Describe the cause of the Enlightenment in three to five sentences ?

The Enlightenment was a period of deep scientific thought throughout Western Europe which brought many (mainly philosophers) to begin questioning authority and how they were ruled. Many common citizens were uneducated and unable to educate themselves due to their illiteracy. Instead, they simply followed those who were educated (the church, government) and allowed them to use this to any means. Philosophers such as Martin Luther and Isaac Newton, fed up with the lies being fed to the people, began printing bibles into a variety of languages, encouraging education, and creating experiments to debunk church claims. Due to this rise in learning and enlightenment, more books and publications were being made, and more people began talking and sharing their new ideas.

It would be the "Stamp Act Congress" that was formed first, since this was one of the first major meetings of representatives from different colonies that had the goal of addressing the new taxes imposed by the British Parliament.
