This document provides an overview of ideas from the Enlightenment period that influenced the American founding fathers. It discusses philosophers like John Locke, Voltaire, and Rousseau who believed in natural rights like life, liberty, and property. It also discusses documents like the Magna Carta that limited the power of kings and established rights like fair trials. Preachers during the Great Awakening encouraged colonists to question authority and think for themselves, believing people could rule without a higher power like the king. These Enlightenment ideas and documents challenging absolute rule helped guide the founding fathers as they formed the U.S. Constitution.
