Query: When did Austria split?
In the immediate aftermath of World War II, Austria was divided into four occupation zones and jointly occupied by the United States, the Soviet Union, the United Kingdom, and France. Vienna was similarly subdivided but the central district was collectively administered by the Allied Control Council.
If Greater Germany was to prevail, the crown would necessarily have to go to Franz Joseph, who had no desire to cede it in the first place to anyone else. On the other hand, if the idea of a smaller Germany won out, the German crown could of course not possibly go the Emperor of Austria, but would naturally be offered to the head of the largest and most powerful German state outside of Austria—the King of Prussia. The contest between the two ideas, quickly developed into a contest between Austria and Prussia. After Prussia decisively won the Seven Weeks War, this question was solved; Austria lost no territories as long as they remained out of German affairs.
The split between the Albertinian and Leopoldinian lines of the Habsburg family and the Austrian lands enfeebled the dynasty's position. The Albertinian archduke Albert V of Austria was elected King of the Romans in 1438. Nevertheless, he died one year later and the line finally became extinct by the death of his son Ladislaus the Posthumous in 1457. The territories were inherited by the Leopoldian archduke Frederick V of Inner Austria, Albert's successor as King of the Romans and from 1452 also Holy Roman Emperor. Finally in 1490, all Habsburg territories were reunified, when Archduke Sigismund handed over the rulership of Tyrol and Further Austria ('Upper Austria') to Emperor Frederick's son King Maximilian I.
Due to external and internal problems, reforms seemed inevitable to secure the integrity of the Habsburg Empire. Major Austrian military defeats (such as the 1866 Battle of Königgrätz) forced Austrian emperor Franz Joseph to concede internal reforms. To appease Hungarian separatism, the emperor made a deal with Hungary (the Austro-Hungarian Compromise of 1867, negotiated by Ferenc Deák) by which the dual monarchy of Austria–Hungary came into existence. The two realms were governed separately by two parliaments from two capitals, with a common monarch and common external and military policies. Economically, the empire was a customs union. The first prime minister of Hungary after the Compromise was Count Gyula Andrássy. The old Hungarian Constitution was restored, and Franz Joseph was crowned as King of Hungary. Romanian intellectuals issued the Blaj Pronouncement in protest of the Compromise.
The high command under Paul von Hindenburg and Erich Ludendorff increasingly controlled the country, but in October after the failed offensive in spring 1918, the German armies were in retreat, allies Austria-Hungary and the Ottoman Empire had collapsed, and Bulgaria had surrendered. The Empire collapsed in the November 1918 Revolution with the abdications of its monarchs. This left a postwar federal republic and a devastated and unsatisfied populace, which later led to the rise of Adolf Hitler and Nazism.
Meanwhile, on November 12, 1918, the Provisional National Assembly of German Austria declared the country a republic. On April 3, 1919 the Constitutional National Assembly elected in February passed the Hapsburg Law which stipulated members of the former ruling family could only live in Austria if they cancelled their membership to the Habsburg Dynasty with its monarchial aspirations and if they declared themselves loyal citizens of the republic. Maximilian obviously preferred to live outside of Austria, following the example of the last imperial couple.
Before 1918, both countries were part of Austria–Hungary. However, after the Ausgleich of 1867 Czechia belonged to the Austrian Empire while Slovakia belonged to the administratively separate Kingdom of Hungary, and between 1918 and December 31, 1992, both countries were part of Czechoslovakia. 
Both countries established diplomatic relations on January 1, 1993. These international relations are usually referred to or described as "very good", "cordial", and "above standard" in the media. When a Czech or Slovak president is inaugurated, very often his first international visit is to the former part of the common country. The same custom applies to newly elected prime ministers of the Czech Republic and Slovakia.
The pretext for the conflict was found in the dispute between Prussia and Austria over the administration of Schleswig-Holstein, which the two of them had conquered from Denmark and agreed to jointly occupy at the end of the Second Schleswig War in 1864. When Austria brought the dispute before the German Diet and also decided to convene the Diet of Holstein, Prussia declared that the Gastein Convention had thereby been nullified and invaded Holstein. When the German Diet responded by voting for a partial mobilization against Prussia, Bismarck claimed that the German Confederation was ended. Crown Prince Frederick "was the only member of the Prussian Crown Council to uphold the rights of the Duke of Augustenburg and oppose the idea of a war with Austria which he described as "fratricide"". Although he supported unification and the restoration of the medieval empire, "Fritz could not accept that war was the right way to unite Germany."
The German Confederation ended as a result of the Austro-Prussian War of 1866 between Austrian Empire and its allies on one side and the Kingdom of Prussia and its allies on the other. The Confederation had 34 members immediately before its dissolution. In the Prague peace treaty, on 23 August 1866, Austria had to accept that the Confederation was dissolved. The following day, the remaining member states confirmed the dissolution. The treaty allowed Prussia to create a new (a new kind of federation) in the North of Germany. The South German states were allowed to create a South German Confederation but this did not come into existence.
