Collectively known as the "Anglo-Saxons", these are Angles and Saxons from what is now the Danish/German border area and Jutes from the Jutland peninsula.
The entire region is referred to as, "Hwicce" and settlements throughout the south are called Gewisse.
The Battle of Deorham is a critical battle that establishes the Anglo-Saxon rule in 577.
Saxon mercenaries have been present in Britain since before the late Roman period, but the main influx of population is thought to have taken place after the fifth century.
The precise nature of these invasions has not been fully determined, with doubts being cast on the legitimacy of historical accounts due to a lack of archaeological finds.
Gildas Sapiens’ De Excidio et Conquestu Britanniae, composed in the sixth century, states that when the Roman army departed the Isle of Britannia in the fourth century CE, the indigenous Britons were invaded by Picts, their neighbors to the north (now Scotland) and the Scots (now Ireland).
The Britons then invited the Saxons into the island, hoping to repel the invading armies of the north.
To their dismay, the Saxons themselves had turned against the Britons after vanquishing the Scots and Picts.
