Juliet Barker is a British historian and biographer whose work concentrates on medieval England and nineteenth-century literary history. Trained as a medievalist, she wrote her doctoral thesis on the history of the English tournament and later worked as librarian and curator at the Brontë Parsonage Museum in Haworth. That experience gave her access to extensive unpublished Brontë manuscripts and helped shape her career as a biographer. Barker is known for combining close archival research with strongly narrative history, often reconstructing not only major events but also the lives of lesser-known participants. Her major books typically take several years of research, and she has written extensively for radio, television and the press as well as publishing works of history and biography.
Her books range from literary biography to medieval political and military history. The Brontës is a large-scale collective biography of Charlotte, Emily, Anne, Branwell and their family, while Wordsworth: A Life examines the poet William Wordsworth and his circle. Her medieval works include The Tournament in England, 1100–1400 and Agincourt: The King, the Campaign, the Battle, a detailed reconstruction of Henry V’s 1415 campaign. Conquest: The English Kingdom of France 1417–1450 continues the story through the later stages of the Hundred Years’ War, including the rise of Joan of Arc and the eventual collapse of English rule in France. England, Arise examines the Great Revolt of 1381, using court and legal records to recover the experiences and objectives of ordinary rebels as well as the actions of Richard II and his government.
