Material cultural heritage refers to the physical objects through which societies record, transmit and express their history, beliefs and identity — artifacts, sculptures, masks, textiles, manuscripts, sacred objects, and ceremonial pieces. It is distinct from intangible cultural heritage, which encompasses language, music, oral tradition and living practices. The 2018 Sarr-Savoy Report and this publication address the material — in other words, the tangible objects one can study and display — that left Africa primarily between 1885 and 1960.

The displacement was not accidental. The General Act of the Berlin Conference, signed on February 26, 1885 by nineteen European powers, formalized the colonial partition of Africa and created the conditions under which systematic extraction became not only possible but organized. Military expeditions seized objects as trophies of conquest. Colonial administrators collected on behalf of metropolitan institutions. Missionaries removed what they deemed incompatible with Christian practice. Scientific missions classified and exported objects as ethnographic specimens. Merchants transacted in contexts where the power imbalance was so absolute that consent, where it appeared, could not have been freely given. The vocabulary used at the time — "collecting," "harvesting," "acquiring" — obscured what it was: systematic, near-total plunder of a continent's material cultural heritage.

An estimated 90 to 95% of sub-Saharan Africa's material cultural heritage is held outside the continent. The figure comes from the 2018 Sarr-Savoy Report, commissioned by French President Emmanuel Macron, though the estimate itself is older, drawn from expert calculations that have circulated for decades. This means that African museums and institutions hold between 5% and 10% of their own material cultural heritage. The Digital Benin project, which documents a single category of object from one kingdom, mapped their presence across 131 institutions in 20 countries. While a complete inventory of all institutions holding sub-Saharan African collections would be impossible to reproduce here, the following is a representative selection:

The past decade has produced genuine momentum. In 2022, Germany signed an agreement to transfer legal ownership of over 1,130 Benin Bronzes to Nigeria, with an initial physical handover of 22 objects that December; the Smithsonian repatriated 29 objects the same year. The following year, in November 2023, the Metropolitan Museum of Art transferred three Benin objects to Nigeria's national collections. By June 2025, the Netherlands had transferred 119 Benin Bronzes to Nigeria. Most recently, in February 2026, the University of Cambridge transferred legal ownership of 116 Benin Bronzes to Nigerian authorities, with physical handover still to be arranged. The gap between legal ownership and physical restitution has since become one of the defining tensions in this story.

June 2026 produced the largest single signal yet. At a three-day conference in Accra, the Netherlands presented Ghana's government with a catalog of roughly 2,000 objects from Dutch ethnographic collections under consideration for restitution, though the exact provenance of many objects is still being established.

Germany identified a smaller, more specific set: two war drums and two war horns linked to the Kpando traditional area. Switzerland, in a concurrent development, physically handed over 23 objects to Nigeria on June 29 — 18 Benin Bronzes from three Swiss museums under the Benin Initiative Switzerland (BIS), a collaborative provenance research program launched in 2021, plus 5 additional objects seized in Swiss criminal proceedings.

Denmark, separately, apologized for its role in the transatlantic slave trade and pledged to help preserve Christiansborg Castle, a former slave-trading site it built in 1661.

The restitution conversation is also drawing in actors with no colonial history in Africa. In January 2026, Turkey's ambassador to Nigeria announced that Turkey had identified 76 wooden and metal objects believed to be of Nigerian origin and was ready to begin formal repatriation discussions.

Turkey is not a former colonial power in Africa; it is, however, one of the world's more assertive pursuers of its own looted cultural heritage, having successfully reclaimed objects from the Getty, institutions across Europe, and pressed sustained legal claims against the Metropolitan Museum of Art. Extending the same principle to Nigeria, days before a state visit aimed at deepening bilateral trade, pointed to a broader shift: the restitution conversation is no longer conducted exclusively between African nations and their former Western colonizers.

Convened by Ghana's President John Dramani Mahama in his capacity as African Union Champion on Reparations, the Next Steps Conference on Reparatory Justice brought together heads of state, diplomats, legal experts, academics, civil society leaders and representatives of the African diaspora in Accra from June 17 to 19, 2026.

The conference drew the Prime Minister of Barbados, the President of Senegal, and heads of state from Namibia, Liberia and Sierra Leone, among others. French President Emmanuel Macron addressed the gathering via live video from the Élysée Palace, committing France to a joint Ghana-France Scientific Commission on Slavery.

The conference followed UN Resolution A/RES/80/250, passed on March 25, 2026 and supported by 123 member states, which declared the transatlantic slave trade "the gravest crime against humanity."

Its outcome outlines a broad roadmap covering cultural restitution, financial justice and debt relief, and establishes three international bodies: a Global Advisory Council on Reparatory Justice, an Expert Panel on the Restitution of Cultural Artifacts, and a Panel of Legal Experts.

