Exactly, there's no evidence of systemic antisemitism.
1517 - Events arising from a regime collapse no religious element, not pogroms
1679 - Yes a barbaric act, but there was a context and wasn't antisemtism.
1834 - Yes more killings but again there was a context, suspcions of Jews aligning with Egypt.
1838 - Yes, local skirmishes during a rebellion not antisemitism
1849 - Yes a good example of Christian antisemitism, the "blood libel" a new phenomenon.
1834 - Morocco, yes anti Jewish violence durig rebellions, again local political tensions.
These were local events, not evidence of endemic Jew hatred.
