Why did Philip II and Alexander the Great not conquer Sparta?
Short answerSparta was not worth the effort, and Macedon had better ways to defeat or contain it than fighting it directly.
NotesThe decision reflects strategic prioritization rather than fear of Spartan military reputation. Sparta was not worth the cost and attention of conquest. Philip and Alexander could contain or bypass it through methods more effective than offering the direct fight on which Spartan prestige depended.
