I want to know the answer to the following question:
When did Philip form and alliance with Hannibal of Carthage?
All the background I'm provided with is that "In 215 BC Philip, with his eye on Illyria, formed an alliance with Rome's enemy Hannibal of Carthage, which led to Roman alliances with the Achaean League, Rhodes and Pergamum.". Is that enough to answer the question?
Answer: yes
