In my course The History of History, the students do research on the Pulitzers in History and Biography. One consistent result is an increase of books on Black history, while the authors' ethnicity remains the same.
The winner and the runners up of the 2024 Pulitzer Prize for History are about Black history. All three authors are White. The Pulitzer for Biography shared between two books on Black history. One author is White, one Asian-American.
