Austria, formally the Republic of Austria, is a nation in Central Europe's southernmost region. It is a federation of nine states, one of which is the capital Vienna, the most populous city and state. The nation is bounded to the northwest by Germany, to the north by the Czech Republic, to the northeast by Slovakia, to the east by Hungary, to the south by Slovenia and Italy, and to the west by Switzerland and Liechtenstein. It has a population of 9 million people and a landlocked area of 83,879 km2 (32,386 sq mi).
At the end of the first millennium, Austria arose from the ruins of the Eastern and Hungarian March. Originally a Bavarian margraviate, it became a duchy of the Holy Roman Empire in 1156, and then an archduchy in 1453. Vienna started functioning as the administrative imperial seat in the 16th century, and Austria, therefore, became the stronghold of the House of Habsburg. Following the breakup of the Empire in 1806, Austria founded its own empire, which grew to become a major power and the dominating member of the German Confederation. The loss of the Austrian Empire in the Austro-Prussian War of 1866 ended the Confederation and cleared the ground for the foundation of Austria-Hungary a year later.
Following Archduke Franz Ferdinand's murder in 1914, Emperor Franz Joseph declared war on Serbia, beginning World War I. Following the Empire's defeat and subsequent collapse, the Republic of German-Austria was established in 1918, followed by the First Austrian Republic in 1919. Anti-parliamentary attitudes resulted in the creation of an Austrofascist dictatorship under Engelbert Dollfuss in 1934 during the interwar era. Adolf Hitler incorporated Austria into Nazi Germany a year before World War II began, and it became a sub-national entity. Following its liberation in 1945 and a lengthy period of Allied occupation, the nation regained sovereignty in 1955 and proclaimed everlasting neutrality.
Austria is a parliamentary representative democracy with a president who is chosen by the people and a chancellor who is the head of government and chief executive. Vienna, Graz, Linz, Salzburg, and Innsbruck are among the major cities. Austria is routinely recognized as one of the world's wealthiest nations by GDP per capita, as well as one of the countries with the greatest quality of life, and was placed 18th in the world for its Human Development Index in 2020.
Austria has been a UN member since 1955 and a member of the European Union since 1995. It is a founding member of the OECD and Interpol, as well as the OSCE and OPEC. In addition, it ratified the Schengen Agreement in 1995 and embraced the euro in 1999.
