The pre-Roman period Stobi developed from a Paeonian settlement established in the Archaic period. Located on the northern side of a terrace, the early town covered an area of about 25,000 m2 (270,000 sq ft). Its proximity to the junction of the Erigón and Axiós rivers as well as its position in the fertile central Vardar valley allowed it quickly to develop a flourishing economy and to establish trade. Nearby Mount Klepa was a lucrative source of marble. The initial Paeonian population was later supplemented by other immigrant groups. It is believed that in 217 BCE, Philip V annexed Paionia during his campaign against the Dardans who had entered the largest Paionian town Bylazora.
STOBI WAS IN THE REGION CALLED PAIONIA NOT MACEDON, CONQUERED LATER BY THE ROMANS.
THE BULGARIAN PEOPLE OF FYROM/SKOPJE CAME IN THE REGION FROM VOLGA-STEPPE HUNDREDS OF YEARS LATER
