Austrians 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.

The Archduchy of Austria was a major principality of the Holy Roman Empire and the nucleus of the Habsburg monarchy. With its capital at Vienna, the archduchy was centered at the Empire's southeastern periphery.
