Windic March

[2] Samo's tribal union included the Windic March (Marca Vinedorum) of Duke Valuk (Wallucus Dux), located in the Eastern Alps,[3] in 631.

Backed by the Archbishop of Salzburg, they conquered the territory around Metlika up to the Kolpa River in the southeast, the later White Carniola (Bela krajina) region.

Through a marriage to the last heiress Sophia of Weichselburg, the Counts of Andechs, then at the peak of their power as Margraves of Istria and Dukes of Merania came to dominate the territory.

Frederick II thereafter called himself a dominus Carniole (Lord of Carniola) and succeeded his father as Duke of Austria and Styria in the following year.

After 1282, despite King Rudolf I's grant to his sons, Carniola and the Windic march were united under the control of the Meinhardiner duke Meinhard of Carinthia.
