Reading edition
Ecgberht’s titles commonly run, “Rex,” “Regali fretus dignitate,” “Occidentalium Saxonum rex,” once, in 820, “Rex Occidentalium Saxonum necnon et Cantuariorum” (Kemble, Cod. Dipl. i. 289), but in one charter of 828 (Cod. Dipl. i. 287) he appears as “Ecgberhtus gratiâ Dei Rex Anglorum.” In that year he had granted out Mercia to an Under-king and had reduced all the Welsh to submission.
