When Hugh Masekela released Stimela, he did more than tell the story of a train. He captured the rhythm of a continent whose people have always been in motion. He was documenting a chapter of African history that deserves to be remembered.

The train carried men from across Southern Africa to work in South Africa’s mines. They came from what is now Zimbabwe, Mozambique, Malawi, Lesotho, Zambia, Eswatini, Namibia, DR Congo and beyond, leaving families behind, in search of opportunity.

Their labour helped build one of Africa’s largest economies, while their sacrifices shaped countless communities across the region. Today, Stimela feels less like a song about the past and more like a reminder of something Africa risks forgetting.

Long before colonial borders divided the continent into modern states, Africans moved. Traders crossed kingdoms. Craftsmen travelled with their skills. Communities exchanged ideas, goods and culture. Families settled beyond what are now national boundaries, while rivers and trade routes connected people more often than they separated them. Movement was not the exception. It was part of how African societies functioned.

Today’s borders serve important political purposes, but they do not erase relationships that existed long before they were drawn. Across the continent, communities still share languages, traditions and histories that extend beyond national boundaries.

This history matters because the continent is once again talking about integration. Through the African Continental Free Trade Area, regional economic communities and growing cross-border investment, Africa is attempting to strengthen the movement of goods, services, capital and ideas. These initiatives are often described as ambitious new projects, yet they are also a return to something the continent understood long ago: prosperity grows when people and opportunity can move.

Yet movement has never been only about economics. It has always been about people.

Every year, thousands of Africans study, work, invest and build businesses beyond the countries of their birth. They contribute skills and experience that strengthens the communities they join while advancing a more connected Africa.

As someone born in Zimbabwe and now proudly calling Rwanda home, I have experienced this personally. Living and working in another African country has reinforced my belief that Africa’s greatest strength lies in its ability to learn from one another. Every African who crosses a border carries more than a passport. They carry experience, culture, ideas and relationships that enrich the communities they join.

This exchange of knowledge is one of Africa’s greatest competitive advantages. Innovation rarely develops in isolation. It grows when different experiences meet, when entrepreneurs learn from neighbouring markets, and when professionals bring new perspectives into organisations. Some of the continent’s most successful businesses have expanded beyond their home countries not simply by exporting products, but by sharing ideas, talent and expertise. The freer those exchanges become, the stronger Africa’s collective capacity to compete on the global stage.

The train in Masekela’s song carried miners, but it also carried hope. The train in Masekela’s song carried miners, but it also carried hope. Every passenger represented a family seeking opportunity, a community making sacrifices and a continent whose progress has always depended on the movement of its people.

As Africa continues to pursue greater economic integration, perhaps we should remember that connectivity is not a modern invention. It is part of our history. The challenge before us is not creating an interconnected continent from the beginning, but rediscovering one that has always existed beneath the borders we inherited.

The Africa Hugh Masekela sang about was not perfect, but it understood something timeless. Progress is rarely built in isolation. It is built when people, ideas and opportunity are allowed to travel.

Perhaps that is the Africa we should continue building today. One where borders define our countries but never limit our sense of belonging, collaboration, or shared ambition.
