Under international law, an apartheid state is one that maintains an institutionalized regime of systematic oppression and domination by one racial group over another through its laws, policies, and official practices. The apartheid state definition under international law is set out in two treaties: the 1973 International Convention on the Suppression and Punishment of the Crime of Apartheid and the 1998 Rome Statute of the International Criminal Court. Both classify apartheid as a crime against humanity. They differ in how they describe the prohibited conduct and how the crime can be enforced.
The Core Legal Test
The clearest working definition comes from Article 7(2)(h) of the Rome Statute, which describes apartheid as inhumane acts of a character similar to other crimes against humanity, committed in the context of an institutionalized regime of systematic oppression and domination by one racial group over another, with the intention of maintaining that regime.1International Criminal Court. Rome Statute of the International Criminal Court The International Criminal Court’s Elements of Crimes breaks this down into requirements a prosecutor would have to prove.2International Criminal Court. Elements of Crimes
Three elements do the real work.
First, inhumane acts. The perpetrator must have committed an act against one or more persons of the kind listed among crimes against humanity in Article 7(1) of the Rome Statute, or an act of similar nature and gravity. Isolated or minor discriminatory practices do not meet this threshold, however unjust they may be.
Second, an institutionalized regime of systematic oppression. The acts must occur within a deliberate, organized pattern of domination by one racial group over another, embedded in the state’s laws, administrative policies, and official practices. This is what separates apartheid from other forms of discrimination. A state can commit widespread human rights abuses without maintaining the kind of formalized, legally enforced hierarchy that apartheid requires.
Third, intent to maintain the regime. The perpetrator must have intended the conduct to preserve the structure of domination. This is not a general intent to discriminate. Evidence typically comes from the design of laws, patterns of administrative decisions over time, and the overall trajectory of state policy. When the legal system itself enforces the hierarchy through separate citizenship rules, differential access to courts, or restrictions on movement tied to group identity, that pattern speaks to intent.
A fourth contextual requirement applies to all crimes against humanity: the conduct must be part of a widespread or systematic attack directed against a civilian population, and the perpetrator must know it is part of that attack.1International Criminal Court. Rome Statute of the International Criminal Court
What Acts Qualify
The Rome Statute does not list specific apartheid acts. It ties the crime to the broader catalogue in Article 7(1): murder, extermination, enslavement, deportation, imprisonment, torture, sexual violence, persecution, enforced disappearance, and other inhumane acts causing great suffering. Any of these, when committed within the structural context of racial domination and with the intent to preserve it, can constitute apartheid.
The 1973 Apartheid Convention is more concrete. Article II lists six categories of prohibited acts:3University of Minnesota Human Rights Library. International Convention on the Suppression and Punishment of the Crime of Apartheid
- Killing, torture, and arbitrary detention of members of a racial group
- Imposing living conditions designed to cause a group’s physical destruction in whole or in part
- Legislative and other measures preventing a group from participating in political, social, economic, and cultural life, including denial of the right to work, education, freedom of movement, or nationality
- Dividing the population along racial lines through separate residential areas, bans on interracial marriages, or expropriation of land
- Exploiting the labor of a racial group, including forced labor
- Persecuting people and organizations that oppose apartheid
The Convention grew out of the situation in southern Africa, but its drafters wrote it to reach beyond one country. The text covers “similar policies and practices of racial segregation and discrimination as practised in southern Africa.”4United Nations Audiovisual Library of International Law. Convention on the Suppression and Punishment of the Crime of Apartheid Over one hundred states are now party to it. The Rome Statute has 125 states parties, though the United States, Russia, China, and India have not ratified it.5International Criminal Court. The States Parties to the Rome Statute
How Apartheid Differs From Genocide and Persecution
These three crimes can overlap in the facts on the ground, but they are legally distinct. The differences turn on intent and structure.
Genocide requires a specific intent to physically destroy a national, ethnic, racial, or religious group in whole or in part. International lawyers call this dolus specialis, and it is the highest intent threshold of any international crime.6United Nations. Definitions of Genocide and Related Crimes Apartheid does not require intent to destroy a group. Its intent element is the preservation of a regime of domination. Genocide aims to eliminate a group; apartheid aims to keep one group permanently subordinate to another.
Persecution, defined in Article 7(2)(g) of the Rome Statute, is the intentional and severe deprivation of fundamental rights based on group identity.1International Criminal Court. Rome Statute of the International Criminal Court Persecution can target groups defined by politics, nationality, ethnicity, culture, religion, or gender. Apartheid is narrower: it applies only to domination by one racial group over another. Persecution also lacks the structural requirement apartheid demands. A government can persecute a minority through ad hoc crackdowns without maintaining an institutionalized regime; apartheid requires the oppression to be woven into the state’s legal and administrative fabric.
