With no POD before, say, 1660, have an independent state that...
---Is majority-Quaker.
---Exists until modern-day and maintains a Quaker majority.
---Follows the Quaker principals of peace, equality, toleration, and such.
It can be any size. The most likely paths: make Pennsylvania independent and keep it majority-Quaker somehow (or cut some independent state out of Pennsylvania), or have a Quaker-majority country in the British Isles.
