This position of dominance was short-lived, as Wiglaf returned and restored Mercian independence in 830, but the expansion of Wessex across south-eastern England proved permanent.
See domineeriv seisund oli lühiealine, kui Wiglaf tuli tagasi ja taastas aastal 830 Mercia iseseisvuse, kuid Wessexi laienemine üle Kagu-Inglismaa jäi püsima.
