The region of Narentines occupied the area between the Neretva and Cetina rivers, and consisted of three "župas", Rastoc and Mokro on the coast, and Dalen, in the hinterland. The first two had fleets, while the third was agricultural. The Narentines also held islands of Mljet, Korčula, Brač and Hvar, left vacant by the Romanized population, but inhabited by the Narentines who kept herds there. They weren't Christianized with the rest of the Serbian tribes, hence the Greeks called them Pagans. Venetian chronicler John the Deacon mentions the visit of the Narenties party to Venice in c. 830, which were still not Christianized, so they were baptized in Venice. The accord reached between the Narentines and Venetians wasn't lasting, as in 835 the Narentines again started to attack Venetian merchants and missionaries. Venetian dodge Pietro Tradonico sent fleet in 839 to the Balkan coast of the Adriatic, reaching peace with duke Mislav of the Dalmatian Croatia, and alliance ("foedus") with Družak, Narentine chieftain. This didn't last either, and next year the dodge sent another fleet, but was defeated by the Narentines.
