First Austrian Republic in the context of "Hungarian Republic (1919–20)"

The Federal State of Austria (Austrian German: Bundesstaat Österreich; colloquially known as the "Ständestaat") was a continuation of the First Austrian Republic between 1934 and 1938 when it was a one-party state led by the conservative, nationalist, corporatist, clerical fascist and Catholic Fatherland Front. The Ständestaat concept, derived from the notion of Stände ("estates" or "corporations"), was advocated by leading regime politicians such as Engelbert Dollfuss and Kurt Schuschnigg. The result was a authoritarian government based on a mix of Italian Fascist and conservative Catholic influences.

It ended in March 1938 with the Anschluss, the German annexation of Austria. Austria would not become an independent country again until 1955, when the Austrian State Treaty ended the Allied occupation of Austria.

Austrians (German: Österreicher) are the citizens and nationals of Austria. The English term Austrians was applied to the population of Habsburg Austria from the 17th or 18th century. Subsequently, during the 19th century, it referred to the citizens of the Empire of Austria (1804–1867), and from 1867 until 1918 to the citizens of Cisleithania. In the closest sense, the term Austria originally referred to the historical March of Austria, corresponding roughly to the Vienna Basin in what is today Lower Austria.

Historically, Austrians were regarded as Germans and viewed themselves as such. The Austrian lands (including Bohemia) were part of the Holy Roman Empire and the German Confederation until the Austro-Prussian War in 1866 which resulted in Prussia expelling the Austrian Empire from the Confederation. Thus, when Germany was founded as a nation-state in 1871, Austria was not a part of it. In 1867, Austria was reformed into the Austro-Hungarian Empire. After the collapse of the Austro-Hungarian Empire in 1918 at the end of World War I, Austria was reduced to a rump state and adopted and briefly used the name the Republic of German-Austria (German: Republik Deutschösterreich) in an attempt for union with Germany, but was forbidden due to the Treaty of Saint-Germain-en-Laye (1919). The First Austrian Republic was founded in 1919. Nazi Germany annexed Austria with the Anschluss in 1938.

The Kingdom of Hungary, referred to retrospectively as the Regency, the Horthy era, the Horthy regime, and Horthyist Hungary, existed as a country from 1920 to 1946 under the rule of Miklós Horthy for the most of its existence, who officially represented the Hungarian monarchy after a period of revolutions and the counter-revolution as the Regent of Hungary. In reality there was no king, and attempts by King Charles IV to return to the throne shortly before his death were prevented by Horthy.

Horthy came to power after supressing the Hungarian Soviet Republic during the period of White Terror, installing an authoritarian political system relying on the traditional economic elites and bureaucracy. Hungary under Horthy was characterized by its conservative, nationalist, and fiercely anti-communist character; some historians have described this system as para-fascist. The government was based on an unstable alliance of conservatives and right-wingers; while conservatism was predominant in the 1920s, afterwards Horthy manoeuvered between conservatives and the radical right with fascist leanings. Foreign policy was characterized by revisionism — the total or partial revision of the Treaty of Trianon, which had seen Hungary lose over 70% of its historic territory along with over three million Hungarians, who mostly lived in the border territories outside the new borders of the kingdom, in the Kingdom of Romania and the newly created states of Czechoslovakia and the Kingdom of Serbs, Croats and Slovenes (in greatly enlarged Romania there also remained a significant Hungarian population in Székely Land). Republican Austria, the successor of the former other half of the dual monarchy also received some minor territory from Hungary. Thus the post-1918 kingdom can be described as a rump state. Hungary's interwar politics were dominated by a focus on the territorial losses suffered from this treaty, with the resentment continuing until the present. After a period of international isolation in the 1920s, it began maintaining ties with Fascist Italy and Nazi Germany.

Following their defeat in World War I, the Central Powers agreed to pay war reparations to the Allied Powers. Each defeated power was required to make payments in either cash or kind. Because of the financial situation in Austria, Hungary, and Turkey after the war, few to no reparations were paid and the requirements for reparations were cancelled. Bulgaria, having paid only a fraction of what was required, saw its reparation figure reduced and then cancelled. Historians have recognized the German requirement to pay reparations as the "chief battleground of the post-war era" and "the focus of the power struggle between France and Germany over whether the Versailles Treaty was to be enforced or revised."

The Treaty of Versailles (signed in 1919) and the 1921 London Schedule of Payments required the Central Powers to pay 132 billion gold marks (US$33 billion at the time which is $605 billion in 2025) in reparations to cover civilian damage caused during the war. This figure was divided into three categories of bonds: A, B, and C. Of these, Germany was required to pay towards 'A' and 'B' bonds totaling 50 billion marks (US$12.5 billion) unconditionally. The payment of the remaining 'C' bonds was interest-free and without any specific schedule for payment, instead being contingent on the Weimar Republic's eventual ability to pay, as was to be assessed at some future point by an Allied committee.

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 Scientific-Humanitarian Committee (German: Wissenschaftlich-humanitäres Komitee, WhK) was a transnational advocacy group and civil rights organization founded by Magnus Hirschfeld in Berlin in May 1897, to campaign for the legal rights and social recognition of lesbian, gay, bisexual, and transgender (LGBT) people, and against their institutionalized discrimination and persecution in Western societies. It was the first LGBT rights organization in history. The motto of the organization was Per scientiam ad justitiam ("Through science to justice"), and the committee included representatives from various professions. The committee's membership peaked at about 700 people. In 1929, Kurt Hiller took over as chairman of the group from Hirschfeld. At its peak, the WhK had branches in approximately 25 cities in Weimar Germany, the Republic of Austria, and the Netherlands.

Weimar culture was the emergence of the arts and sciences that happened in Germany during the Weimar Republic, the latter during that part of the interwar period between Germany's defeat in World War I in 1918 and Hitler's rise to power in 1933. 1920s Berlin was at the hectic center of the Weimar culture. Although not part of the Weimar Republic, German-speaking Austria, and particularly Vienna, is also sometimes included as part of Weimar culture.

Germany, and Berlin in particular, was fertile ground for intellectuals, artists, and innovators from many fields during the Weimar Republic years. The social environment was chaotic, and politics were passionate. German university faculties became universally open to Jewish scholars in 1918. Leading Jewish intellectuals on university faculties included physicist Albert Einstein; sociologists Karl Mannheim, Erich Fromm, Theodor Adorno, Max Horkheimer, and Herbert Marcuse; philosophers Ernst Cassirer and Edmund Husserl; political theorists Arthur Rosenberg and Gustav Meyer; and many others. Nine German citizens were awarded Nobel Prizes during the Weimar Republic, five of whom were Jewish scientists, including two in medicine. Jewish intellectuals and creative professionals were among the prominent figures in many areas of Weimar culture.
