Philip V had come to the Macedonian throne in
217 B.C. at the age of 17, and had continued the aggressive policy of his regent, Antigonus. As an ally of the Achaean League, the Macedonians had fought a successful war against the Aetolian League (see Introductory Note), and in
216 B.C. concluded an alliance with Hannibal by a treaty of which Polybius (VII. xix) preserves some clauses. Meanwhile Philip was pursuing an ambitious policy towards Athens and other Greek states. By
214 B.C., Rome seems to have recognized that something like a
state of war
existed (XXIV. xl. 1), but in this passage Livy dates the actual hostilities from
211 B.C., when Rome made a treaty with Philip's old enemies, the Aetolians (XXVI. xxiv. 10). Philip's treaty of peace with the Aetolians is dated
205 B.C. by Livy (XXIX. xii. 1), but we may perhaps explain his
three years
on the assumption that it was not ratified until the next year, Livy's chronology is often confused, as a result of unskilful handling of annalistic sources. The so-called Second Macedonian War, the account of which begins here, was practically ended by the battle of Cynoscephalae in
197 B.C. (XXXIII. vi-x; Polyb. XVIII. xx-xxvii), but lasted diplomatically until
196 B.C. (XXXIII. xxxii). Thereafter Philip pursued a policy of alternating friendship and hostility towards Rome until his death in
179 B.C.
