The proto-Slovene language was spoken in a much larger territory than modern Slovenia, which included most of the present-day Austrian states of Carinthia and Styria, as well as East Tyrol, the Val Pusteria in South Tyrol, and some parts of Upper and Lower Austria. By the 15th century most of these areas had been gradually Germanised. The northern border of Slovene-speaking territory stabilised on a line from north of Klagenfurt to south of Villach and east of Hermagor in Carinthia, while in Styria it closely followed the current Austrian-Slovenian border.
