HIGHLIGHTS

Understanding the Algiers Declaration on the Criminalisation of Colonialism

Introduction

In a significant development in international law and historical justice, the African Union (AU) adopted the Algiers Declaration in February 2026. Officially titled "Towards Redressing the Historical Injustices Through the Criminalisation of Colonialism," the Declaration represents one of the strongest collective efforts by African states to address the legal consequences of colonialism and the transatlantic slave trade.

The Declaration seeks not only to acknowledge the suffering caused by colonial rule but also to establish a legal framework through which historical injustices can be recognised, remedied, and potentially prosecuted under international law.

Background of the Declaration

Origin of the Initiative

• In December 2025, scholars, legal experts, policymakers, and representatives from various countries gathered in Algiers, Algeria, at the International Conference on the Crimes of Colonialism.
• The purpose of the conference was to examine whether colonial practices should be formally recognised as international crimes.
• Participants drafted a document calling for stronger legal recognition of colonial-era abuses and their continuing consequences.

Adoption by the African Union

• In February 2026, the African Union officially adopted the document.
• The adopted text became known as the Algiers Declaration.
• The Declaration reflects a continent-wide position on the need to address the legacy of colonialism through international legal mechanisms.

Colonialism as an International Crime

One of the most important aspects of the Declaration is its legal classification of colonial practices.

Crimes Against Humanity

The Declaration states that colonialism involved:

• Systematic oppression of populations.
• Forced labour and exploitation.
• Mass displacement of communities.
• Cultural destruction and suppression of indigenous identities.

According to the Declaration, these actions fit within the modern legal definition of crimes against humanity because they involved widespread and systematic attacks against civilian populations.

Genocide and Related Crimes

The Declaration further argues that certain colonial policies amounted to forms of genocide because they:

• Destroyed indigenous populations.
• Eliminated traditional cultures and languages.
• Caused mass deaths through violence, starvation, and forced displacement.

The document also places the following historical practices within this legal framework:

• The transatlantic slave trade.
• Forced deportations.
• Apartheid systems.
• Other forms of racial domination and exploitation.

The Principle of Imprescriptibility

A key legal concept emphasised by the Declaration is imprescriptibility.

What Does Imprescriptibility Mean?

• Certain international crimes are considered so serious that they never become legally obsolete.
• There is no statute of limitations for such crimes.
• The passage of time does not erase responsibility.

Why Is This Important?

The Declaration argues that:

• Colonial crimes should not be treated differently from genocide, war crimes, or crimes against humanity.
• Historical distance should not prevent victims or their descendants from seeking justice.
• Legal accountability can still be pursued even when the events occurred generations ago.

This position is intended to strengthen demands for recognition, accountability, and reparations.

Codifying Colonial Crimes in International Law

The Declaration calls for colonialism to be formally incorporated into international legal instruments.

Need for Legal Recognition

At present:

• International law criminalises genocide, war crimes, aggression, and crimes against humanity.
• Colonialism itself is not expressly listed as an independent international crime.

The Declaration seeks to change this situation by encouraging states and international organisations to:

• Develop new treaties.
• Amend existing legal instruments.
• Create stronger legal standards regarding colonial-era abuses.

Further Legal Research

The document also urges:

• International organizations.
• Academic institutions.
• Human rights bodies.

to conduct deeper legal studies demonstrating how colonial practices fit within existing international criminal law categories.

Restitution of Cultural Property and Human Remains

Another major focus of the Declaration concerns the return of property taken during colonial rule.

Return of Cultural Heritage

The Declaration demands the restitution of:

• Cultural artifacts.
• Historical documents.
• Archives.
• Sacred objects.

Many African states argue that these items were removed without consent and now remain in foreign museums and institutions.

Return of Human Remains

The document also seeks the repatriation of human remains taken during colonial periods for scientific, military, or exhibition purposes.

According to the Declaration:

• Human remains should be returned to their communities of origin.
• Such returns are necessary for dignity, healing, and historical justice.

Reparatory Justice

The Declaration goes beyond symbolic recognition and focuses on practical remedies.

Continuing Effects of Colonialism

The document argues that colonialism continues to affect Africa through:

• Economic inequalities.
• Underdevelopment.
• Social disruption.
• Environmental damage.
• Structural poverty.

According to the Declaration, these are not merely historical issues but continuing consequences of colonial systems.

Forms of Reparations

The Declaration encourages coordinated efforts to pursue:

• Financial compensation.
• Development assistance.
• Institutional reforms.
• Educational initiatives.
• Cultural restoration programs.

The goal is not only to compensate for past harms but also to address present-day inequalities linked to colonial exploitation.

Reform of Global Institutions

The Declaration connects reparations with broader international reform.

Structural Change

According to the document:

• Historical injustices are embedded within current global economic structures.
• Meaningful reparations require changes to international systems that continue to disadvantage colonised nations.

Areas of Reform

The Declaration calls for discussions regarding:

• International financial institutions.
• Global trade systems.
• Economic governance structures.
• Decision-making processes in international organizations.

The argument is that justice cannot be fully achieved unless these broader structural issues are addressed.

Significance of the Algiers Declaration

The Algiers Declaration represents a major political and legal statement by African states.

Its significance lies in:

• Recognising colonialism as a serious international wrong.
• Expanding debates on historical accountability.
• Strengthening demands for restitution and reparations.
• Encouraging the development of new international legal norms.
• Creating a unified continental position on colonial justice.

Although the Declaration itself is not legally binding, it may influence future international negotiations, legal scholarship, and treaty development.

Conclusion

The Algiers Declaration marks an important step in Africa’s effort to seek recognition of the harms caused by colonialism and the transatlantic slave trade. By characterising colonial practices as crimes against humanity and forms of genocide, emphasising their imprescriptible nature, and demanding restitution and reparatory justice, the Declaration seeks to reshape international discussions on historical accountability.

Whether its proposals ultimately become part of binding international law remains uncertain. However, the Declaration has already established an important legal and political framework for future debates on colonial responsibility, reparations, and global justice. It stands as a significant continental initiative aimed at ensuring that historical injustices are neither forgotten nor excluded from the pursuit of international justice.
