A new historical series presented by David Olusoga offers an in-depth exploration of Britain's involvement in the transatlantic slave trade, shedding light on aspects often overlooked or marginalized in traditional accounts of British history. Drawing on extensive academic research, including a register of slave traders compiled by a dedicated scholarly team, the series provides a detailed examination of key figures and institutions connected to the trade.

The series begins with a focus on John Hawkins’s expeditions to Africa during the 1560s. These voyages marked a significant moment as they challenged the Spanish and Portuguese dominance over transatlantic trade routes. Hawkins's ventures were supported by Queen Elizabeth I and her chief minister, William Cecil, illustrating the early endorsement of the slave trade at the highest levels of English governance.

Moving forward a century, the narrative shifts to the royal family’s involvement in the trade. Notably, the Duke of York—who later became King James II—played a role in managing the company granted control over the transatlantic slave trade, contributing to the royal finances during the reign of Charles II. This highlights the direct financial interests of the monarchy in the continuation and expansion of the slave trade during this period.

In addition to individual figures, the series emphasizes the participation of key institutions in financing and supporting the trade. Organizations such as the Royal Society and Lloyd’s of London are shown to have acted as investors, indicating that the economic networks underpinning the slave trade extended into prominent sectors of British society.

The series also begins with a prologue set in Bristol, a city historically linked with the slave trade, serving as a geographical and thematic starting point for the broader exploration.

By integrating academic findings with compelling narrative, Olusoga’s work contributes to a fuller understanding of the complexities of Britain’s imperial past, highlighting the intertwined roles of monarchy, commerce, and scientific institutions in the transatlantic slave trade. The series aims to provide viewers with a more comprehensive view of British history, challenging previous frameworks that have often downplayed or omitted these aspects.
