William Stubbs (1825-1901), one of the leading historians of his generation, pursued his academic research alongside his work as a clergyman. He was elected Regius Professor of Modern History at Oxford in 1866 and appointed a bishop in 1884. Stubbs was a foundational figure in medieval English history, with a special interest in the twelfth and thirteenth centuries. The three-volume study reissued here, originally published between 1874 and 1878, was one of his most influential works. Nine editions appeared during his lifetime and it was prescribed reading for generations of students. It traces the evolution of English political institutions from the early Anglo-Saxon invasions of Britain to 1485, relying mainly on primary sources. Volume 1, published in 1874, begins with evidence for Germanic administrative systems during the Roman period, and then focuses on the Anglo-Saxon era and the Norman period, ending with the reign of Henry II.
