Andrew Roberts’s new book is The Last King of America: The Misunderstood Reign of George III, a biography of the monarch who led England during the American Revolution and who has been made into something of a caricature by Americans, most recently by his portrayal in the musical Hamilton as a preening, stuck-up (but funny) king of England. In this interview and in his book, Roberts goes to great lengths to deconstruct that distortion and, in the process, give us an extremely nuanced and detailed portrait of the man who created the conditions for America’s independence.
