Arnulf II (birth unknown; died 14 July 937), also known as the Bad (), the Evil (der Böse) or the Wicked, a member of the Luitpolding dynasty, held the title of Duke of Bavaria from about 907 until his death in 937. He is numbered in succession to Arnulf of Carinthia, counted as Arnulf I. Life The year of Arnulf's birth is unknown, but it is said that he was the namesake of other Arnulfs born around the time of the reign of the seventh-century bishop Arnulf of Metz and the Carolingian king Arnulf of Carinthia. Arnulf was the son of Margrave Luitpold of Bavaria and Cunigunde, herself a member of the Ahalolfing dynasty, daughter of Berthold I, the count palatine of Swabia. Her brother Erchanger assumed the Swabian ducal title in 915. Under the weak rule of the East Frankish king Louis the Child, Margrave Luitpold had already achieved a strong position in the Bavarian lands, succeeding the Wilhelminer margraves. He ruled over extended estates along the Danube with Regensburg (Ratisbon), and in the adjacent Nordgau. Duke of Bavaria Together with numerous Bavarian nobles, Arnulf's father was killed in the 907 Battle of Pressburg (Bratislava), when the Bavarian Heerbann under his command suffered a crushing defeat in a campaign against the Hungarian forces of Grand Prince Árpád. After the death of his father, Arnulf succeeded him in his Bavarian lands, and soon after he assumed the title of a "Duke of Bavaria" as ruler of the estates around Regensburg. An energetic and combative man, he received broad support from the local nobles, however, already during his ascension in to dukedom, he was faced with constant raids from the Hungarians. These attacks had laid waste the East Frankish lands of Bavaria, Saxony, and Thuringia. Besieged by frequent Hungarian raids and desperate to raise funds to finance a re-organized defense, Arnulf strengthened his power through confiscation of church lands and the secularization of numerous monastery estates, which earned him the nickname "the Bad" by medieval chroniclers. In several skirmishes he was able to force back the Hungarian invaders and he defeated a small force in 913 with the support by his Swabian relatives. Having re-established the stem duchy of Bavaria, he eventually negotiated a truce with the Hungarian princes, who thereafter largely passed through Bavaria on their raids into other German duchies. Imperial politics Duke Arnulf pursued a policy of independence
