A common look on war is a series of military campaigns between at least two or more opposing sides involving a dispute over sovereignty, territory, resources, ideology
or a host of other issues. A war to liberate an occupied country is sometimes characterised as a "war of liberation", while a war between internal elements of the same state may constitute a civil war.
Aside from humans and their primate brethren, ants are the only other animals known to exhibit such behavior on a large scale.
A battle is a single engagement fought between two or more parties, wherein each party or aligned group will seek to defeat their opponent. Battles are most often fought during military campaigns and can usually be well defined in time, space and action. Wars are generally the continuum of a related series of battles and are guided by strategy, whereas individual battles are the stage on which tactics are employed.
Military history is the recording and analysis of those events in the history of humanity that fall within the category of organised armed conflict, and that relate to the institutions and organizations that prosecute such conflict.
Epaminondas was a Thebangeneral and statesman who transformed Thebes, leading it out of Spartan subjugation into a preeminent position in Greek geopolitics. In the process he broke Spartan military power with his victory at Leuctra and liberated the Messenianhelots—Peloponnesian Greeks who had been enslaved under Spartan rule for some 200 years. Epaminondas reshaped the political map of Greece, fragmented old alliances, created new ones, and supervised the construction of entire cities. He was militarily influential as well; he invented several major battlefield tactics. Cicero once called him "the first man of Greece", but Epaminondas has fallen into relative obscurity in modern times. The changes he wrought on the Greek political order did not long outlive him, as the cycle of shifting hegemonies and alliances continued unabated. Just 27 years after his death, a recalcitrant Thebes was obliterated by Alexander the Great. Thus Epaminondas—who had been praised in his time as an idealist and liberator—is today largely remembered for a decade (371 to 362 BC) of campaigning that sapped the strength of the great land powers of Greece and paved the way for the Macedonian conquest.
