The Ottonian dynasty was a Saxon dynasty of German monarchs (919–1024), named after three of its kings and Holy Roman emperors, especially Otto the Great. 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 and one of its most common given names. The Ottonian rulers were successors of Conrad I, who was the only German king to rule in East Francia after the Carolingian dynasty.
