You have to read the folks who were anti-Semitic and the periods in which they lived to understand it. Not modern sources that present comic book explanations, but the actual texts written at the time to understand how such occured. Further to understand why particular hate arose, you must understand why folks saw Jews as threats, which you will not get unless you read both sides of the conflict and try to look at the world they way they did, rather than the modern American mind set.
Oddly enough once you see the pattern once, you will see the same pattern repeat again and again throughout history, though the exact timeline and final outcome varies somewhat.
Three easily researched periods and one less easy but given the current middle east situation worth understanding.:
Northern Germany 1638 to 1945 (special attention to 1916 to 1945):
England 1066 to 1290 (special attention paid to 1215 to 1290)
Poland 1085 to 1795, there are actually many cycles in that time, each one getting worse for the Jews but very instructive, as golden ages such as 1264 to 1295, 1332 to 1349 and 1385 to 1407 alternated with periods of repression due to various reasons.
Persia: 722 BC to 323 BC (special attention to 530 to 432 BC) The Persian sources are hard to find in English, but if you try hard enough you can find them on the net.
I did a little research based on your recommendations and I think I understand the origin of the hatred a little better.
Basically it mostly stims from usury.
And the poor Jews got a two fer from it.
The church taught that usury was sinful from the pews, and it’s fairly normal to resent those you owe money too.
Since Jews were the only group basically allow to charge interest they got despised by both groups. Plus killing the person you owe money or driving them out of town, ect has the benefit of wiping out your debt!
It’s no wonder in hindsight why the Jews have been so singled out for hatred as compared to other groups.
Thanks for the information.
