The Euboean League in 218 B.C.

The Euboean League — Antigonid Macedon.

The long island of Euboea, its cities leagued under Macedonian protection and dominated by the garrison of Chalcis. Euboea guards the eastern flank of the Greek mainland and the Aegean sea-road, and its loyalty is held fast by the fetter on the Euripus.
