A ceasefire (also known as a truce),
also spelled cease-fire (the
antonym of 'open fire'),
is a stoppage of a
war in which each side agrees with the other to suspend aggressive actions often due to mediation by a third party.
Ceasefires may be between state actors or involve non-state actors.
Ceasefires may be declared as part of a formal
treaty
A treaty is a formal, legally binding written agreement between sovereign states and/or international organizations that is governed by international law. A treaty may also be known as an international agreement, protocol, covenant, convention ...
but also as part of an informal understanding between opposing forces.
They may occur via mediation or otherwise as part of a
peace process
A peace process is the set of political sociology, sociopolitical negotiations, agreements and actions that aim to solve a specific armed conflict.

A ceasefire can be temporary with an intended end date or may be intended to last indefinitely. A ceasefire is distinct from an
armistice
An armistice is a formal agreement of warring parties to stop fighting. It is not necessarily the end of a war, as it may constitute only a cessation of hostilities while an attempt is made to negotiate a lasting peace. It is derived from t ...
in that the armistice is a formal end to a war whereas a ceasefire may be a temporary stoppage.
The immediate goal of a ceasefire is to stop violence but the underlying purposes of ceasefires vary. Ceasefires may be intended to meet short-term limited needs (such as providing humanitarian aid), manage a conflict to make it less devastating, or advance efforts to peacefully resolve a dispute.
An actor may not always intend for a ceasefire to advance the peaceful resolution of a conflict but instead give the actor an upper hand in the conflict (for example, by re-arming and repositioning forces or attacking an unsuspecting adversary), which creates
bargaining problems that may make ceasefires less likely to be implemented and less likely to be durable if implemented.
The durability of ceasefire agreements is affected by several factors, such as demilitarized zones, withdrawal of troops and third-party guarantees and monitoring (e.g.
peacekeeping
Peacekeeping comprises activities, especially military ones, intended to create conditions that favor lasting peace. Research generally finds that peacekeeping reduces civilian and battlefield deaths, as well as reduces the risk of renewed w ...
). Ceasefire agreements are more likely to be durable when they reduce incentives to attack, reduce uncertainty about the adversary's intentions, and when mechanisms are put in place to prevent accidents from spiraling into conflict.
Overview
Ceasefire agreements are more likely to be reached when the costs of conflict are high and when the actors in a conflict have lower
audience cost An audience cost, in international relations theory, is the domestic political cost that leaders incur from their constituency if they escalate a foreign policy crisis and are then seen as backing down. It is considered to be one of the potential me ...
s. Scholars emphasize that war termination is more likely to occur when actors have more information about each other, when actors can make credible commitments, and when the domestic political situation makes it possible for leaders to make war termination agreements without incurring domestic punishment.
By one estimate, there were at least 2202 ceasefires across 66 countries in 109 civil conflicts over the period 1989–2020.
Historical examples
Historically, the concept of a ceasefire existed at least by the time of the Middle Ages, when it was known as a
'truce of God'.
