Æthelred's status is unclear, and this is reflected in the varying titles given to him by different historians. He is sometimes called "ealdorman", but also "Lord of the Mercians" and "subking". Coinage issued in English Mercia in Ceolred's time named him as king, but in Æthelred's time it named the West Saxon king, yet Æthelred issued some charters in his own name, implying royal authority. West Saxon sources refer to him as an ealdorman, emphasising Mercian subordination to the West Saxon monarchy, whereas Mercian ones describe him as Lord of the Mercians, and Celtic ones sometimes as King of Mercia. The late tenth-century chronicler Æthelweard, in his annal for 893, called Æthelred "King of the Mercians", but recorded his death in 911 as that of the "Lord of the Mercians".
