The word or phrase that best describes the political and religious atmosphere of the sixteenth and seventeenth centuries is "tumultuous" (D). During this period, the church was in a crisis.

The Reformation also moved the centre of power from the Roman Catholic Church to the German Lutheran church. Martin Luther was one of the leaders of the Reformation.
