Haverfield was the first to undertake a scientific study of Roman Britain and he is considered by some to be the first theorist to tackle the issue of the Romanization of the Roman Empire. Some consider him the innovator of the discipline of Romano-British archaeology. His works include The Romanization of Roman Britain (1905),Ancient Town Planning (1913), and The Roman Occupation of Britain (1924), many monographs, and the authoritative chapters he contributed to the Victoria History of the Counties of England. He excavated the Roman fort at Hardknott, the site of ancient Mediobogdum in Cumbria. He collected and published known Latin inscriptions in Britain.
Among his students was the archaeologist and topographer Thomas Ashby (1874–1931), the first scholar and third director of the British School at Rome, the Oxford historian, archaeologist, and philosopher R. G. Collingwood (1889–1943) as well as John Garstang (1876-1956), archaeologist and anthropologist (J. Garstang, 1950).
