The so-called “Mithridatic Wars” had the nature and scale of a world war in terms of the Antiquity. The Left Pont was directly affected by the state of war and felt its consequences. In particular the outcome of the battle of Chaeronea, in the year 86 BC, when the Getic leader Dromichaites (a different character than Lysimachus’s opponent at the turn of the IV / III BC centuries) and the military body he ordered disappeared, created circumstances that motivated Deceneu to conclude an alliance with Burebista.
