An estimated 13,000 to 40,000 Slovenes in the Austrian state of Carinthia (the Carinthian Slovenes) as well as Croats (around 30,000) and Hungarians in Burgenland were recognised as a minority and have had special rights following the Austrian State Treaty () of 1955. The Slovenes in the Austrian state of Styria (estimated at a number between 1,600 and 5,000) are not recognised as a minority and do not have special rights, although the State Treaty of 27 July 1955 states otherwise.
