Otto the Great
Otto I, known as Otto the Great or Otto of Saxony, was East Frankish king from 936 and Holy Roman Emperor from 962 until his death in 973. He was the eldest son of Henry the Fowler and Matilda of Ringelheim.
Otto inherited the Duchy of Saxony and the kingship of the Germans upon his father's death in 936. He continued his father's work of unifying all German tribes into a single kingdom and greatly expanded the king's powers at the expense of the aristocracy. Through strategic marriages and personal appointments, Otto installed members of his family in the kingdom's most important duchies. This reduced the various dukes, who had previously been co-equals with the king, to royal subjects under his authority. Otto transformed the church in Germany to strengthen royal authority and subjected its clergy to his personal control.
After putting down a brief civil war among the rebellious duchies, Otto defeated the Magyars at the Battle of Lechfeld in 955, thus ending the Hungarian invasions of Western Europe. The victory against the pagan Magyars earned Otto a reputation as a savior of Christendom and secured his hold over the kingdom. By 961, Otto had conquered the Kingdom of Italy. Following the example of Charlemagne's coronation as "Emperor of the Romans" in 800, Otto was crowned emperor in 962 by Pope John XII in Rome.
Otto's later years were marked by conflicts with the papacy and struggles to stabilize his rule over Italy. Reigning from Rome, Otto sought to improve relations with the Byzantine Empire, which opposed his claim to emperorship and his realm's further expansion to the south. To resolve this conflict, the Byzantine princess Theophanu married his son Otto II in April 972. Otto finally returned to Germany in August 972 and died at Memleben in May 973. Otto II succeeded him.
Otto has been consistently depicted in historiography through different eras as a successful ruler. He is also reputed to be a great military commander, especially on the strategic level – this also means that the empire this talent recreated was too vast for contemporary administrative structures and could only be governed as a confederacy. Modern historians, while not denying his strong character and his many fruitful initiatives, explore the emperor's capability as a consensus builder – a process that goes in parallel with greater recognition of the nature of consensus politics in medieval Europe as well as different roles played by other actors in his time.
Historian David Bachrach notes the role of the bureaucracy and administration apparatus which the Ottonians inherited from the Carolingians and ultimately from the Ancient Romans, and which they developed greatly themselves: "It was the success of the Ottonians in molding the raw materials bequeathed to them into a formidable military machine that made possible the establishment of Germany as the preeminent kingdom in Europe from the tenth through the mid-thirteenth century." Bachrach highlights in particular the achievements of the first two Ottonian rulers, Henry I and Otto the Great in creating this situation. Their rules also marked the start of new, vigorous literary traditions. The patronage of Otto and his immediate successors facilitated a so-called "Ottonian Renaissance" of arts and architecture. As one of the most notable Holy Roman emperors, Otto's footprint in artistic depictions is also considerable.
Early life
Birth and family
Otto was born on 23 November 912, the oldest son of the Duke of Saxony, Henry the Fowler and his second wife Matilda, the daughter of Dietrich of Ringelheim, a Saxon count in Westphalia. Henry had previously married Hatheburg of Merseburg, also a daughter of a Saxon count, in 906, but this marriage was annulled, probably in 909 after she had given birth to Henry's first son and Otto's half-brother Thankmar. Otto had four full siblings: Hedwig, Gerberga, Henry and Bruno.Rise of the Ottonians
On 23 December 918, Conrad I, King of East Francia and Duke of Franconia, died. According to The Deeds of the Saxons by the Saxon chronicler Widukind of Corvey, Conrad persuaded his younger brother Eberhard of Franconia, the presumptive heir, to offer the crown of East Francia to Otto's father Henry. Although Conrad and Henry had been at odds with one another since 912, Henry had not openly opposed the king since 915. Furthermore, Conrad's repeated battles with German dukes, most recently with Arnulf, Duke of Bavaria, and Burchard II, Duke of Swabia, had weakened the position and resources of the Conradines. After several months of hesitation, Eberhard and the other Frankish and Saxon nobles elected Henry as king at the Imperial Diet of Fritzlar in May 919. For the first time, a Saxon instead of a Frank reigned over the kingdom.Burchard II of Swabia soon swore fealty to the new king, but Arnulf of Bavaria did not recognize Henry's position. According to the Annales iuvavenses, Arnulf was elected king by the Bavarians in opposition to Henry, but his "reign" was short-lived; Henry defeated him in two campaigns. In 921, Henry besieged Arnulf's residence at Ratisbon and forced him into submission. Arnulf had to accept Henry's sovereignty; Bavaria retained some autonomy and the right to invest bishops in the Bavarian church.
Heir apparent
Otto first gained experience as a military commander when the German kingdom fought against Wendish tribes on its eastern border. While campaigning against the Wends/West Slavs in 929, Otto's illegitimate son William, the future Archbishop of Mainz, was born to a captive Wendish noblewoman. With Henry's dominion over the entire kingdom secured by 929, the king probably began to prepare his succession over the kingdom. No written evidence for his arrangements is extant, but during this time Otto is first called king in the confraternity book of the Abbey of Reichenau.While Henry consolidated power within Germany, he also prepared for an alliance with Anglo-Saxon England by finding a bride for Otto. Association with another royal house would give Henry additional legitimacy and strengthen the bonds between the two Saxon kingdoms. To seal the alliance, King Æthelstan of England sent Henry two of his half-sisters, so he could choose the one which best pleased him. Henry selected Eadgyth as Otto's bride and the two were married in 930.
