However, modern analysis of Offa's Dyke suggests that it was built in the 5th century, well before the reign of King Offa.

^Sansom, p. 90; excerpt, "... Nakamaro, better known by his later title as the prime minister Oshikatsu, was in high favour with the emperor Junnin but not with the ex-empress Kōken. In a civil disturbance that took place in 764–765, Oshikatsu was captured and killed, while the young emperor was deposed and exiled in 765 and presumably strangled. Kōken reascended the throne as the empress Shōtoku, and her priest Dōkyō was all powerful until she died withous issue in 770."
