International humanitarian law (IHL), often referred to as the laws of war, the laws and customs of war or the law of armed conflict, is the legal corpus that comprises "the Geneva Conventions and the Hague Conventions, as well as subsequent treaties, case law, and customary international law." It defines the conduct and responsibilities of belligerent nations, neutral nations and individuals engaged in warfare, in relation to each other and to protected persons, usually meaning civilians.
The law is mandatory for nations bound by the appropriate treaties. There are also other customary unwritten rules of war, many of which were explored at the Nuremberg War Trials. By extension, they also define both the permissive rights of these powers as well as prohibitions on their conduct when dealing with irregular forces and non-signatories.

Two Historical Streams: The Law of Geneva and The Law of The Hague
Modern International Humanitarian Law is made up of two historical streams: the law of The Hague referred to in the past as the law of war proper and the law of Geneva or humanitarian law. The two streams take their names from a number of international conferences which drew up treaties relating to war and conflict, in particular the Hague Conventions of 1899 and 1907, and the Geneva Conventions, the first which was drawn up in 1863. Both are branches of jus in bello, international law regarding acceptable practices while engaged in war and armed conflict.
The Law of The Hague, or the Laws of War proper,"determines the rights and duties of belligerents in the conduct of operations and limits the choice of means in doing harm."  In particular, it concerns itself with the definition of combatants, establishes rules relating to the means and methods of warfare, and examines the issue of military objectives.
Main article: Laws of War
Systematic attempts to limit the savagery of warfare only began to develop in the 19th century. Such concerns were able to build on the changing view of warfare by states influenced by the Age of Enlightenment. The purpose of warfare was to overcome the enemy state and this was obtainable by disabling the enemy combatants. Thus, "(t)he distinction between combatants and civilians, the requirement that wounded and captured enemy combatants must be treated humanely, and that quarter must be given, some of the pillars of modern humanitarian law, all follow from this principle."
The Law of Geneva
The massacre of civilians in the midst of armed conflict has a long and dark history. Selected examples include: Moses, speaking for the god of the Israelites, ordering the killing of all the Midianite women and male children; the massacres of the Kalingas by Ashoka in India, the massacre of some 100,000 Hindus by the Muslim troops of Timur (Tamerlane) or the Crusader massacres of Jews and Muslims in the Siege of Jerusalem (1099), to name a few examples drawn from a long list in history. Fritz Munch sums up historical military practice before 1800: "The essential points seem to be these: In battle and in towns taken by force, combatants and non-combatants were killed and property was destroyed or looted. In the 17th century, the Dutch jurist Hugo Grotius wrote "Wars, for the attainment of their objects, it cannot be denied, must employ force and terror as their most proper agents."
Humanitarian Norms in History
However, even in the midst of the carnage of history, there were expressions of humanitarian norms to protect the victims of armed conflicts, i.e. the wounded, the sick and the shipwrecked which date back to ancient times.
In the Old Testament, the King of Israel prevents the slaying of the captured following the prophet, Elisha's admonition, to spare enemy prisoners: In answer to a question from the King, he said, "You shall not slay them. Would you slay those whom you have taken captive with your sword and with your bow? Set bread and water before them, that they may eat and drink and go to their master.”
In ancient India there are records, for example the Laws of Manu, describing the types of weapons that should not be used. "When he fights with his foes in battle, let him not strike with weapons concealed (in wood), nor with (such as are) barbed, poisoned, or the points of which are blazing with fire. There is also the command not to strike a eunuch nor the enemy "who folds his hands in supplication....Nor one who sleeps, nor one who has lost his coat of mail, nor one who is naked, nor one who is disarmed, nor one who looks on without taking part in the fight...".
Islamic law indicates that "noncombatants who did not take part in fighting such as women, children, monks and hermits, the aged, blind, and insane" were not to be molested. The first Caliph, Abu Bakr, proclaimed "Do not mutilate. Do not kill little children or old men or women. Do not cut off the heads of palm trees or burn them. Do not cut down fruit trees. Do not slaughter livestock except for food." Islamic jurists have held that a prisoner should not be killed as he "cannot be held responsible for mere acts of belligerency."  Islamic law did not spare all non-combatants. In the case of those who refused to convert to Islam or pay an alternative tax, Muslims "were allowed in principle to kill any one of them, combatants or noncombatants, provided they were not killed treacherously and with mutilation."
Codification of Humanitarian Norms
However, it was not till the second half of the 19th century that a more systematic approach was initiated. In the United States, a German immigrant, Francis Lieber, drew up a code of conduct in 1863, which came to be called the Lieber Code in his honor, for the Northern army. The Lieber Code included the humane treatment of civilian populations in the areas of conflict, and also forbade the execution of POWs. At the same time, the involvement of a number of individuals such as Florence Nightingale during the Crimean War and Henry Dunant, a Genevese businessman who had worked with wounded soldiers at the Battle of Solferino, led to more systematic efforts to try and prevent the suffering of war victims. Dunant wrote a book, which he titled A Memory of Solferino, and in which he described the horrors he had witnessed. His reports were so shocking that they led to the founding of the International Committee of the Red Cross (ICRC) in 1863 and the convening of a conference in Geneva in 1864 which drew up the Geneva Convention for the Amelioration of the Condition of the Wounded in Armies in the Field.
The Law of Geneva is directly inspired by the principle of humanity. It relates to those who are not participating in the conflict as well as military personnel hors de combat. It provides the legal basis for protection and humanitarian assistance carried out by impartial humanitarian organizations such as the ICRC. This focus can be found in the Geneva Conventions.
 Geneva Conventions
Original Geneva Convention in 1864.
Progression of Geneva Conventions from 1864 to 1949.
