Factors Ending A War

The political and economic circumstances, in the peace that follows war, usually depend on the facts on the ground. Where evenly matched adversaries decide that the conflict has resulted in a stalemate, they may cease hostilities to avoid further loss of life and property. They may decide to restore the antebellum territorial boundaries, redraw boundaries at the line of military control, or negotiate to keep or exchange captured territory. Negotiations between parties involved at the end of a war often result in a treaty, such as the Treaty of Versailles of 1919, which ended the First World War.

A warring party that surrenders or capitulates may have little negotiating power, with the victorious side either imposing a settlement or dictating most of the terms of any treaty. A common result is that conquered territory is brought under the dominion of the stronger military power. An unconditional surrender is made in the face of overwhelming military force as an attempt to prevent further harm to life and property. For example, the Empire of Japan gave an unconditional surrender to the Allies of World War II after the atomic bombings of Hiroshima and Nagasaki (see Surrender of Japan), the preceding massive strategic bombardment of Japan and declaration of war and the immediate invasion of Manchuria by the Soviet Union. A settlement or surrender may also be obtained through deception or bluffing.

Many other wars, however, have ended in complete destruction of the opposing territory, such as the Battle of Carthage of the Third Punic War between the Phoenician city of Carthage and Ancient Rome in 149 BC. In 146 BC the Romans burned the city, enslaved its citizens, and razed the buildings.

Some wars or aggressive actions end when the military objective of the victorious side has been achieved. Others do not, especially in cases where the state structures do not exist, or have collapsed prior to the victory of the conqueror. In such cases, disorganised guerilla warfare may continue for a considerable period. In cases of complete surrender conquered territories may be brought under the permanent dominion of the victorious side. A raid for the purposes of looting may be completed with the successful capture of goods. In other cases an aggressor may decide to end hostilities to avoid continued losses and cease hostilities without obtaining the original objective, such as happened in the Iran–Iraq War.

Some hostilities, such as insurgency or civil war, may persist for long periods of time with only a low level of military activity. In some cases there is no negotiation of any official treaty, but fighting may trail off and eventually stop after the political demands of the belligerent groups have been reconciled, a political settlement has been negotiated, the combatants are gradually killed or decide the conflict is futile, or the belligerents cease active military engagement but still threaten each other. An example is the Chinese Civil War which essentially ceased by 1950 but the People's Republic of China fought diplomatically to isolate Taiwan, but it still threatens Republic of China (commonly known as Taiwan) with an invasion. For this reason, some historians consider the war not ended but continuing.