Several years later, shortly before Henry's death, an Imperial Diet at Erfurt formally ratified the king's succession arrangements. Some of his estates and treasures were to be distributed among Thankmar, Henry, and Bruno. But departing from customary Carolingian inheritance, the king designated Otto as the sole heir apparent without a prior formal election by the various dukes.
Reign as king
Coronation
Henry died from the effects of a cerebral stroke on 2 July 936 at his palace, the Kaiserpfalz in Memleben, and was buried at Quedlinburg Abbey. At the time of his death, all of the various German tribes were united in a single realm. At the age of almost 24, Otto assumed his father's position as Duke of Saxony and King of Germany. His coronation was held on 7 August 936 in Charlemagne's former capital of Aachen, where Otto was anointed and crowned by Hildebert, the Archbishop of Mainz. Though he was a Saxon by birth, Otto appeared at the coronation in Frankish dress in an attempt to demonstrate his sovereignty over the Duchy of Lotharingia and his role as true successor to Charlemagne, whose last heirs in East Francia had died out in 911.According to Widukind of Corvey, Otto had the four other dukes of the kingdom act as his personal attendants at the coronation banquet: Arnulf I of Bavaria as marshal, Herman I, Duke of Swabia as cupbearer, Eberhard of Franconia as steward and Gilbert of Lorraine as Chamberlain. By performing this traditional service, the dukes signaled cooperation with the new king, and clearly showed their submission to his reign.
Despite his peaceful transition, the royal family was not harmonious during his early reign. Otto's younger brother Henry also claimed the throne, contrary to his father's wishes. According to her biography, Vita Mathildis reginae posterior, their mother had favored Henry as king: in contrast to Otto, Henry had been "born in the purple" during his father's reign and shared his name.
Otto also faced internal opposition from various local aristocrats. In 936, Otto appointed Hermann Billung as Margrave, granting him authority over a march north of the Elbe River between the Limes Saxoniae and Peene Rivers. As military governor, Hermann extracted tribute from the Polabian Slavs inhabiting the area and often fought against the Western Slavic tribes of the Lutici, Obotrites, and Wagri. Hermann's appointment angered his brother, Count Wichmann the Elder. As the elder and wealthier of the two, Wichmann believed his claim to the office was superior to his brother's. Additionally, Wichmann was related by marriage to the dowager queen Matilda. In 937, Otto further offended the nobility through his appointment of Gero to succeed his older brother Siegfried as Count and Margrave of a vast border region around Merseburg that abutted the Wends on the lower Saale. His decision frustrated Thankmar, Otto's half-brother and Siegfried's cousin, who felt that he held a greater right to the appointment.
Rebellion of the dukes
Arnulf, Duke of Bavaria, died in 937 and was succeeded by his son Eberhard. The new duke quickly came into conflict with Otto, as Eberhard opposed the king's sovereignty over Bavaria under the peace treaty between King Henry and Arnulf. Refusing to recognize Otto's supremacy, Eberhard rebelled against the king. In two campaigns in the spring and fall of 938, Otto defeated and exiled Eberhard from the kingdom and stripped him of his titles. In his place, Otto appointed Eberhard's uncle Berthold, a count in the March of Carinthia, as the new Duke of Bavaria on the condition that Berthold would recognize Otto as the sole authority to appoint bishops and to administer royal property within the duchy.At the same time, Otto had to settle a dispute between Bruning, a Saxon noble, and Duke Eberhard of Franconia, the brother of the former king Conrad I of Germany. After the rise of a Saxon to kingship, Bruning, a local lord with possessions in the borderland between Franconia and Saxony, refused to swear fealty to any non-Saxon ruler. Eberhard attacked Bruning's Helmern castle near Peckelsheim, killed all of its inhabitants and burned it down. The king called the feuding parties to his court at Magdeburg, where Eberhard was ordered to pay a fine, and his lieutenants were sentenced to carry dead dogs in public, which was considered a particularly shameful punishment.
Infuriated with Otto's actions, Eberhard joined Otto's half-brother Thankmar, Count Wichmann, and Archbishop Frederick of Mainz and rebelled against the king in 938. Duke Herman I of Swabia, one of Otto's closest advisors, warned him of the rebellion and the king moved quickly to put down the revolt. Wichmann was soon reconciled with Otto and joined the king's forces against his former allies. Otto besieged Thankmar at Eresburg and although the latter surrendered, he was killed by a common soldier named Maincia or Meginzo at the altar of the Church of St. Peter. Otto mourned his half-brother and praised his courage but the killer was not punished. Following their defeats, Eberhard and Frederick sought reconciliation with the king. Otto pardoned both after a brief exile in Hildesheim and restored them to their former positions.