The Geneva Conventions are the result of a process that developed in a number of stages between 1864 and 1949 which focused on the protection of civilians and those who can no longer fight in an armed conflict. As a result of World War II, all four conventions were revised based on previous revisions and partly on some of the 1907 Hague Conventions and readopted by the international community in 1949. Later conferences have added provisions prohibiting certain methods of warfare and addressing issues of civil wars.
The Geneva Conventions are:
* First Geneva Convention "for the Amelioration of the Condition of the Wounded and Sick in Armed Forces in the Field" (first adopted in 1864, last revision in 1949)
* Second Geneva Convention "for the Amelioration of the Condition of Wounded, Sick and Shipwrecked Members of Armed Forces at Sea" (first adopted in 1949, successor of the 1907 Hague Convention X)
* Third Geneva Convention "relative to the Treatment of Prisoners of War" (first adopted in 1929, last revision in 1949)
* Fourth Geneva Convention "relative to the Protection of Civilian Persons in Time of War" (first adopted in 1949, based on parts of the 1907 Hague Convention IV)
In addition, there are three additional amendment protocols to the Geneva Convention:
* Protocol I (1977): Protocol Additional to the Geneva Conventions of 12 August 1949, and relating to the Protection of Victims of International Armed Conflicts. As of 12 January 2007 it had been ratified by 167 countries.
* Protocol II (1977): Protocol Additional to the Geneva Conventions of 12 August 1949, and relating to the Protection of Victims of Non-International Armed Conflicts. As of 12 January 2007 it had been ratified by 163 countries.
* Protocol III (2005): Protocol Additional to the Geneva Conventions of 12 August 1949, and relating to the Adoption of an Additional Distinctive Emblem. As of June 2007 it had been ratified by 17 countries and signed but not yet ratified by an additional 68 countries.
While the Geneva Conventions of 1949 can be seen as the result of a process which began in 1864, today, they have "achieved universal participation with 194 parties." This means that they apply to almost any international armed conflict.
 Historical Convergence between IHL and the Laws of War
With the adoption of the 1977 Additional Protocols to the Geneva Conventions, the two strains of law began to converge, although provisions focusing on humanity could already be found in the Hague law (i.e. the protection of certain prisoners of war and civilians in occupied territories). However the 1977 Additional Protocols relating to the protection of victims in both international and internal conflict not only incorporated aspects of both the Law of The Hague and the Law of Geneva, but also important human rights provisions.
 Basic rules of IHL
1. Persons hors de combat (outside of combat) and those not taking part in hostilities shall be protected and treated humanely.
2. It is forbidden to kill or injure an enemy who surrenders or who is hors de combat.
3. The wounded and sick shall be cared for and protected by the party to the conflict which has them in its power. The emblem of the "Red Cross," or of the "Red Crescent," shall be required to be respected as the sign of protection.
4. Captured combatants and civilians must be protected against acts of violence and reprisals. They shall have the right to correspond with their families and to receive relief.
5. No one shall be subjected to torture, corporal punishment or cruel or degrading treatment.
6. Parties to a conflict and members of their armed forces do not have an unlimited choice of methods and means of warfare.
7. Parties to a conflict shall at all times distinguish between the civilian population and combatants. Attacks shall be directed solely against military objectives.
Well-known examples of such rules include the prohibition on attacking doctors or ambulances displaying a Red Cross. It is also prohibited to fire at a person or vehicle bearing a white flag, since that, being considered the flag of truce, indicates an intent to surrender or a desire to communicate. In either case, the persons protected by the Red Cross or the white flag are expected to maintain neutrality, and they may not engage in warlike acts themselves; in fact, engaging in war activities under a white flag or a red cross is itself a violation of the laws of war.
These examples of the laws of war address declaration of war, (the UN charter (1945) Art 2, and some other Arts in the charter, curtails the right of member states to declare war; as does the older and toothless Kellogg-Briand Pact of 1928 for those nations who ratified it but used against Germany in the Nuremberg War Trials), acceptance of surrender and the treatment of prisoners of war; the avoidance of atrocities; the prohibition on deliberately attacking civilians; and the prohibition of certain inhumane weapons. It is a violation of the laws of war to engage in combat without meeting certain requirements, among them the wearing of a distinctive uniform or other easily identifiable badge and the carrying of weapons openly. Impersonating soldiers of the other side by wearing the enemy's uniform, and fighting in that uniform, is forbidden, as is the taking of hostages.

The ICRC is the only institution explicitly named under international humanitarian law as a controlling authority. The legal mandate of the ICRC stems from the four Geneva Conventions of 1949, as well as its own Statutes.
“ The International Committee of the Red Cross (ICRC) is an impartial, neutral, and independent organization whose exclusively humanitarian mission is to protect the lives and dignity of victims of war and internal violence and to provide them with assistance. ”
—Mission of ICRC
Violations and punishment
During conflict, punishment for violating the laws of war may consist of a specific, deliberate and limited violation of the laws of war in reprisal.
Soldiers who break specific provisions of the laws of war lose the protections and status afforded as prisoners of war but only after facing a "competent tribunal" (GC III Art 5). At that point they become an unlawful combatant but they must still be "treated with humanity and, in case of trial, shall not be deprived of the rights of fair and regular trial", because they are still covered by GC IV Art 5.
Spies and terrorists are only protected by the laws of war if the power which holds them is in a state of armed conflict or war and until they are found to be an unlawful combatant. Depending on the circumstances, they may be subject to civilian law or military tribunal for their acts and in practice have been subjected to torture and/or execution. The laws of war neither approve nor condemn such acts, which fall outside their scope. Countries that have signed the UN Convention Against Torture have committed themselves not to use torture on anyone for any reason.
After a conflict has ended, persons who have committed any breach of the laws of war, and especially atrocities, may be held individually accountable for war crimes through process of law.
