The judges had over 200 international entries but felt Rae's work had “stylish prose, clarity of argument, a deep level of research and originality of thought.” Rae is one of 15 winners who are invited to attend Peterhouse College for a prize giving later this month.
Rae said: “I am just so happy to have won, I can hardly believe it.”
Elle Wheatly, History lecturer at Penwith College, said: “Rae worked exceptionally hard on an ostensibly obscure topic - The history of humanitarianism intervention - and managed to make her work a rigorous survey through time that maintained conceptual complexity. She worked independently and with determination. We are thrilled to see Rae’s original thinking acknowledged in this way.”
