Where can I read about the debates around religious freedom in England? I feel like that spans too broad of an area. I'm interested in the act of toleration, atheists, and heresy. The questions I'm wondering about are "When did England stop trying to enforce one religion? What arguments were used against religious freedom? When did people stop torturing heretics? What arguments were used for or against it? When did atheists start becoming tolerated?" I'm really interested in the intellectual history side of it. I've been told enforcing one religion stopped when Charles II became king but I'm not sure.
It shows its age in places now but Christopher Hill's World Turned Upside Down is still a good guide to religious dissent during the English Civil War. It's very readable, though it doesn't shy away from the technical details if that's what you're into.
On a factual point, religious absolutism did not end with Charles II. Catholics were not granted equal political rights until 1829. Jewish emancipation wasn't won until 1858. If you're interested in this particular debate I'd recommend reading Thomas Macaulay's speech to House of Commons on the question: https://mises.org/library/civil-disabilities-jews-britain
