Evropos in the context of "Kilkis (regional unit)"

In antiquity, Paeonia or Paionia (Ancient Greek: Παιονία, romanized: Paionía) was the land and kingdom of the Paeonians (or Paionians; Ancient Greek: Παίονες, romanized: Paíones).

The exact original boundaries of Paeonia, like the early history of its inhabitants, are obscure, but it is known that it roughly corresponds to most of present-day North Macedonia and north-central parts of Greek Macedonia before the expansion of Macedon (i.e. probably the Greek municipalities of Paionia (excluding the village of Evropos), Almopia, Sintiki, Irakleia, and Serres), and a small part of south-western Bulgaria. Ancient authors placed it south of Dardania (an area corresponding to modern-day Kosovo and northern North Macedonia), west of the Thracian mountains, and east of the southernmost Illyrians. It was separated from Dardania by the mountains through which the Vardar river passes from the field of Scupi (modern Skopje) to the valley of Bylazora (near modern Sveti Nikole).
