recently, Andrew Spencer has agreed with Prestwich, arguing that Edward's reign "was indeed... a great one", and Caroline Burt states that "Edward I was without a doubt one of the greatest kings to rule England". Three major academic narratives of Edward have been produced during this period. F. M. Powicke's volumes, published in 1947 and 1953, forming the standard works on Edward for several decades, were largely positive in praising the achievements of his reign, and in particular his focus on justice and the law. In 1988, Michael Prestwich produced an authoritative biography of the King, focusing on his political career, still portraying him in sympathetic terms, but highlighting some of the consequences of his failed policies. Marc Morris's biography followed in 2008, drawing out more of the detail of Edward's personality, and generally taking a harsher view of his weaknesses and less pleasant characteristics, pointing out that modern analysts of Edward's reign denounce the King for his policies against the Jewish community in England. Considerable academic debate has taken place around the character of Edward's kingship, his political skills, and in particular his management of his earls, and the degree to which this was collaborative or repressive in nature. There is a great difference between English and Scottish historiography on King Edward. G. W. S. Barrow, in his biography of Robert the Bruce, accused Edward of ruthlessly exploiting the leaderless state of Scotland to obtain a feudal superiority over the kingdom followed by his determination to reduce it to nothing more than an English possession. Modern commentators have conflicting opinions on whether Edward's conquest of Wales was warranted. Contemporary English historians were firmly in favour of the King's campaigns there. Morris takes the position that the poor condition of Wales would have allowed for England to dominate it at some point or another, whether by direct conquest or through natural deterioration. Family First marriage By his first wife Eleanor of Castile, Edward had at least fourteen children, perhaps as many as sixteen. Of these, five daughters survived into adulthood, but only one son outlived his father, becoming King Edward II (1307–1327). Edward's children with Eleanor were: Katherine (1261 or 1263 – 1264) Joan (1265 – 1265) John (1266 – 1271) Henry (1268 – 1274) Eleanor (1269 – 1298) Unnamed daughter (1271 – 1271 or 1272) Joan (1272 – 1307) Alphonso (1273 – 1284) Margaret (1275 – 1333) Berengaria (1276
