In
Austrian history, the 'First Republic' refers to the period after
World War I, following the breakup of the
Austro-Hungarian Monarchy, up to
World War II. Austria was de-facto republic, as the constitution did not identify it directly as a republic, its official name was the Federal State of Austria. This period was marked by violent strife between the left and the right, as seen in the
July Revolt of 1927. The
Constitution of Austria was enacted in
1920 and amended in
1929. The First Republic ends with the
Anschluss to
Nazi Germany in
1938, or, according to some accounts with the establishment of the
Austro-fascist dictatorship in
1933/
34 following the
Austrian Civil War. (The constitution of the Austro-fascist state did not consider Austria a
republic, but only a ''Bundesstaat'', i.e. a
federal state).
Foundation
In 1919, the state of
German Austria was dissolved by the
Treaty of Saint Germain, which ceded German-populated regions in
Sudetenland to
Czechoslovakia, German-populated
Tyrol to
Italy and a portion of southern land to the
Kingdom of Serbs, Croats and Slovenes (later renamed Yugoslavia). The treaty angered the German population in Austria who claimed that it violated the
Fourteen Points laid out by United States President
Woodrow Wilson during peace talks, specifically the right to "self-determination" of all nations. The new state managed to prevent two land claims from being taken by their neighbours. The first was the south-eastern part of
Carinthia, which was inhabited mostly by Slovenians. It was prevented from being taken by the new SHS-state through a
plebiscite on
October 20,
1920, in which the population chose to remain with Austria. The second land-claim that was prevented was
Hungary's claim to
Burgenland, which, under the name "Western Hungary", had been part of the Hungarian kingdom since 1647. It was inhabited mostly by a German-speaking population, but had also Croat- and Hungarian-speaking minorities. Through the Treaty of St. Germain it became part of the Austrian Republic in
1921. After a plebiscite which was disputed by Austria, the city of
Sopron (German Ödenburg) remained in Hungary.
After the war, Austria was governed by a coalition of left-wing and right-wing parties which had established a number of progressive socioeconomic and labour legislation. In
1920, the coalition government established the
Constitution of Austria. However the new state was difficult to control, as much of the former empire's important economic regions had been taken away with the foundation of new nation-states. The matter was further complicated by the fact that a number of these new nation-states were still dependent on Vienna's banks.
Government and Politics, 1920–1932
After 1920, Austria's government was dominated by the
Christian Social Party which retained close ties to the
Roman Catholic Church. The party's first Chancellor,
Ignaz Seipel, attempted to forge a political alliance between wealthy industrialists and the Roman Catholic Church. Despite the nation having a steady political party in power, the politics of the nation were fractious and violent, with both left-wing and right-wing political bodies forming
paramilitary forces which clashed with each other. In 1927, left-wing supporters engaged in a massive protest over the acquittal of right-wing paramilitaries who were found guilty of killing a man and a child. The huge protest was known as the
July Revolt of 1927. The July Revolt was put down through violence by police which killed a number of protestors. The violence in Austria continued to escalate until the early 1930s when
Engelbert Dollfuß became Chancellor.
Austrofascism

Engelbert Dollfuss.
Chancellor Engelbert Dollfuß () of the Christian Social Party took power in Austria in 1932, and moved the party and Austria towards dictatorship, centralization and
fascism. In 1933, Dollfuß took advantage of an error in a bill in parliament, and his cabinet voted to dissolve the
National Council and declared that parliament ceased to function.
The government was in competition with the growing
Austrian Nazi party, which wanted Austria to join Germany. Dollfuß's
Austrofascism tied Austria's roots with
Roman Catholicism to the government, as a means to show reason to why Austria should not join a predominantly
Protestant Germany. Violence escalated into civil war between Nazis, socialists, and Austrofascists.
In 1934, Dollfuß created a
one-party state, to be led by the
Fatherland Front. The state took complete control on employer–employee relations, and began to crackdown on pro-Nazi and pro–German-unification sympathizers. The Nazis responded by assasinating Engelbert Dollfuss on
July 25,
1934.
This assassination by the Austrian Nazis infuriated Austria's neighbour,
Fascist Italy under dictator
Benito Mussolini, who suspected German involvement and promised the Austrofascist regime military support if Germany where to invade, as the Nazis had claims on Italian-administered Tyrol. Italy's support helped save Austria from potential annexation in 1934.

The successor to Dollfuß,
Kurt Schuschnigg, maintained the ban on Nazi activities, but also banned Austria's national paramilitary force, the
Heimwehr in 1936.
''Anchluss''
In 1938, Hitler had gained Italy's favour on the issue of annexation of Austria, and made clear his immediate intentions to take over the country. Schuschnigg desperately tried to avoid war with Germany, and organized a
plebiscite set for
March 13 to decide whether Austria would join Germany or remain independent. Schuschnigg intended to rig the vote to insure a pro-Austrian victory. Hitler responded by demanding Schuschnigg's immediate resignation, which he was pressured to accept on
March 11 which the immediate threat of occupation. Schuschnigg was replaced by Austrian Nazi leader
Arthur Seyß-Inquart and Germany sent in troops the next day on
March 12, which took over the nation. On
March 13, the First Austrian Republic was formally dissolved and became part of Germany as part of
Anchluss (political union).
