For about 400 years, gold flowed out of West Africa to Europe, North Africa, and the Middle East. Most of it came from the kingdoms of the Akan peoples — including the Asante, in what is now Ghana. The gold travelled in the form of dust, not coins. To trade gold dust, you have to weigh it. And the West Africans developed one of the most sophisticated weighing systems in the world. The weights they used were small brass figures, each cast by hand, each weighing a precise, known amount. Some were simple geometric shapes — pyramids, cones, discs. Many were shaped like animals, tools, fruits, people, weapons, household objects. Each shape carried a meaning. Each weight had a name. Many of the names came from Akan proverbs. So a merchant putting a small brass leopard on the scale was not just adding 54 grams. They were also, sometimes, sending a message. The weights are mathematics, money, art, language, and law all in one tiny object. This lesson asks how they worked, what they tell us, and what we lose when an everyday object becomes a curiosity in a museum case.
Several reasons. First: brass is heavy enough to weigh against gold dust without needing huge quantities. Second: brass does not corrode quickly, so the weights stay accurate over decades. Third: each weight can be cast in a specific shape, so no two weights of different values look alike — a merchant can tell at a glance which weight is which. Fourth: the figures are works of art, easy to identify even by an illiterate trader, and they carry meanings that make them part of daily life. Fifth: they can be made in a wide range of sizes, from less than a gram to over 100 grams, allowing very precise weighing. The Akan made hundreds of distinct shapes, each tied to a specific weight. Together, they made up one of the most sophisticated weighing systems anywhere in the pre-modern world. Students should see that this is not 'primitive' technology. It is engineering, mathematics, and art combined into one practical object.
It tells us that trade among the Akan was not just an economic activity. It was also a cultural and moral one. A merchant placing a particular weight on the scale could be sending a coded message — about honesty, about wisdom, about a contract. Some scholars have suggested that a buyer might give a particular gold weight as a kind of warning or compliment to the trading partner. This is the same Akan tradition we see in kente cloth, where each pattern carries a proverb. The same way of thinking — that meaning lives in objects, not just in words — runs through Akan culture. Students should see that the weights are part of a wider pattern. The Akan, like many West African cultures, used objects to speak. Words were not the only way to communicate ideas. End the discovery here. The weights are not exotic. They are just a different, equally precise, system for the same kind of thing words do.
That West Africa was at the centre of global trade for centuries — long before European colonisation, and quite separately from the Atlantic slave trade that came later. Akan gold paid for some of the gold leaf you can still see in old European cathedrals. The wealth of medieval Mali, with its famous king Mansa Musa (who travelled to Mecca in 1324 with so much gold that prices in Egypt fell for years), came from the same region. The Akan goldfields fed a network that ran across the Sahara, around the Mediterranean, and as far as Beijing. The Akan were not isolated. They were a key part of the medieval and early modern world economy. The gold weights are physical evidence of this — they had to be precise enough to satisfy traders from Marrakesh to Cape Coast. Students should see that 'African history' is not separate from 'world history'. They are the same history. The gold weights are one of many proofs.
This is a difficult part of the story but it cannot be skipped. The British wars against Asante were part of the wider European colonisation of Africa in the late 19th century. The taking of gold weights is connected to the same pattern that produced the Benin Bronzes story — military force used to acquire cultural objects, which were then sold or displayed in European museums. The economic cost was real. The cultural cost was also real: an entire system of mathematics, language, and craft was disrupted. Today, modern Asante weavers and craftspeople are reviving some of these traditions, including weight-making. Some museums are returning weights, or at least cataloguing them so that descendants can see what their ancestors made. The weights are still here. The system that depended on them is mostly not. Students should see that 'colonisation' is not just about land. It is also about the small everyday objects that make a culture work — and what happens when those objects are taken away.
