James II of England and VII of Scotland. He thought that, if there was going to be an end to discrimination against Catholics, which naturally, as a Catholic he wanted, it had to be accompanied by an end to the parallel discrimination against Protestant dissenters and others.

Hence the Declaration of Indulgence in 1687, which

1. suspended all penal laws in matters ecclesiastical for not attending the established Church of England or not receiving communion according to its rites;
2. permitted people to worship other than in the established Church of England either in private houses or in chapels;
3. ended the requirement that people take various religious oaths before advancement to civil or military office.

The declaration applied to Catholics, Protestants, Unitarians, Jews, Muslims, and people of any or even no faith.

Of course this didn't go down with people who wanted discrimination to continue. Clearly this kind of madness could not be allowed to continue, and once King James had been driven out, it was brought back. Moe especially forcibly and ferociously, of course, in Ireland.
