Question

How did secularism and individualism ideas of the enlightenment affect later governments?

Answer 1

Second, the religion and the Church. The Enlightenment philosophers began to contest the dogma of the Catholic Church, which considered earthly life to be a simple passage towards eternal life. They challenged the teaching of the priests, divine revelation and Church traditions. The existence of one God, Creator of the Universe, was accepted, but His intervention in the history of humanity was rejected. “Creation submits only to the laws of nature” - is the concept known as ‘deism’.

Idea that not one religion could hold the true answer of god's existence, and people shouldn't be forced to a certain religion by the government came through this.

Later the U.S and other western countries would model their countries with separation of the church from the state entirely.
