1870s
Gustav Moynier, one of the founders of the International Committee of the Red Cross, proposed a permanent international court in response to the devastation of the Franco-Prussian War.
1910s
1919
Following World War I, the negotiators of the Treaty of Versailles proposed establishing an international court to try the Kaiser and German war criminals.
Though the Kaiser was never tried, the proposal remained in Article 227 of the Treaty of Versailles.
1940s
1943-1945
The United States and its Allies signed the Moscow Declaration of 1943 and the Potsdam Declaration of 1945, which discussed the need to punish war crimes committed by German and Japanese governments respectively.
1945-1946
Following World War II, the Allies set up the Nuremberg and Tokyo tribunals to try German and Japanese war leaders, respectively. Among other principles, these trials confirmed that individuals could be held criminally responsible for international crimes, regardless of official position, and that superiors’ orders were not a full defense to criminal behavior.
1948
December 9, 1948: The United Nations General Assembly adopted the Convention on the Prevention and Punishment of the Crime of Genocide, which called for perpetrators of genocide to be tried before international penal tribunals. Following the adoption of the Convention, the General Assembly invited the International Law Commission to explore the possibility of establishing an international judicial organ to try those charged with genocide. The Commission concluded that such a judicial organ was both possible and desirable, and a subsequent committee drafted statutes in 1951 and 1954. Despite these early efforts, the General Assembly postponed considering the question, and the Cold War prevented further development of international criminal law for several decades.
1949
August 12, 1949: Led by the International Committee of the Red Cross, a Diplomatic Conference in Geneva, Switzerland adopted the Geneva Conventions of 1949. The original four conventions were followed by Additional Protocols I and II on June 8, 1977. These conventions form the backbone of international humanitarian law and are binding customary international law on all States and other actors in armed conflict. Each convention provides special protection to a group of designated persons, including civilians, aid workers, the wounded, and others no longer taking part in active hostilities. The Fourth Geneva Convention specifically outlines protection owed to civilians in armed conflict. Additionally, the “grave breaches” regime they created (wilful killing, torture or inhuman treatment, causing great suffering or serious injury to body or health, unlawful deportation or transfer of protected persons, hostage-taking, extensive destruction of property, etc.) informed the later codification of war crimes in the Rome Statute.
1960s
May 11, 1960-May 31, 1962
After Israeli secret police arrested him in Argentina, Adolf Eichmann is prosecuted and convicted in Israeli courts for the ruthless extermination of millions of Jews during World War II. It marked the first conviction for genocide (retroactively) and a seminal moment in the use of universal jurisdiction by a national jurisdiction for international atrocity crimes.
1970s
June 8, 1977
Led by the International Committee of the Red Cross, a Diplomatic Conference in Geneva, Switzerland adopted Additional Protocols I and II to the Geneva Conventions of 1949. Protocol I provided additional requirements during international armed conflicts, involving at least two countries, therefore limiting the way wars can be fought. Protocol II provided additional requirements and protection that apply during non-international armed conflicts, or civil wars. Before Protocol II, the only restrictions applicable to internal conflicts were in Common Article Three of the four original Geneva Conventions, which required parties to, at a minimum, protect persons from violence to life and person, humiliating and degrading treatment, and required parties to provide judicial guarantees among other measures.
1980s
June, 1989
Trinidad and Tobago, concerned over the international drug trade, revived the idea of an international criminal court. In response, the United Nations General Assembly asked the International Law Commission to resume its work on drafting a statute for an international criminal court.

1994
November 8, 1994: By resolution, the United Nations Security Council established the International Criminal Tribunal for Rwanda (ICTR) to hold accountable those who participated in the atrocities in Rwanda between January 1 and December 31, 1994. The court was established following an approximately hundred day-long genocide that divided Rwandans largely along ethnic lines.
1995
The International Law Commission presented its final draft statute for an international criminal court to the United Nations General Assembly in 1994. On the Commission’s recommendation, the General Assembly established the Ad Hoc Committee on the Establishment of an International Criminal Court to consider substantives issues in the draft statute. The Ad Hoc Committee met twice during 1995 to discuss the establishment of an international criminal court.
1995-98
The United Nations General Assembly created the Preparatory Committee on the Establishment of the International Criminal Court, open to both Member States and specialized agencies, to prepare a consolidated text based on the International Law Commission’s draft statute and the Ad Hoc Committee’s report. The Preparatory Committee held six sessions between 1996 and 1998, and approved the final draft statute at the March-April meeting in 1998, forming the basis of the draft considered at the Rome Conference.
1997
Dec. 15, 1997: At its 52nd Session, the United Nations General Assembly officially resolved to hold a United Nations Conference of Plenipotentiaries on the Establishment of an International Criminal Court (commonly called the “Rome Conference”), open to all Member States and members of specialized agencies. The General Assembly scheduled their meeting in Rome for June 1998 and tasked the Conference of Plenipotentiaries to finalize and adopt a convention to establish an international criminal court.
1998
June 15 to July 17, 1998: The United Nations Conference of Plenipotentiaries on the Establishment of an International Criminal Court (commonly called the “Rome Conference”) was held with the participation of over 160 governments.
