Pietro Tradonicio has to deal not only…
836 CE
Pietro Tradonicio has to deal not only with Saracen pirates, but with Slavs as well.
He leads a large fleet against the Narentines in 839 to punish them for raiding and slaughtering several Venetian traders returning from Benevento in 834–835.
He makes peace with Duke Mislav of the Croats of Dalmatia and a Narentine prince by the name of Družak (Drosaico, Marianorum judice).
