between relatively large groups of people (such as nations
, social groups
), which is characterized by the use of armed lethal violence
or upon civilians

, include armed conflict, hostilities, and police action
A common perception of 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 species 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.
was an Athenian general
leader. In 411 BC, in the wake of an oligarchic coup
at Athens, the pro-democracy sailors at Samos
elected him as a general, making him a primary leader of the successful democratic resistance to that coup. As general, he was responsible for recalling the controversial nobleman Alcibiades
from exile, and the two worked together extensively over the next several years. In 411 and 410, Thrasybulus commanded several critical Athenian naval victories, along with Alcibiades and others. After Athens' defeat in the Peloponnesian War
, Thrasybulus led the democratic resistance to the new oligarchic government, known as the Thirty Tyrants
, that the victorious Spartans
imposed on Athens. In 404 BC, he commanded a small force of exiles that invaded Attica
and, in successive battles, defeated first a Spartan garrison and then the forces of the oligarchics. In the wake of these victories, democracy was reestablished in Athens. As a leader of this revived democracy in the 4th century BC, Thrasybulus advocated a policy of resistance to Sparta and sought to restore Athens' imperial power. He was killed in 388 BC while leading an Athenian naval force in the Corinthian War
