 These tactics inspired the future king Philip II of Macedon, who was at the time a hostage in Thebes, also inspired the development of new type of infantry, the Macedonian phalanx.After the Macedonian conquests of the 4th century BC, the hoplite was slowly abandoned in favour of the phalangite, armed in the Macedonian fashion, in the armies of the southern Greek states.Although clearly a development of the hoplite, the Macedonian phalanx was tactically more versatile, especially used in the combined arms tactics favoured by the Macedonians.
