Anglo-Saxons probably conquered Kent before Mons Badonicus. There is both documentary and archaeological evidence that Kent was primarily colonised by Jutes, from the southern part of the Jutland peninsula. According to legend, the brothers Hengist and Horsa landed in 449 as mercenaries for a British king, Vortigern. After a rebellion over pay and Horsa's death in battle, Hengist established the Kingdom of Kent. Some historians now think the underlying story of a rebelling mercenary force may be accurate; most now date the founding of the kingdom of Kent to the middle of the fifth-century, which is consistent with the legend. This early date, only a few decades after the departure of the Romans, also suggests that more of Roman civilization may have survived into Anglo-Saxon rule in Kent than in other areas.
