Regarding Danbury Baptists and their letter to the federal government seeking redress.
CT (my home for almost 70 years) like most of New England was settled by the Puritans (Congregational Churches). Each village had a parish and the minister served as head of government and tax collector. This continued to the middle of the 1800s, long after the USA was a country and the US Constitution in force.
My small town has 4 distinct neighborhoods, each was a parish and still has an active Congregational Church bearing the name.
Until the early 1900s, any religious institution wanting to operate in CT had to get a Charter from the State of Connecticut. My shul received its charter in 1881. My FIL is buried in a local Jewish cemetery that received its charter in 1918.
This issuing of charters (and requirement thereof) established State approved religions in direct violation of the First Amendment.
BTW, males who wished to vote in the State of CT before approx 1850 had to be members of the Congregational Church in their Parish and current with tax obligations. Another violation of the First Amendment.
