In his new book, Chain of Ideas, professor Ibram X Kendi offers a meticulous analysis of the so-called 'great replacement theory', providing a framework for understanding modern political turmoil. The central thesis is that this ideology, which claims elites are enabling people of colour to displace white populations, underpins what Kendi terms 'our authoritarian age'.
Kendi argues that great replacement theory is not merely white nationalism, but a transnational movement. Since Donald Trump's 2016 election, its proponents have shifted from domestic to international organising, making the label 'white nationalist' insufficient to capture their evolving identity and ideology.
The theory's power lies in its interconnected ideas: that racism against people of colour is over, that anti-white racism is rising, and that insurrections protect the nation. Individually weak, these ideas gain emotional resonance when linked, forming a 'chain' borrowed from 18th-century French lawyer Joseph Michel Antoine Servan.
Kendi highlights a paradox: many right-wing parties are led by people from marginalised backgrounds, such as Reform UK's Zia Yusuf or Conservative leader Kemi Badenoch. He argues this is a deliberate strategy—'proximity denial'—to launder bigotry and present the theory as respectable, as seen with Germany's AfD successfully challenging its 'extremist' label.
The book traces the theory's origins to southern France and examines how far-right leaders seek to replace historical narratives with their own. Kendi, a target of the right since his 2019 bestseller How to Be an Antiracist, offers a comprehensive look at a conspiracy theory that continues to shape global politics.
