In 344 BC, Demosthenes barnstormed Peloponnese,[1] in order to detach as many cities as possible from Macedon's influence.
Nonetheless, his mission mainly failed, since most of the Peloponnesians saw Philip as the guarantor of their continued freedom and independence.
Thereby, Philip and certain Peloponnesian cities, including Argos, Messinia and Arcadia, sent a joint embassy to Athens to express their grievances.
In response to the complaints of the Peloponnesian cities, Demosthenes delivered the Second Philippic, a vehement attack against Philip and his Athenian supporters.
[3] According to Demosthenes, his countrymen were misled by Philip's friends, who convinced them that the King of Macedon would save the Phocians and humiliate Thebes.
