They along with Angles, Frisian and Saxons settled in England after the departure of the Roman Army from Britain in the fifth-century AD, and eventually became known as Anglo-Saxon.
These tribes were among the barbarians who overran the Roman Empire which began the Early Middle Ages in Europe.
The Jutes were the earliest of the Saxon tribes who established themselves in Britain. Between the eyras 449-586, the Saxon Octarchy, comprising one Jutish, three Saxon and four Angle kingdoms was established in Britain.
The Jutes, first mentioned by Tacitus in his ‘Germania’ as the Eudoses, appear to have originally been a Samartian tribe from Southern Russia who migrated to Denmark and settled in the Cymbric Peninsula between Zuyder Zee and the Northern tip of the peninsula, giving it their name.
After the Roman army left the British Isles, riders and pirates from Ireland began to raid the coastal towns of Britain. The worst of these raiders were the Picts and Scots.
The unhappy Britons asked the Saxons, along with Angles and Jutes to defend against the Picts and Scots. In 449 AD the first Jutes to arrive, Hengist and Horsa, sons of one Wihtgils, reported landed at Ebbsfleet on the Isle of Thanet with followers and started to drive out the Picts and Scots.
The people of Kent and the inhabitants of the Isle of Wight are the Jutish origin and also those opposite the Isle of Wight, that part do the kingdom of Wessex which is till today called the nation of the Jutes.
The Jutes, Angels, Frisian and Saxons collectively became known as the Anglo-Saxons as early as the seventh century.
Those Jutes in Jutland who did not migrate were later absorbed by the Vikings, who established the kingdom of Denmark, comprising most of the Jutland Peninsula.