Anschluss ( "joining") refers to the annexation of Austria into Nazi Germany on 12 March 1938. The word's German spelling, until the German orthography reform of 1996, was Anschluß and it was also known as the Anschluss Österreichs (, ).
Only after Prussian Chancellor Otto von Bismarck gradually built a unified German state under the Prussian royal house of Hohenzollern did "Kleinstaaterei" largely end in 1871 with the founding of the German Empire. (The only surviving petty states—Luxembourg and Liechtenstein—lie at the periphery of the German-speaking world.) The founding of the German Empire created a largely German nation-state. While the German Empire excluded the partly German but multinational Habsburg domains of Austria–Hungary, it included a substantial Polish minority in parts of eastern Prussia and other minorities along its northern and western borders. The unification of the German Empire put Germany on the map as a major European power, albeit too late to become a major colonial presence. Internally in the nation some of these fragmented boundaries and small political units continued to exist until the modern States of Germany were established in the Federal Republic after World War II.
The Holy Roman Empire, ruled by the Habsburg dynasty, gave way to the Empire of Austria between 1804 and 1806. The last Holy Roman Emperor, Franz II, was proclaimed Emperor Franz I of Austria. His daughter, the Archduchess Maria Louise, was Napoleon’s second wife and Empress Consort, and the mother of Napoleon’s only legitimate son and heir, Napoleon, Duke of Reichstadt. With the collapse of Napoleon’s empire, Imperial Austria regained its traditional control of Lombardy as the Kingdom of Lombardy–Venetia.
Franz Joseph I or Francis Joseph I (Franz Joseph Karl; 18 August 1830 – 21 November 1916) was Emperor of Austria, King of Hungary, and monarch of many other states of the Austro-Hungarian Empire, from 2 December 1848 to his death. From 1 May 1850 to 24 August 1866 he was also President of the German Confederation. He was the longest-reigning Emperor of Austria and King of Hungary, as well as the third-longest-reigning monarch of any country in European history, after Louis XIV of France and Johann II of Liechtenstein.
By the 1859 Treaty of Zurich which ended the Austro-Sardinian War, Austria ceded Lombardy, including Crema, to France, who then immediately ceded it to Sardinia. This formed part of the "Risorgimento", which saw Sardinia become the Kingdom of Italy in 1861. In 1946, the Kingdom became the modern Italian Republic.
The first Austrian Emperor was the last Holy Roman Emperor Francis II. In the face of aggressions by Napoleon, Francis feared for the future of the Holy Roman Empire. He wished to maintain his and his family's Imperial status in the event that the Holy Roman Empire should be dissolved, as it indeed was in 1806 when an Austrian-led army suffered a humiliating defeat at the Battle of Austerlitz. After which, the victorious Napoleon proceeded to dismantle the old "Reich" by severing a good portion from the empire and turning it into a separate Confederation of the Rhine. With the size of his imperial realm significantly reduced, Francis II, "Holy Roman Emperor" became Francis I, "Emperor of Austria". The new imperial title may have sounded less prestigious than the old one, but Francis' dynasty continued to rule from Austria and a Habsburg monarch was still an emperor ("Kaiser"), and not just merely a king ("König"), in name.
The empire was dissolved on 6 August 1806, when the last Holy Roman Emperor Francis II (from 1804, Emperor Francis I of Austria) abdicated, following a military defeat by the French under Napoleon at Austerlitz (see Treaty of Pressburg). Napoleon reorganized much of the Empire into the Confederation of the Rhine, a French satellite. Francis' House of Habsburg-Lorraine survived the demise of the empire, continuing to reign as Emperors of Austria and Kings of Hungary until the Habsburg empire's final dissolution in 1918 in the aftermath of World War I.
Austria began as a small march and was later elevated to a duchy, then archduchy. The house of Babenberg and later the Habsburg dynasty were the margraves, dukes and later archdukes of this fiefdom. After the death of the last Babenberg duke, Frederick II in 1246, King Ottokar II of Bohemia took over for a while. He was, however, defeated by the King of the Romans Rudolf of Habsburg in 1278, with the help of his sons Albert and Rudolf. Rudolf then installed his son Albert as Duke of Austria. The enthronement ceremony of the new Archduke of Austria was not an actual coronation, but more a ceremony of homage by the estates. In the German language, this ceremony is called the . The estates in parliament swore obedience to their new ruler, and he in turn guaranteed their rights and upheld their privileges. However, in this ceremony sovereign insignia were also used.
