After the disintegration of
Samo's realm, Alpine Slavs established the Principality of
Carantania in the
Eastern Alps, which was independent from around 660 to around 745, when it fell under the Bavarian zone of influence and was later incorporated in the
Frankish Empire. The formation of the principality and a period of peace made possible the emergence in the 8th century of so-called Carantanian culture. Until around 820, it was ruled as a semi-independent tribal polity. After the anti-Frankish rebellion of
Ljudevit Posavski, which was partially supported by Carantanians, the Carantanian principality was transformed into a Frankish
march, and later emerged as the feudal
Duchy of Carinthia. In the 10th century the Carantanians were significantly influenced by the
Bijelo Brdo culture of the
Pannonian Slavs. Carantanians were the first
Slavic people to accept
Christianity from the West. They were mostly Christianized by
Irish missionaries sent by the
Archdiocese of Salzburg, among them
Modestus, known as the "Apostle of Carantanians". This process was later described in the memorandum known as the
Conversio Bagoariorum et Carantanorum, which is thought to have over-emphasized the role of the Church of Salzburg in the Christianization process over similar efforts of the
Patriarchate of Aquileia. Several rebellions of the Carantanians against the Christianisations occurred in the late 8th century, which later served as the source of inspiration of the Slovenian Romantic poet
France Prešeren in his
epic-
lyric poem
The Baptism on the Savica. They were also mentioned in
Primary Chronicle from the 12th century, which alongside other historical sources and archaeological culture, indicates there were perceived as a well-formed Slavic ethnic group. However, with the loss of their independence, their name by the end of the 9th century lost ethnic meaning in favor of the territorial community. Part of them became
Germanized and
Romanized, while the remaining descendants who preserved their Slavic identity and language are known today as
Slovenes. == Language ==
