As a consequence of the growth of Macedonian power, and under pressure from their Thracian neighbors, their territory was considerably diminished, and in historical times was limited to the north of Macedonia from Illyria to the Strymon.
Как следствие роста Македонии и под давлением своих фракийских соседей, территория пеонов была значительно урезана и в историческую эпоху была ограничена к северу от Македонии, от Иллирии до реки Стримонас.