The returns and pledges of 2026 represent a genuine acceleration from the pace of the prior decade. The disproportion, however, remains. A distinction worth holding: ownership transfers and physical returns are not the same thing. Germany transferred legal ownership of over 1,130 Benin Bronzes to Nigeria in 2022; fewer than 25 have physically left German institutions. Cambridge transferred legal ownership of 116 objects in February 2026; physical handover is still to be arranged. Across all confirmed physical returns since 2021 — from Germany, the Netherlands, Switzerland, France, the Smithsonian, the Horniman Museum and others — fewer than 300 objects have actually been repatriated.

Meanwhile, four institutions alone — the British Museum, the Musée du quai Branly, the Royal Museum for Central Africa in Belgium, and the Humboldt Forum in Berlin — hold a combined total of nearly 400,000 sub-Saharan African objects. The British Museum, which holds approximately 69,000 objects — and the world's largest single collection of Benin Bronzes at around 900 objects — has returned none, citing the British Museum Act 1963, which prohibits permanent deaccessioning without parliamentary action.

France, which pledged in 2017 to return African heritage within five years, indefinitely postponed the enabling legislation in 2024 following resistance in the Senate — and abstained on the UN resolution in March 2026. Macron's June 2026 commitment to a joint Ghana-France Scientific Commission on Slavery is a signal, but it falls short of the legislative action the 2017 pledge required. While the conversation has shifted, the math has not yet caught up.

The scale becomes more legible when measured not in objects but in labor. What sits outside the continent is not a uniform collection — it spans objects produced across dozens of distinct traditions, each the product of a specific body of knowledge transmitted through hereditary guilds, family apprenticeships and generations of accumulated practice.

The methods are as varied as the objects themselves. The lost-wax casting process used by Benin's brass casters — in which a clay core is hand-shaped, coated in beeswax, sculpted in fine detail, encased in layered clay molds, fired to melt the wax away, and broken open to reveal a unique, unrepeatable object — could take months or years for a single commemorative head.

Kente cloth production follows a ten-stage process, from design and naming to the final beating of the material, taking between three weeks and a year to complete.

The illuminated Ge'ez manuscripts of Ethiopia — written in Arabic, Ajami and Ge'ez on parchment prepared from goatskin, scraped, dried and ruled by hand before a single letter was placed — covered medicine, philosophy, law and history, with some dating to the eleventh century. Each page was hand-lettered and illustrated before the volume was bound in wooden covers, sometimes tooled in leather.

Ivory tusks from the Igbesanmwan guild of Benin, some over a meter long, were carved with figures depicting entire royal histories, requiring years of work.

At a conservative estimate of two months of labor per object across the 400,000 held in just four Western institutions — the British Museum, the Musée du quai Branly, the Royal Museum for Central Africa, and the Humboldt Forum — the figure that emerges is over 66,000 years of accumulated human working time.

Written human history spans 5,000 years. The oldest known human artistic expression — a drawing found in Blombos Cave, South Africa — dates back 73,000 years. The scale of what was taken, measured only in labor, places it closer to the earliest marks of human expression than to the beginning of written civilization.

A common argument against restitution has centered on capacity — the suggestion that African institutions are not yet equipped to receive, conserve and steward their own cultural heritage. It is an argument that has circulated in Western museum discourse for decades, often functioning less as a genuine concern than as a reason to deflect.

Ghana's Minister of Tourism, Culture and Creative Arts, Abla Dzifa Gomashie, answered it practically rather than rhetorically: within days of the Accra conference, she met with Lidia Brito, UNESCO's Assistant Director-General for Priority Africa and External Relations, to begin planning storage and conservation infrastructure for the objects under discussion. Professionals at the Ghana Museums and Monuments Board were already undergoing a week-long capacity-building workshop to address skills gaps within the heritage sector. A dedicated national focal team, chaired by archaeologist and University of Ghana professor Kodzo Gavua, had been in place since July 2025, tasked with identifying, documenting and negotiating the return of cultural property held in foreign institutions.

The restitution of objects is not the restoration of a world that existed prior to their extraction. It is something distinct and equally significant: the resumption of a conversation that was interrupted. These objects were not simply taken from communities — they were removed from the process of transmission through which knowledge, identity and meaning are sustained across generations — the thread that makes a culture recognizable to itself across time.

Their absence has not been neutral. A child from Lagos, Bamako or Kinshasa has a better chance of encountering their own cultural heritage in Western countries than at home. Entire generations grew up without direct access to the ingenuity, philosophy and belief of those who came before them. Where that inheritance surfaced at all, it did so severed from the living, intergenerational bond through which such objects speak — one that no institutional framework, however rigorous, can substitute.

Restitution does not resolve that loss. It opens the possibility of a different relationship — one in which communities engage with their own cultural record directly, unmediated by Western institutions. The harder question — what might have been built, understood or carried forward had that interruption never occurred — has no answer, and the absence itself is part of what was taken.
