Ottonian Illuminated Manuscripts

The Ottonian dynasty (german: Ottonen) was a Saxon dynasty of German monarchs (919–1024), named after three of its kings and Holy Roman Emperors named Otto, especially its first Emperor Otto I. It is also known as the Saxon dynasty after the family's origin in the German stem duchy of Saxony. The family itself is also sometimes known as the Liudolfings (), after its earliest known member Count Liudolf (d. 866) and one of its most common given names. The Ottonian rulers were successors of the Germanic king Conrad I, who was the only Germanic king to rule in East Francia after the Carolingian dynasty and before this dynasty.

The Ottonians are associated with the notable military success that transformed the political situation in contemporary Western Europe: "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." They are also associated with a notable cultural movement (especially new literary traditions) known as the Ottonian Renaissance.

After the end of Ottonian rule in 1024, the Salian dynasty went on to occupy the Imperial throne for just over a century, until 1125.

Origins

In the 9th century, the Saxon count Liudolf held large estates on the Leine river west of the Harz mountain range and in the adjacent Eichsfeld territory of Thuringia. His ancestors probably acted as ''ministeriales'' in the Saxon stem duchy, which had been incorporated into the Carolingian Empire after the Saxon Wars of Charlemagne. Liudolf married Oda, a member of the Frankish House of Billung. About 852 the couple together with Bishop Altfrid of Hildesheim founded Brunshausen Abbey, which, once relocated to Gandersheim, rose to a family monastery and burial ground.

Liudolf already held the high social position of a Saxon ''dux'', documented by the marriage of his daughter Liutgard with Louis the Younger, son of the Carolingian king Louis the German in 869. Liudolf's sons Bruno and Otto the Illustrious ruled over large parts of Saxon Eastphalia, moreover, Otto acted as lay abbot of the Imperial abbey of Hersfeld with large estates in Thuringia. He married Hedwiga, a daughter of the Babenberg duke Henry of Franconia. Otto possibly accompanied King Arnulf on his 894 campaign to Italy; the marriage of his daughter Oda with Zwentibold, Arnulf's illegitimate son, documents the efforts of the Carolingian ruler to win the mighty Saxon dynasty over as an ally. According to the Saxon chronicler Widukind of Corvey, Otto upon the death of the last Carolingian king Louis the Child in 911 was already a candidate for the East Frankish crown, which however passed to the Franconian duke Conrad I.

Upon Otto's death in 912, his son Henry the Fowler succeeded him as Duke of Saxony. Henry had married Matilda of Ringelheim, a descendant of the legendary Saxon ruler Widukind and heiress to extended estates in Westphalia.

Ottonian kings and emperors

The Ottonian rulers of East Francia, the German kingdom, and the Holy Roman Empire were:
* Henry the Fowler (Henry I), Duke of Saxony from 912, King of East Francia from 919 until 936
* Otto I, ''the Great'', Duke of Saxony and King of East Francia from 936, King of Italy from 951, Holy Roman Emperor from 962 until 973
* Otto II, co-ruler from 961, Holy Roman Emperor from 967, sole ruler from 973 until 983
* Otto III, King of the Romans from 983, Holy Roman Emperor from 996 until 1002
* Henry II, ''the Saint'', Duke of Bavaria from 995 (as Henry IV), King of the Romans from 1002, King of Italy from 1004, Holy Roman Emperor from 1002 until 1024

Henry I

Although never Emperor, Henry the Fowler was arguably the founder of the imperial dynasty. While East Francia under the rule of the last Carolingian kings was ravaged by Hungarian invasions, he was chosen to be '' primus inter pares'' among the German dukes. Elected ''Rex Francorum'' in May 919, Henry abandoned the claim to dominate the whole disintegrating Carolingian Empire and, unlike his predecessor Conrad I, succeeded in gaining the support of the Franconian, Bavarian, Swabian and Lotharingian dukes. In 933 he led a German army to victory over the Hungarian forces at the Battle of Riade and campaigned both the land of the Polabian Slavs and the Duchy of Bohemia. Because he had assimilated so much power through his conquest, he was able to transfer power to his second son Otto I.

Otto I

Otto I, Duke of Saxony upon the death of his father in 936, was elected king within a few weeks. He continued the work of unifying all of the German tribes into a single kingdom, greatly expanding the powers of the king at the expense of the aristocracy. Through strategic marriages and personal appointments, he installed members of his own family in the kingdom's most important duchies. This, however, did not prevent his relatives from entering into civil war: both Otto's brother Duke Henry of Bavaria and his son Duke Liudolf of Swabia revolted against his rule. Otto was able to suppress their uprisings, in consequence, the various dukes, who had previously been co-equals with the king, were reduced to royal subjects under the king's authority. His decisive victory over the Magyars at the Battle of Lechfeld in 955 ended the Hungarian invasions of Europe and secured his hold over his kingdom.

The defeat of the pagan Magyars earned King Otto the reputation as the savior of Christendom and the epithet "the Great". He transformed the Church in Germany into a kind of proprietary church
