The <entity_0> was fought on <entity_2> between the <entity_1> and the <entity_4> of southern Italy and their <entity_3> allies near the Olivento river, in <entity_5>, southern Italy. The <entity_6> had its origin in the decision of Arduin the <entity_3>, a Greek-speaking <entity_3> who had fought for the Byzantines, to change sides and form a coalition with the <entity_4> Rainulf Drengot and the Hauteville brothers (William Iron Arm, Drogo, Humphrey), and the <entity_3> Atenulf of Benevento and Argyrus of Bari. Prior to the <entity_6> Dokeianos sent an envoy to the <entity_3>-Norman army to give them a choice of returning to <entity_3> territory or to fight the numerically superior Byzantine Army. After the envoy was given another horse he was sent back to Dokeianos with the <entity_4>' reply choosing <entity_6>. The <entity_6> of Olivento was the first of the numerous successes scored by the <entity_4> in their conquest of southern Italy.
