 Between 887 and 948, no new war was recorded between Venice and the Croats, which assumed that Venetians paid tribute to maintain the peace.In the work of Constantine Porphyrogenitus, "De administrando imperio" it is stated that Croatia, during the reign of King Tomislav had 80 "sagenas" (larger ships with 40 sailors) and 100 (smaller ships with 10 to 20 sailors, not counting oarsmen).The era of King Stjepan Držislav (969-996) was marked with successful maritime trade and safekeeping of maritime routes and domination of Croatia on the eastern coast of the Adriatic Sea.
