Al Andalus, the name the Muslims gave Iberia was chosen because they confused the Visigoths with the Vandals
Where did the Vandals come from?
Like the Goths, the Vandals may have originated in Scandinavia before migrating south. They first breached the Roman frontier in 406, with the Roman Empire distracted by internal divisions, and began clashing with both Visigoths and Romans in Gaul and Iberia.
What happened to the Vandals?
In the words of historian Roger Collins: "The remaining Vandals were then shipped back to Constantinople to be absorbed into the imperial army. As a distinct ethnic unit they disappeared". Some of the few Vandals remained at North Africa while more migrated back to Spain.
