More or less true actually... that's one of the reasons why so many moved there in the first place. We're talking late middle ages or so here. Which isn't to say that there was no antisemitism in Poland or anything like that.
Thirteenth century - it was actually illegal for Jews to live in England after that point right up until the Revolution.
It also depends what you mean by pogrom. Antisemitic riots weren't exactly
rare after the mid nineteenth century, though, yeah, massacres... last ones would be those sanctioned by Edward I.
