Liberal Christian vs. Conservative Christian

... unless you count the Uniterians who have remained a small liberal faith since the earliest days of Christianity...

After 1550 two organized religious groups sprouted with non-Trinitarian theology: 1) The Unitarian Church in Transylvania; 2) Minor Reform Church in Poland. It was at the Church in Transylvania that the term Unitarian originated from either its non-Trinitarian beliefs or the unity of the four-protestant churches there. By 1556 Transylvania was considered a Protestant country. King John Sigismund, who came to power in 1561, is the only known Unitarian King in history. Because of his faith he allowed freedom and tolerance of religion in the country. The official Decree of Religious Tolerance was passed in 1557. The religion debates that took place as a result were widely popular and the first one truly established the popularity of the Unitarian faith under the leadership of Francis David. By 1571 there were 500 of what we would now label Unitarian congregations. Unfortunately, the death of King John, also in 1571, lead to religious persecution once again and Francis David was imprisoned and died in jail.