Who Can Be Prosecuted
The 1973 Convention established a form of universal jurisdiction. Any state party can prosecute individuals for the crime regardless of where the acts occurred or where the accused lives, and liability extends to individuals, members of organizations, and state representatives who commit, participate in, or directly encourage apartheid.7University of Oslo Faculty of Law. International Convention on the Suppression and Punishment of the Crime of Apartheid
Under the Rome Statute, Article 25 makes a person liable if they directly commit the crime, order or solicit it, aid or abet it, or contribute to its commission by a group acting with a common purpose.8United Nations. Rome Statute of the International Criminal Court Liability is not limited to heads of state or senior officials.
Military and civilian leaders face additional exposure under Article 28, known as command responsibility. A military commander is criminally responsible for crimes committed by forces under their effective command if the commander knew or should have known and failed to take reasonable measures to prevent them.9Legal Information Institute. Rome Statute of the International Criminal Court, Article 28 Civilian superiors face a similar standard with a slightly different knowledge requirement. Willful blindness at the top of a chain of command does not shield leaders from accountability.
The ICC can impose up to thirty years of imprisonment, or life imprisonment when justified by the extreme gravity of the crime.1International Criminal Court. Rome Statute of the International Criminal Court No individual has ever been prosecuted for apartheid at the ICC or any other international tribunal. The crime exists on the books but has never been tested in a contested criminal proceeding.
What Other States Must Do
When a situation amounts to apartheid, it does not remain the offending state’s internal affair. The prohibition is treated as a peremptory norm of international law, meaning no state can opt out of it through treaties or domestic legislation. That creates obligations owed to the entire international community.
The International Law Commission’s Articles on State Responsibility describe what those obligations require. When a state commits a serious breach of a peremptory norm, all other states must cooperate to bring the breach to an end through lawful means, refuse to recognize the legality of the situation created by the breach, and not render aid or assistance in maintaining it.10United Nations International Law Commission. Responsibility of States for Internationally Wrongful Acts The UN Security Council has authority to impose sanctions, as it did with a mandatory arms embargo against South Africa in 1977.11United Nations. The United Nations in South Africa The International Court of Justice can issue advisory opinions on the legal consequences for other nations, guiding state conduct even when binding Security Council enforcement stalls.
How the Definition Has Been Applied Recently
The most significant recent application came in the International Court of Justice’s advisory opinion of July 19, 2024, on Israel’s policies in the Occupied Palestinian Territory. The Court found that Israel’s legislation and measures impose “a near-complete separation in the West Bank and East Jerusalem between the settler and Palestinian communities,” constituting a breach of Article 3 of the International Convention on the Elimination of All Forms of Racial Discrimination, which is the provision addressing racial segregation and apartheid.12International Court of Justice. Summary of the Advisory Opinion of 19 July 2024 The Court described the restrictions as “systemic discrimination based on, inter alia, race, religion or ethnic origin.”
The President of the Court went further in a separate declaration, stating that Israel’s discriminatory laws and measures “are tantamount to the crime of apartheid,” identifying “numerous inhumane acts” committed as part of “an institutionalized régime of systematic oppression and domination of one racial group over another.”12International Court of Justice. Summary of the Advisory Opinion of 19 July 2024
The opinion activated the obligations framework as well. The Court held that all states are “under an obligation not to recognize as legal the situation arising from the unlawful presence of Israel in the Occupied Palestinian Territory” and must “not render aid or assistance in maintaining” it. Advisory opinions are not technically binding, but they carry legal weight and shape how the law develops. This was the first time the ICJ applied the apartheid framework to an active situation outside of South Africa.
Why the Definition Remains Contested
The definition is clearer on paper than in practice. The three core elements are broad enough that reasonable legal minds disagree about when a state’s policies cross the line from severe discrimination into an institutionalized regime of domination. The term “racial group” is not defined in either the Rome Statute or the 1973 Convention, leaving open questions about how far beyond traditional racial categories the concept extends. The 1973 Convention was drafted with southern Africa explicitly in mind, and some scholars argue its framework does not translate cleanly to conflicts rooted primarily in ethnicity, religion, or nationality.
The absence of any prosecution compounds the uncertainty. Courts have never had to decide, in a contested proceeding with evidence and cross-examination, whether a particular set of state policies meets every element. The 2024 advisory opinion advanced the legal analysis, but advisory opinions do not establish criminal guilt or produce the detailed factual findings a trial would generate. Until a case is brought and adjudicated, the precise boundaries of the crime will remain partly theoretical.
