Following the peace treaty, Philip cooperated with the Romans and provided material support for their wars against the Spartans under Nabis in 195 BC. Philip V also supported the Romans against Antiochus III the Great and the Aetolian League. After the Roman–Seleucid War the Romans allowed Philip V to keep territory he had conquered, such as Demetrias, the Magnesian coastline of Thessaly, parts of Athamania, parts of Dolopia, parts of Perrhaebia, and a number of towns in the Malian Gulf.
