Vojnomir

Vojnomir, Voynomir or Vonomir I was a Slavic military commander in Frankish service, the duke of Slavs in Lower Pannonia, who ruled from c. 790 to c. 800 or from 791 to c. 810 over an area that corresponds to modern-day Slavonia, Croatia.

The Royal Frankish Annals makes mention of a Wonomyrus Sclavus (Vojnomir the Slav) active in 795. Eric of Friuli, sent Vojnomir with his army into Pannonia, between the Danube and Tisza, where they pillaged the Avars' dominions. According to Milko Kos they were not met with serious Avar resistance, and they conquered many forts. The next year the Avars were defeated and Frankish power was extended further east, to the central Danube. Vojnomir's leading position in the campaign has been presumed as very possible with regard to the textual analysis of Annales regni Francorum.

His origin and social position are not mentioned in any contemporary medieval source. His identity has been the subject of several hypotheses.
