Austria played a central role in European History from the late 18th to the early 20th century. It initially emerged as a margraviate around 976 and developed into a duchy and later archduchy. In the 16th century, Austria started serving as the heart of the Habsburg Monarchy and the junior branch of the House of Habsburg – one of the most influential royal houses in history. As archduchy, it was a major component and administrative centre of the Holy Roman Empire. Following the Holy Roman Empire’s dissolution, Austria founded its own empire in the 19th century, which became a great power and the leading force of the German Confederation. Subsequent to the Austro-Prussian War and the establishment of a union with Hungary, the Austro-Hungarian Empire was created. Austria was involved in both world wars; it started the first one under Emperor Franz Joseph and was the birthplace of Adolf Hitler, who provoked the second one.
Austria is a parliamentary representative democracy with a President as head of state and a Chancellor as head of government. Major urban areas of Austria include Graz, Linz, Salzburg and Innsbruck. Austria is consistently ranked as one of the richest countries in the world by per capita GDP terms. The country has developed a high standard of living and in 2018 was ranked 20th in the world for its Human Development Index. The republic declared its perpetual neutrality in foreign political affairs in 1955. Austria has been a member of the United Nations since 1955 and joined the European Union in 1995. It harbours the OSCE and OPEC and is a founding member of the OECD and Interpol. Austria also signed the Schengen Agreement in 1995, and adopted the euro currency in 1999.
