Input: Question: Why was there a division between the crown and nobility? Passage:Originally a legendary chronicle written in Anglo-Norman in the thirteenth century (identified by the fact that some existing copies finish in 1272), the Brut described the settling of England by Brutus of Troy, son of Aeneas, and the reign of the Welsh Cadwalader. In this, it was itself based on Geoffrey of Monmouth's text from the previous century. It also covered the reigns of many kings later the subject of legend, including King Cole, King Leir (the subject of Shakespeare's play, King Lear), and King Arthur, and exists in both abridged and long versions. Early versions describe the country as being divided, both culturally and politically, by the River Humber, with the southern half described as "this side of the Humber" and "the better part". Having been written at a time of division between crown and nobility, it was "baronial in its sympathies". It was probably originally composed "at least in part" by clerks in the Royal chancery, although not as an official history. It later became a source for monastic chronicles. Popular already in its early incarnations, it may even have limited the circulation of rival contemporary histories.
