The '''Battle of Mantinea''' in 418 B.C. was part of the [[Second Peloponnesian War]] between the [[Greek]] [[city states]] of [[Athens]] and [[Sparta]] and their allies. The Spartan King [[Agis]] invaded the allies of Athens [[Argos]] and [[Matinea]]. Athens sent a small force to assist, but the allied army was badly beaten by the Spartans. This, the largest land battle of the war, took place when the opposing forces were nominally at peace. Sparta had restored itself to unquestioned hegemony of the Peloponnesus. | The '''Battle of Mantinea''' in 418 B.C. was part of the [[Second Peloponnesian War]] between the [[Greek]] [[city states]] of [[Athens]] and [[Sparta]] and their allies.
