Otto I (1117 – 11 July 1183), called the Redhead (German: der Rotkopf), was Duke of Bavaria from 1180 until his death. He was the first Bavarian ruler from the House of Wittelsbach, a dynasty which reigned until the abdication of King Ludwig III of Bavaria in the German Revolution of 1918.
Upon the death of his father in 1156, Otto inherited the possessions of the Wittelsbach line of the family, and also succeeded his father as Count Palatine of the Bavarian duchy, then under the rule of Henry the Lion, a scion of the Welf dynasty.[1]
Otto was a close ally of the Holy Roman EmperorFrederick Barbarossa, and was militarily and diplomatically active in the service of the Emperor. In 1155, as one of the best knights in the employ of the Emperor, he stormed and conquered the position overlooking and dominating the Defile of Ceraino near Verona with 200 selected soldiers, thus enabling the safe march of Barbarossa's army caravan across the Alps back to Germany after the Emperor's coronation at Rome. In the Dominium mundi conflict between emperor and pope culminating at the 1157 Reichstag of Besançon, fiery Otto could only be kept from smiting the papal legate Cardinal Rolando Bandinelli with his battleaxe by the personal intervention of Frederick.
He was finally rewarded with the duchy of Bavaria on 16 September 1180 at Altenburg in Thuringia, after the deposition of Duke Henry the Lion. But he was so little regarded by many of the Bavarian aristocracy that they are said to have refused him the customary homage.[3] They went so far as to refuse to attend his first court assembly at Regensburg.[4]
With the separation of Styria under Duke Ottokar IV in the same year, Bavaria lost the last of her southeastern territories. With the support of the emperor and his brother Conrad, Otto was able to secure the rule of his dynasty from the wary Bavarian nobility. His descendants ruled Bavaria for the next 738 years.
In 1182 or 1183, Duke Otto bought Dachau castle, the ministeriales, and all other appurtenances for a large sum of cash from the widow of the last duke of Dachau and Merania, Conrad II, Duke of Merania.[5]
