Under which Roman Emperor's effective conquest of Britain was it possible that Jews visited Scotland?
History of the Jews in Scotland The earliest date at which Jews arrived in Scotland is not known. It is possible that Jews visited Scotland at the time of the Roman Empire's conquest of southern Britain, but there are no records of this. The earliest concrete historical references to Jews in Scotland are from the late 17th century. The vast majority of Scottish Jews today are Ashkenazi who mainly settled in Edinburgh, then in Glasgow in the mid 19th century. Most histories of Jews in Scotland deal with the subject from a British perspective, thus tending to marginalise any distinctly Scottish dimension.
Constantine the Great Constantine the Great (Latin: "Flavius Valerius Aurelius Constantinus Augustus" ; Greek: Κωνσταντῖνος ὁ Μέγας ; 27 February 272 AD – 22 May 337 AD), also known as Constantine I or Saint Constantine (in the Orthodox Church as Saint Constantine the Great, Equal-to-the-Apostles), was a Roman Emperor of Illyrian-Greek origin from 306 to 337 AD. He was the son of Flavius Valerius Constantius, a Roman Army officer, and his consort Helena. His father became "Caesar", the deputy emperor in the west, in 293 AD. Constantine was sent east, where he rose through the ranks to become a military tribune under Emperors Diocletian and Galerius. In 305, Constantius raised himself to the rank of "Augustus", senior western emperor, and Constantine was recalled west to campaign under his father in Britannia (Britain). Constantine was acclaimed as emperor by the army at Eboracum (modern-day York) after his father's death in 306 AD, and he emerged victorious in a series of civil wars against Emperors Maxentius and Licinius to become sole ruler of both west and east by 324 AD.
