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 The earliest concrete historical references to Jews in Scotland are from the late 17th century.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.
Bar Kokhba revolt The Bar Kokhba revolt (Hebrew: מרד בר כוכבא‎ ; "Mered Bar Kokhba") was a rebellion of the Jews of the Roman province of Judea, led by Simon bar Kokhba, against the Roman Empire. Fought circa 132–136 CE, it was the last of three major Jewish–Roman wars, so it is also known as The Third Jewish–Roman War or The Third Jewish Revolt. Some historians also refer to it as the Second Revolt of Judea, not counting the Kitos War (115–117 CE), which had only marginally been fought in Judea.
