 The Unruoching margrave Berengar of Friuli even succeeded Charles the Fat as King of Italy in 888.After the German king Otto I had campaigned northern Italy under Berengar's grandson King Berengar II, in 952 he merged Friuli into the vast March of Verona, which he granted it to his brother Duke Henry I of Bavaria, who already controlled the adjacent Carinthian and Carniolan marches.After the deposition of Henry's son and successor Duke Henry the Wrangler in 976, Emperor Otto II separated Carinthia from the Bavaria as a duchy in its own right, ruled by Duke Henry the Younger who was also given suzerainty over the southeastern Bavarian marches, including Verona, Istria, Carniola and Styria.
