The Marca Veronensis et Aquileiensis was created by King Berengar I of Italy about 890 as part of a general restructuring of his realm, when it replaced the former Carolingian March of Friuli last held by Berengar's liensman Walfred.
After several revolts led by his Bavarian cousins, Emperor Otto II in 976 deposed Duke Henry II of Bavaria and established the Duchy of Carinthia under the loyal Luitpolding liensman Henry the Younger on the southeastern territories.
