Otto II spent his reign continuing his father's policy of strengthening Imperial rule in Germany and extending the borders of the Empire deeper into Southern Italy.
Though Otto I preferred Anna Porphyrogenita, daughter of former Byzantine Emperor Romanos II, as she was born in the purple, her age (then only five years old) prevented serious consideration by the East.
[3] Otto II spent his reign continuing his father's policy of strengthening Imperial rule in Germany and extending it deeper into Italy.
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.
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.
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.
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.
[3] Years earlier in 958, Otto the Great banished their father Reginar III, Count of Hainaut, to Bohemia after he attempted a failed revolt.
Sickness among his troops brought on by winter and a French relief army under Hugh Capet forced Otto II and Charles to lift the siege on November 30, and to return to Germany.
[8] Despite neither side obtaining a clear victory, Otto II felt his honor was sufficiently restored and opened peace negotiations with the French King.
When Otto II sent an imperial representative, Count Sicco, to secure his release, Crescentius I and Cardinal Franco Ferrucci had Benedict VI murdered while still in prison in 974.
[13] Following the New Year, Otto II led his Imperial court to Rome, reaching the city on February 9, 981, where the Emperor restored Pope Benedict VII to his papal throne without difficulty.
Otto II proceeded to hold court in Rome, making the city his Imperial capital, where he received princes and nobles from all parts of western Europe.
Originally appointed by Otto I as Prince of Benevento and Capua in 961, Pandulf waged war against the Byzantines and expanded Ottonian control to include the Duchy of Spoleto in 967.
Upon hearing of Pandulf's death, Otto II, ruling from Rome, traveled south to install Thrasimund IV as Duke of Spoleto.
[9] Needing allies in his campaign against the Muslims and the Byzantine Empire, Otto II reconciled with Amalfian Duke Manso I, granting Imperial recognition of his rule over Salerno.
[18] Otto II's march caused the Byzantine Empire to seek an alliance with Muslim Sicily in order to hold on to its southern Italian possessions.
Unable to flee back to his stronghold in Sicily due to an Ottonian naval blockade, al-Qasim faced Otto's army in what has been come to be known as the Battle of Stilo south of Crotone at Cape Colonna on July 14, 982.
After a violent clash, a corps of Otto II's heavy cavalry destroyed the Muslim center and pushed towards al-Qasim's guards, with the Emir killed during the charge.
[20] Despite the Emir's death, the Muslim troops did not flee the battlefield but regrouped and managed to surround the Imperial soldiers, slaughtering many of them and inflicting a severe defeat upon the Emperor.
Landulf IV of Benevento and Pandulf II of Salerno, Bishop Henry I of Augsburg, Margrave Gunther of Merseburg, the Abbot of Fulda, and numerous other Imperial officials were among the battle's casualties.
[19] He sent his nephew Otto I, Duke of Swabia and Bavaria, back to Germany with news of the defeat and to call the German nobles to the assembly, but his emissary died en route on November 1, 982, in Lucca.
The defeat at Stilo cost the Empire many nobles, forcing Otto II to end Henry's banishment in order to stabilize domestic affairs in Germany while he campaigned against the Muslims and Byzantines in southern Italy.
Otto II then prepared for a new campaign against the Muslims[3] and obtained a settlement with the Republic of Venice, whose assistance he needed following the destruction of his army at Stilo.
It is possible that the conditions in southern Italy following the defeat required Otto II to act quickly in designating an Imperial heir to ensure the Empire's future.
"[22] In the Obotrite territories along the Elbe River, the Luticians initiated a revolt aimed at the abolition of feudal rule and Christianity,[21] drawing upon considerable support by the Obodrite populace and their leader Mstivoj.
[3] Otto II's money and possessions were divided among the Catholic Church, the poor of the Empire, his mother Adelaide and sister Matilda, and those nobles loyal to him.
The arrival of a minor on the Imperial throne threw the Empire into confusion, allowing Otto III's mother, the Byzantine Princess Theophanu, to reign as his regent.
[28] The threat of war from Willigis and Conrad of Swabia forced Henry to relinquish Otto III on June 29, 984 and to respect the regency of Empress Theophanu.
Despite having a child under the regency of his mother as a ruler, the structure established by Otto the Great remained strong as most of the Empire's most powerful officials stayed loyal to the Imperial system.
