Historians have seen Ealdred as an "old-fashioned prince-bishop". Others say he "raised the see of York from its former rustic state". He was known for his generosity and for his diplomatic and administrative abilities. After the Conquest, Ealdred provided a degree of continuity between the pre- and post-Conquest worlds. One modern historian feels it was Ealdred who was behind the compilation of the D version of the "Anglo-Saxon Chronicle", and gives a date in the 1050s as its composition. Certainly, Ealdred is one of the leading figures in the work, and it is likely one of his clerks compiled the version.
