That said, if you want to be able to figure out what led to various schisms in any detail, you're probably better off with Dyck (n.b. you _still_ won't understand, but at least some clues will be present, however distorted).
Should you _want_ to read a Mennonite history? Well, I did, because one of my grandparents was ethnically Mennonite in Canada (ancestors in the Kleine Gemeinde) and I have a bunch of living relatives who are active members of Mennonite churches (altho I infinitely prefer the cousin-once-removed who is under the ban and his wife, who really _enjoys_ putting on a big spread when we go visit and all the church-y types show up to see us but will refuse to eat her cooking because of the ban. You really have to eat her pie and see the looks on their faces when they feel compelled to say no to truly, truly, truly understand how much fun you can have with other people's judgmentalism). The ancestry aspect pushed me very hard in the direction of understanding the history; knowing actual Mennonites and feeling the similarities between them and JWs made it really hard to proceed. I can't tell whether there's any innate value in reading this book, independent of my personal circumstances. I found it worthwhile, altho if I want to reread it, I'll get a more current edition.
Next on the list of the Amish history which shares one author with the Fire/Water book. I feel more optimistic about that, altho strictly speaking I'm also in the middle of Klassen's _Mennonites in Early Modern Poland and and Prussia_ (kindle edition). Realistically, I'll probably read something trashy with lots of sex and violence to try to clear my mental palate.
I did pick up a great new term/TLA: HPC, described here:
