The Historia Regum Britanniae, or History of the Kings of Britain, was written in around 1136 by Geoffrey of Monmouth and purports to tell the story of the kings of Britain from the settlement of the island by the Trojan Brutus, grandson of Aeneas, through to the seventh century when the Anglo-Saxons had taken control of much of Britain. History of the Kings of Britain was highly popular during the Middle Ages and copies spread across the whole of western Europe, with over 200 manuscripts surviving from the period. It went on to influence texts into the sixteenth century and was one of the first to weave together the legend of King Arthur as well as the stories of King Lear and Cymbeline, both later immortalised by Shakespeare.
