In 1662, the Quaker Act was passed in England and Wales. One of the clauses of this act made it treasonable not to swear an oath of allegiance to the king.

This was used by their enemies to imprison Quakers and steal their possessions, as Quakers didn't swear oaths.

They still don't. I'm English and a Quaker. How do you think I, or my children might feel about this bit of stupidity?
