Under which Roman Emperor's effective conquest of Britain was it possible that Jews visited Scotland?
Roman conquest of Britain The Roman conquest of Britain was a gradual process, beginning effectively in AD 43 under Emperor Claudius, whose general Aulus Plautius served as first governor of Roman Britain (Latin: "Britannia" ). Great Britain had already frequently been the target of invasions, planned and actual, by forces of the Roman Republic and Roman Empire. In common with other regions on the edge of the empire, Britain had enjoyed diplomatic and trading links with the Romans in the century since Julius Caesar's expeditions in 55 and 54 BC, and Roman economic and cultural influence was a significant part of the British late pre-Roman Iron Age, especially in the south.
Riothamus Riothamus (also spelled Riutimus or Riotimus) was a Romano-British military leader, who was active circa AD 470. He fought against the Goths in alliance with the declining Roman Empire. He is called "King of the Britons" by the 6th-century historian Jordanes, but the extent of his realm is unclear. Riothamus is a Latinization of the Brythonic personal name "*Rigotamos", meaning 'king-most', 'supreme king' or 'highest king'. Though it is still a matter of debate, several scholars consider his life to have been one of the possible sources for the King Arthur legend.
