Otto I Holy Roman Emperor - Campaigns in Italy and eastern Europe

Meanwhile, Italy had fallen into political chaos. On the death (950), possibly by poisoning, of Lothair of Arles, the Italian throne was inherited by a woman, Adelaide of Italy, the respective daughter, daughter-in-law, and widow of the last three kings of Italy. A local noble, Berengar of Ivrea, declared himself king of Italy, abducted Adelaide, and tried to legitimize his reign by forcing Adelaide to marry his son Adalbert. However, Adelaide escaped to Canossa and requested German intervention. Luitdolf and Henry independently invaded northern Italy to take advantage of the situation, but in 951 Otto frustrated his son's and his brother's ambitions by invading Italy himself, forcing Berengar to swear fealty, and then, having been widowed since 946, marrying Adelaide.

This marriage triggered another revolt. When Adelaide bore a son, Luitdolf feared for his position as Otto's heir, and in 953 he rebelled in league with Conrad the Red and the Archbishop of Mainz. While Otto was initially successful in reasserting his authority in Lorraine, he was captured while attacking Mainz, and by the next year, the rebellion had spread throughout the kingdom. However, Conrad and Luitdolf erred by allying themselves with the Magyars. Extensive Magyar raids in southern Germany in 954 compelled the German nobles to reunite, and at the Diet of Auerstadt, Conrad and Luitdolf were stripped of their titles and Otto's authority reestablished. In 955, Otto cemented his authority by routing Magyar forces at the Battle of Lechfeld.
