Check out "The Kidnapping of Edgardo Mortara". I first heard about this case when I was a kid reading Jewish themed comic books. It was a big time international publicity case circa 1860 and was a factor, though I'm not sure how significant a factor, in the Vatican losing political control over the Papal States. I would call it child abuse, though not the usual kind considered today. Absolutely fascinating. It also had repercussions within Jewish communities in the United States.
