Archaeology has evolved: Four eras of understanding Africa’s past

Archaeology has evolved significantly over its history, undergoing four distinct eras that shaped how we understand Africa's past. In the early years, archaeological work was primarily based on collections with little analysis, carried out by non-specialists such as museum employees, missionaries, administrators, and travelers. As the discipline progressed, the 20th century saw a shift towards more robust analytical approaches, although colonial misperceptions of Africa's history still dominated.

The second world war brought about technological advancements, with methods like radiocarbon dating emerging and fundamentally changing archaeological approaches. An early example of this was Bernard Fagg's work in Nigeria on the Jos Plateau, where he dated terracotta heads over 2,000 years old, contradicting colonial views of complex civilizations emerging later in the region.

The diaspora of archaeology began in the 1960s, with communities playing a crucial role in research as either workers or providers of information and knowledge. This marked a significant shift in archaeological frameworks, granting agency to Africans.

Today, archaeology plays a vital role in modern Africa, helping to shape the world we inhabit through history, trade, interaction, colonization, slavery, and conflict. It has the potential to promote social harmony, improve mental health, create sustainable jobs, and foster local and indigenous ways of doing and knowing. However, issues such as looting, conflict, and climate change pose significant threats to Africa's heritage, making preservation an essential task for archaeologists and historians.

Moving forward, the field of archaeology must address the power imbalance in collaborations, emphasizing the growth of local capacity and ensuring a more equitable distribution of resources and knowledge.
