The Jutes migrated to Great Britain eventually, some as mercenaries by Brythonic King Vortigern, and were granted the south-eastern territories of Kent, the Isle of Wight and other areas, where they settled.
They were later absorbed or ethnically cleansed by the invading Angles and Saxons, who formed the Anglo-Saxons.
The remaining Jutish population in Jutland assimilated in with the settling Danes.
A short note about the Dani in "Getica" by the historian Jordanes is believed to be an early mention of the Danes, one of the ethnic groups from whom modern Danes are descended.
In the early 11th century, Canute the Great won and united Denmark, England, and Norway for almost 30 years with a Scandinavian army.
