This September Manchester University Press published a volume of essays, Global White Nationalism: From Apartheid to Trump which I edited along with Camilla Schofield and Jennie Sutton.
The book emerged from a collaborative project motivated by the desire to explain the connected triumphs of Trump and the Brexit referendum. It reveals that far from provincial holdovers from a distant past, white nationalists throughout the English-speaking world have been adaptable and formed connections across the globe.
You can read an excerpt from the book introduction at the Boston Review.
I have written short pieces for the Washington Post and Irish Times (twice) based on my research for this book.
