<racism and xenophobia in 18c Britain>
well the influx of east european jews certainly stirred up a lot of anti-semiticism; synagogues burned etc
I seem to recall there was an attempt to frame the jews for the Jack the Ripper killings:
from wiki:
<rumours had been circulating that the killings were the work of a Jew dubbed "Leather Apron", which had resulted in antisemitic demonstrations. ... with the strong feeling against the Jews that already existed, the message might have become the means of causing a riot:
" my attention was called to some writing on the wall of the entrance to some dwellings at No. 108 Goulston Street, Whitechapel which consisted of the following words: "The Juews are not [the word 'not' being deleted] the men that will not be blamed for nothing", ... strong feeling existed against the Jews generally, and as the Building upon which the writing was found was situated in the midst of a locality inhabited principally by that Sect, I was apprehensive that if the writing were left it would be the means of causing a riot"
Religious tensions were already high, and there had already been many near-riots.>>
