Not exactly.

The Slovenes are a Slavic-speaking ethnic group living primarily on the eastern region of the Dolomite Alps, historically known as the 'Julian Alps'.

Slavic-speakers probably began entering the region in the 7th century, but for almost 100 years did not likely impact the local culture. By the 9th century, however, the Julian Alpine people had become thoroughly Slavic.

The identity of these early Alpine Slavs is largely unknown, but by the 11th century had become culturally reoriented from western-Slavic linguistically and culturally, towards south-Slavic. By the 13th century these areas had become part of the Holy Roman Empire.

After being Germanized to a great degree, by the end of the 30 years' war, Slovene culture had fully reemerged as a distinct south-Slavic Alpine culture and language.
