Æthelwulf's reputation among historians was poor in the twentieth century. In 1935, the historian R. H. Hodgkin attributed his pilgrimage to Rome to "the unpractical piety which had led him to desert his kingdom at a time of great danger", and described his marriage to Judith as "the folly of a man senile before his time". To Stenton in the 1960s he was "a religious and unambitious man, for whom engagement in war and politics was an unwelcome consequence of rank". One dissenter was Finberg, who in 1964 described him as "a king whose valour in war and princely munificence recalled the figures of the heroic age", but in 1979 Enright said: "More than anything else he appears to have been an impractical religious enthusiast." Early medieval writers, especially Asser, emphasise his religiosity and his preference for consensus, seen in the concessions made to avert a civil war on his return from Rome. In Story's view "his legacy has been clouded by accusations of excessive piety which (to modern sensibilities at least) has seemed at odds with the demands of early medieval kingship". In 839 an unnamed Anglo-Saxon king wrote to the Holy Roman Emperor Louis the Pious asking for permission to travel through his territory on the way to Rome, and relating an English priest's dream which foretold disaster unless Christians abandoned their sins. This is now believed to have been an unrealised project of Egbert at the end of his life, but it was formerly attributed to Æthelwulf, and seen as exhibiting what Story calls his reputation for "dramatic piety", and irresponsibility for planning to abandon his kingdom at the beginning of his reign.
