Austrian economy contributing to the Austrians perceiving the war in a highly unpopular manner. With regard to the mentioned mood, Emperor Francis II refused to join in the next war against Napoleonic France for a long time. On the other hand, Francis II did not abandon a possibility of revenge on France and therefore he entered into a secret military agreement with the Russian Empire in November 1804. This convention was to assure mutual cooperation between Austria and Russia in the case of a new war against France.

An apparent unwillingness of Austria to join the Third Coalition was overcome by British subsidies. A decisive defeat at Battle of Austerlitz put an end to Austrian membership in the Third Coalition. Although the Austrian budget suffered from wartime expenditures and its international position was significantly undermined, the humiliating Treaty of Pressburg provided plenty of time to strengthen the army and economy. Moreover, an ambitious Archduke Charles together with Johann Philipp von Stadion pursued a new war with France.

Archduke Charles of Austria served as the Head of the Council of War and Commander in Chief of the Austrian army. Endowed with the enlarged powers, he reformed the Austrian Army to preparedness for another war. Johann Philipp von Stadion, the foreign minister, personally hated Napoleon due to an experience of confiscation of his possessions in France by Napoleon. In addition, the third wife of Francis II, Marie Ludovika of Austria-Este, agreed with Stadion's efforts to begin a new war. Klemens Wenzel von Metternich, located in Paris, called for careful advance in the case of the war against France. The defeat of French army at the Battle of Bailén in Spain on 27 July 1808 triggered the war. On 9 April 1809, an Austrian force of 170,000 men attacked Bavaria.

Despite military defeats—especially high magnitude losses like those at the Battles of Marengo, Ulm, Austerlitz and Wagram—and consequently lost territory throughout the Revolutionary and Napoleonic Wars (the Treaties of Campo Formio in 1797, Pressburg in 1806, and Schönbrunn in 1809), Austria played a decisive part in the overthrow of Napoleon in the campaigns of 1813–14.

The latter period of Napoleonic Wars featured Metternich exerting a large degree of influence over foreign policy in the Austrian Empire, a matter nominally decided by the Emperor. Metternich initially supported an alliance with France, arranging the marriage between Napoleon and the Francis II's daughter, Marie-Louise; however, by the 1812 campaign, he had realised the inevitability of Napoleon's downfall and took Austria to war against France. Metternich's influence at the Congress of Vienna was remarkable, and he became not only the premier statesman in Europe but virtual ruler of the Empire until 1848—the Year of Revolutions—and the rise of liberalism equated to his political downfall.