Asante gold weights are small brass figures used by the Akan peoples of Ghana and Côte d'Ivoire to weigh gold dust in trade. Each weight was cast by the lost-wax method, in a precise shape, with a known mass — anything from less than half a gram to over 100 grams. Many are figurative — animals, tools, people, weapons — and most carry names linked to Akan proverbs. The system was used for about 400 years, from the 15th century until the late 19th century. The Akan supplied much of the gold that flowed across the Sahara into the Mediterranean and into Europe, making them one of the centres of medieval and early modern global trade. After British attacks on Asante in 1874 and 1896, thousands of weights were taken away and the system slowly fell out of daily use. Today, the weights survive in museums and collections around the world. They are mathematical instruments, works of art, pieces of language, and physical evidence of a major West African trading civilisation.
| Question | What many people assume | What is actually true |
|---|---|---|
| Were the weights just plain metal blocks? | Yes | No — many were carefully cast figures of animals, tools, or scenes from daily life |
| Did West Africa trade with the wider world? | Only after Europeans arrived | For centuries before. Akan gold reached Cairo, Venice, and beyond, mostly across the Sahara |
| Did each weight have a meaning? | They were just measures | Most carried names tied to Akan proverbs. They were objects of language as well as mathematics |
| How precise was the system? | Rough and approximate | Weights ranged from less than 0.5 g to over 100 g, with named values used by traders across regions |
| Why did the system stop being used? | It just became old-fashioned | British wars against Asante in 1874 and 1896 disrupted the kingdom; colonial currency replaced gold dust as money |
West Africa was poor and had little to trade before Europeans arrived.
West African kingdoms supplied much of the gold used in medieval Europe and the Islamic world for over 700 years. The trans-Saharan gold trade made cities like Mali rich and Cairo wealthy. The Akan goldfields were part of this.
Older textbooks often said African history began with European arrival. It did not. The gold weights are physical evidence of an earlier, sophisticated economy.
The gold weights are just ornaments or decorative objects.
They were precise instruments for weighing gold, used in real trade for over 400 years. They were also works of art and carriers of cultural meaning. They are all of these things at once.
'Just' anything is usually wrong with these objects. The Akan combined function and meaning in everyday tools.
The shapes of the weights were random or chosen for fun.
Most shapes carried specific meanings, often tied to Akan proverbs. A weight shaped like a leopard or a bird was not just attractive — it was speaking.
This is part of a wider Akan tradition of putting meaning into objects, also seen in kente cloth and adinkra symbols.
The gold weight system stopped being used because something better came along.
It stopped because British wars against Asante disrupted the kingdom, and colonial currency replaced gold dust as money. Many weights were also taken away in those wars. The system did not 'lose'. It was forced out.
Saying things 'just changed' hides what actually happened. The end of the gold weight system was political, not technological.
This lesson covers a major West African trading culture and the disruption caused by British colonisation. Treat the Akan and Asante peoples as complex, sophisticated, and present-day. Use the proper terms — Akan, Asante (or Ashanti), Asantehene, Kumasi. Do not present pre-colonial Asante as 'primitive'; the kingdom was one of the most powerful and well-organised states in 18th and 19th century Africa. Be honest about the Anglo-Asante wars without dwelling on graphic detail. Do not paint all British people of the 19th century as villains; the wars were specific government decisions, and modern descendants are not personally responsible. When discussing the looting of gold weights, treat it as part of the same wider pattern as the Benin Bronzes story — the wars, the looting, the displacement of objects to European museums. Do not present 'African gold trade' as if it began with Europeans; the trans-Saharan trade is much older and more important. Be aware that some of your students may be of Ghanaian or wider African descent, and the heritage may matter to them personally. Make space for that. Finally, do not call the system 'lost'. The Akan are alive. Some weights are still made. Some weighing traditions are still practised. The system is reduced, not gone.
Answer each question in one or two sentences. Use what you have learned about Asante gold weights.
What is an Asante gold weight, and what was it used for?
Why is it wrong to call the gold weights 'just ornaments'?
How was Akan gold connected to the wider world?
What did the shapes of many gold weights mean?
Why did the Akan gold weight system stop being used?
These questions have no single right answer. Talk in pairs or small groups, then share your ideas with the class.
Should the gold weights taken during the Anglo-Asante wars be returned to Ghana?
In the Akan tradition, an everyday tool can also be a work of art and a carrier of meaning. Are there things in your own life like this?
For 700 years, West African gold helped run the economy of medieval Europe. Most school history books in Europe do not mention this. Why might that be?
