The Enlightenment was a period of the rule of the scientific method, it was a moment when the Church lost influence over the academia and the importance of philosophers such as Voltaire, John Locke, Thomas Hobbes, David Hume, Rousseau, Adam Smith, and others.

By then Germany already had a 300,000 man army and over 2,000 war planes, with plans for additional buildup.
