Coronation and domestic strife s (12th and 13th centuries); the panels are now set into

Strasbourg Cathedral When Otto the Great died, the smooth succession to the imperial throne of Otto II had long been guaranteed. Otto II had been king of Germany for twelve years and emperor for five at the time of Otto the Great's death. Unlike his father, Otto II did not have any brothers to contest his claims to the throne. On May 8, the nobles of the Empire assembled before Otto II and, according to the Saxon Chronicler
Widukind of Corvey, "elected" Otto II as his father's successor. One of Otto II's first acts was to confirm the rights and possessions of the
archbishop of Magdeburg. Although Otto II had succeeded peacefully to the throne, internal divisions of power still remained unaddressed. During his first seven years as emperor, he was constantly occupied with maintaining Imperial power against internal rivals and external enemies. The domestic problems Otto the Great faced between 963 and 972 had not been resolved by his death. The Saxon nobility continued to resist the
Archdiocese of Magdeburg located along the Empire's eastern border. Though established by Otto I, the exact details of the diocese's boundaries were left to Otto II and his aides. Otto II's marriage Theophanu proved to be to his disadvantage because the Saxon nobles felt it distanced the emperor from their interests. Among Otto II's chief advisors, only the Saxon Bishop
Dietrich I of Metz had close connections with the old Saxon nobility. His other advisers lacked support from the Empire's various dukes. The
archbishop of Mainz,
Willigis, appointed in 975, who had been Otto II's advisor since Otto the Great's second expedition into Italy in the 960s, had not been born into a noble family.
Hildebald of Worms, who had been appointed as Otto II's
chancellor in 977 and then as
bishop of Worms in 979, was also not from a noble family. Otto the Great also failed to clarify affairs in Italy prior to his death. Otto died soon after the appointment of
Pope Benedict VI in 973. In 974 Benedict was imprisoned in the
Castel Sant'Angelo, the stronghold of the
Crescentii family. When Otto II sent an imperial representative, Count Sicco, to secure his release,
Crescentius I and Cardinal-Deacon Franco Ferrucci, who would subsequently become
Boniface VII, an
antipope, had Benedict murdered while still in prison. Following his coronation, a rift developed between Otto II and his mother, Empress Adelaide. From the death of Otto the Great until Easter 974, the dowager empress accompanied the emperor at all times, traveling throughout the Empire with him. However, Adelaide and Theophanu each mistrusted the influence the other held over Otto, causing friction within the household. A final meeting between Otto II and Adelaide was arranged shortly before
Pentecost in 978, but a peaceful outcome was not achieved, forcing Adelaide to retire to
Burgundy and to the protection of her brother King
Conrad of Burgundy.
Conflict with Henry II Otto II sought continued peace between himself and the descendants of his uncle
Henry I, Duke of Bavaria. To ensure domestic tranquillity, Otto II, on 27 June 973, granted control over the imperial castles in
Bamberg and
Stegaurach to his cousin Duke
Henry II of Bavaria. This was not enough for the young Bavarian duke, who wished to extend his influence in the
Duchy of Swabia as his father had under Otto the Great. The death of Bishop
Ulrich of Augsburg on 4 July, brought the conflict between the cousins to a head. Without consulting Otto, Henry named his cousin
Henry as the new bishop of Augsburg. Augsburg was located on the western side of the Swabian-Bavarian border, the territory of Henry's brother-in-law Duke
Burchard III of Swabia. Henry's actions in naming a bishop in a duchy not his own and without Imperial direction brought him into conflict with both Otto and Burchard. Not desiring civil war, Otto, on 22 September 973,
invested Henry as bishop. On 12 November 973, Burchard died with no heir: his union to
Hedwig, sister of Henry, had produced no children. With no clear successor, Henry demanded that Otto name him as the new
duke of Swabia. The emperor sensed the far-reaching ambitions of his cousin and denied his request. Instead, Otto named as duke his nephew
Otto, son of his half-brother, Liudolf, who had once been duke of Swabia. Prior to this appointment, Otto had been a long-time opponent of Henry's expanding influence in Swabia. By naming the son of his half-brother instead of his cousin, Otto reinforced his father's policy of appointing close family members to key posts throughout the Empire. This appointment elevated the descendants of Otto the Great above other kin in the selection process, further dividing Otto II and Henry II. The appointment of the young Otto as duke of Swabia was taken by Henry as an assault on his claim to the Imperial throne and a slight to his honor. He and his advisor, Bishop
