The legend of King Arthur begins in the early Middle Ages. In this period England was not yet considered a country, it was known as the kingdom of the Britons.
This kingdom was constantly attacked by invading Saxons, Angles and together, Germanic tribes from southern Scandinavia.
Tradition has it that King Arthur was responsible for stopping the constant invaders from entering south-west Britain, and thus took it upon himself to be the defender and protector of the Britons from their enemies.
Thanks to Arthur’s bravery and battle-winning skills, Britain continued to belong to the Britons for some time.
