...in 1290, two hundred years before the momentous expulsion from Spain, the entire Jewish community of England had been expelled and forbidden on pain of death to return. The act of expulsion, in the reign of Edward I, was unprecedented; England was the first nation in medieval Christendom to rid itself by law of its entire Jewish population. There was no precipitating crisis, as far as is known, no state of emergency, not even any public explanation. No jurist seems to have thought it necessary to justify the deportations; no chronicler bothered to record the official reasons. Perhaps no one, Jew or Christian, thought reasons needed to be given.