Abraham of Freising, conspired with the
duke of Poland,
Mieszko I, and the
duke of Bohemia,
Boleslaus II, against Otto II in 974. While the historical sources do not describe the goals of the conspirators, Henry II likely intended to restore his honor and to ensure his position as the second most influential man in the Empire. Upon hearing of the conspiracy, Poppo, the
bishop of Würzburg, demanded that Henry and his followers submit to Otto II or face
excommunication. Otto the Great's efforts to consolidate the Church under Imperial control had made this type of action normal. Henry and his followers complied and submitted to Otto II before armed conflict broke out. Otto II, however, severely punished the conspirators: Henry was imprisoned at
Ingelheim and Bishop Abraham at
Corvey. By 976, Henry had returned to Bavaria. Whether Otto released him from prison or he escaped is not known for certain. Upon his return, Henry openly rebelled against Otto, claiming rulership over the Empire for himself. Henry mobilized the Saxon nobility against Otto. In particular, Henry had strong connections to Margrave
Gunther of Merseburg, Count
Egbert the One-Eyed, and
Dietrich I of Wettin, who were all displeased with Otto's lack of adherence to Saxon tradition. In response to the rebellion, Otto stripped Henry of his duchy and had him excommunicated. Otto then marched his army south to Bavaria and laid siege to
Regensburg, Henry's stronghold. Otto's army eventually broke through the city's defenses, forcing Henry to flee to Bohemia. With Henry deposed, in July 976 Otto issued far-reaching edicts on the reorganization of the southern German duchies. He reduced the size of
Duchy of Bavaria by almost a third. From the excised Bavarian territory, Otto established the
Duchy of Carinthia in southern Germany. By depriving Bavaria of the
March of Verona, Otto considerably reduced the influence of the Bavarian dukes in northern Italy and in general Imperial policy regarding Italy. Otto gave the diminished Duchy of Bavaria to his nephew Otto, the duke of Swabia, and appointed
Henry III, son of the former Bavarian Duke
Berthold, as duke of Carinthia. These appointments continued his policy of appointing individuals who had no political links to Otto the Great, including those who had even rebelled against him. With matters in southern Germany settled, Otto II turned his attention to defeating and capturing Henry. After a failed first invasion into Bohemia, Otto marched to Bohemia a second time in August 977. While in Bohemia,
a revolt broke out in Bavaria. The bishop of Augsburg and the newly appointed Carinthian duke joined Henry in rebellion, forcing Otto to return from Bohemia. The emperor, aided by the duke of Swabia and Bavaria, met the rebels at
Passau and, after a long siege, forced them into submission. Otto then brought the rebels before the
Imperial Diet in
Quedlinburg on March 31, 978. Boleslaus was treated with honors and swore loyalty to Otto. Mieszko recognized Otto's royal authority. Otto imprisoned Henry under the custody of the
bishop of Utrecht where he remained until Otto's death in 983. While Otto the Great had pardoned rebellious family members for their crimes, Otto followed a different policy. Instead, Otto hoped to subordinate the Bavarian line of Ottonians to his authority. Henry's four-year-old son, also named
Henry, was sent to
Hildesheim to study for an ecclesiastical career. It appears Otto intended to end the Bavarian Ottonians' secular control of Bavaria. Under a new duke, Bavaria remained a remote area of the Empire. Otto only visited the duchy three times during his reign, in all cases accompanied by the military.
War with Denmark In 950, Otto the Great had subdued the
Kingdom of Denmark and forced the Danish King
Gorm the Old to accept him as his overlord. Otto the Great also forced the king and his heir apparent
Harald Bluetooth to
convert to Christianity. Under the reign of Otto the Great, Denmark fulfilled all its obligations and regularly paid tribute to the Germans. When Harald became king in 958, he expanded the control of his kingdom into
Norway, becoming king there in 970. With his newly obtained power, the young ruler was no longer willing to accept German supremacy over his kingdom. In summer 974, Harald rebelled against Otto II. With peace concluded, Otto II returned to Aachen to celebrate
Pentecost, and then moved towards
Nijmegen. During the journey, in late June or early July 980, the Empress Theophanu gave birth to the Imperial couple's only son:
Otto III. ==Reign in Italy==
