Withdrawal of all Roman forces and many societal leaders completed in about the year 410 and leading families of the Dobunni tribe may have regained power within the now Roman-influenced, interconnected and intermixed Celtic Brythonic local people.
This intermix is reflected by the fact a large minority of basic words and available synonyms in Welsh have a Latin base.
 In the Anglo-Saxon Chronicle Gloucester is shown as part of Wessex from the Battle of Deorham in 577.
At some point afterwards, along with the rest of its shire excluding the Forest of Dean, Gloucester was part of the minor kingdom of the Hwicce.
In 628, as a result of the Battle of Cirencester, that kingdom became a client or sub-kingdom of Mercia.
From about 780, the Hwicce was no longer feigning any pretense as a kingdom and became part of Mercia.
Mercia, allied by matrimony and sharing a desire to counter the Danish onslaught as had conquered swathes of the wider island at large, submitted to Alfred the Great's Kingdom of Wessex in about 877–883.
A 20th century writer intuitively adds that Roman stem Gleu- Glev- was, doubtless, pronounced without any final consonant.
Claudia Castra is mentioned in the 18th century as a possible Latin name related to the city.

The first bridging point on a navigable, defensive barrier, great river and the foundation in 681 of the abbey of St Peter by Æthelred of Mercia, favoured town growth; and before the Norman conquest of England, Gloucester was a borough governed by a portreeve, with a castle which was frequently a royal residence, and a mint.
In the early 10th century the remains of Saint Oswald were brought to a small church here and shrine built there, a draw for pilgrims.
The core street layout is thought to date to the reign of Æthelflæd in late Saxon times.

In 1051 Edward the Confessor held court at Gloucester and was threatened there by an army led by Godwin, Earl of Wessex, but the incident resulted in a standoff rather than a battle.