In November 1918, with internal revolution, a stalemated war, Bulgaria and the Ottoman Empire suing for peace, Austria-Hungary falling apart from multiple ethnic tensions, and pressure from the German high command, the Kaiser and all German ruling princes abdicated. On 9 November 1918, the Social Democrat Philipp Scheidemann proclaimed a Republic, in cooperation with the business and middle classes, not the revolting workers. The new government led by the German Social Democrats called for and received an armistice on 11 November 1918; in practice it was a surrender, and the Allies kept up the food blockade to guarantee an upper hand. The war was over; the history books closed on the German Empire. It was succeeded by the democratic, yet flawed, Weimar Republic.
The evolution of the Croatia–Serbia border began in 1699 with the Treaty of Karlowitz, transferring Slavonia and a portion of Syrmia from the Ottoman Empire to the Habsburg Monarchy at the conclusion of the Great Turkish War. The rest of Syrmia was transferred to the Habsburg Monarchy through the Treaty of Passarowitz in 1718. The transferred territories were organised within the monarchy into the Kingdom of Slavonia, with its eastern border established at the Danube, and the defensive belt of Military Frontier stretching along the Sava River, governed directly from Vienna.
The Austro-Prussian War or Seven Weeks' War (also known as the Unification War, the War of 1866, or the Fraternal War, in Germany as the German War, and also by a variety of other names) was a war fought in 1866 between the Austrian Empire and the Kingdom of Prussia, with each also being aided by various allies within the German Confederation. Prussia had also allied with the Kingdom of Italy, linking this conflict to the Third Independence War of Italian unification. The Austro-Prussian War was part of the wider rivalry between Austria and Prussia, and resulted in Prussian dominance over the German states.
In April 1867, the Austro-Hungarian Empire was established. Franz Josef, the head of the ancient Habsburg dynasty, was recognized as both Emperor of Austria and King of Hungary. Nevertheless, the issue of what form the Hungarian military would take remained a matter of serious contention between Hungarian patriots and Austrian leaders. As the impasse threatened the political union, Emperor Franz Josef ordered a council of generals in November of the same year. Ultimately, the leaders resolved on the following solution: in addition to the joint (k.u.k.) army, Hungary would have its own defence force, whose members would swear their oath to the King of Hungary (who was also Emperor of Austria) and the national constitution, use the Hungarian language of command, and display their own flags and insignia. (Austria would also form its own parallel national defence force, the "Landwehr".) As a result of these negotiations, on 5 December 1868, the Royal Hungarian Landwehr ("Magyar Kiralyi Honvédség", or Defence Force) was established.
The political alliances in Split shifted over time. At first, the Unionists and Autonomists were allied against the centralism of Vienna. After a while, when the national question came to prominence, they separated. Under Austria, however, Split can generally be said to have stagnated. The great upheavals in Europe in 1848 gained no ground in Split, and the city did not rebel.
Allied-occupied Austria was split into four occupation zones. The Soviet Union controlled the provinces of Lower Austria, Burgenland and eastern districts of Upper Austria, but the city of Vienna, which lies within Lower Austria, was occupied by all four allies. Austrian heavy industry (or what was left of it) concentrated around Linz, in the American zone, and in British-occupied Styria. Their products were in high demand in post-war Europe. Quite naturally, the administrators of the Marshall Plan channelled available financial aid into heavy industry controlled by the American and British forces. Industry quickly recovered, from 74.7% of pre-war output in 1948 to 150.7% in 1951. American planners deliberately neglected consumer goods industries, construction trades and small business. Their workers, almost half of Austrian industrial workforce, suffered from rising unemployment.
The political system of the Second Republic came to be characterized by the system of "Proporz", meaning that posts of some political importance were split evenly between members of the SPÖ and ÖVP. Interest group representations with mandatory membership (e.g., for workers, businesspeople, farmers etc.) grew to considerable importance and were usually consulted in the legislative process, so that hardly any legislation was passed that did not reflect widespread consensus. The Proporz and consensus systems largely held even during the years between 1966 and 1983, when there were non-coalition governments.
When in 1365 Albert's son Duke Rudolf IV of Austria suddenly died at the age of 26, Emperor Charles IV enfeoffed his younger brothers Albert III with the Pigtail and Leopold III the Just, who however began to quarrell about the Habsburg heritage. By the 1379 Treaty of Neuberg they finally split late Rudolf's territories: The elder Albertinian line would rule in the Archduchy of Austria proper (then sometimes referred to as "Lower Austria" ("Niederösterreich"), but comprising modern Lower Austria and most of Upper Austria), while the younger Leopoldian line ruled the Styrian, Carinthian and Carniolan duchies, then subsumed under the denotation of "Inner Austria". At that time their share also comprised Tyrol and the original Habsburg possessions in Swabia, called Further Austria; both collectively referred to as "Upper Austria" ("Oberösterreich") in that context, also not to be confused with the modern state of that name.
