In the first lecture, Dr. Biggar introduces the necessity to explain and critically examine the concept of decolonization in a nuanced way. He argues that the decolonization movement is largely misguided, resting on falsehoods about both the present and the past, particularly regarding the history of European countries with overseas empires. The lecture emphasizes the importance of this topic, as the cultural revolutionary form of decolonization threatens to undermine faith in the liberal West at a time of increasing threats from illiberal states.

In lecture two, we delve into the complex history of slavery within the context of the British Empire, examining its ancient roots, universal prevalence, and the moral and economic factors that led to its eventual abolition. The lecture highlights the significant role played by Christian thought and popular campaigns in driving the abolitionist movement, while also acknowledging the political compromises and economic considerations that shaped the process of emancipation.

In lecture three, Dr. Biggar delves into the complex topic of racism within the context of the British Empire, examining various historical examples and drawing nuanced distinctions between racism, patronizing attitudes, and cultural aloofness. The lecture emphasizes that, while the British Empire did contain instances of racial prejudice and discrimination, it cannot be fairly characterized as centrally or essentially racist, as it also demonstrated respect, admiration, and genuine benevolence toward native peoples, driven by a conviction in the basic human equality of all races.
