In this lesson from Unit 2: Colonial America, students examine the Enlightenment and the major thinkers whose ideas helped shape the foundations of the United States government and political system. Students explore how Enlightenment philosophers challenged traditional ideas about monarchy, government authority, religion, and individual rights during the 1600s and 1700s.

The lesson begins with the concept of unalienable rights, or natural rights that people possess at birth rather than rights granted by government. Students analyze how these ideas later influenced the Declaration of Independence, including the famous phrase “Life, Liberty, and the Pursuit of Happiness.”

Students then study the broader Enlightenment movement and learn how thinkers across Europe encouraged the use of reason, logic, education, and critical thinking to question traditional authority and improve society.

A major focus of the lesson is John Locke and his theory of the social contract. Students examine Locke’s belief that governments exist through the consent of the governed, that government power should be limited, and that citizens have the right to change or overthrow governments that fail to protect their rights. The lesson also explores Locke’s ideas about natural rights and separation of governmental powers.

The lesson also introduces Charles de Montesquieu and his expansion of Locke’s ideas through the concept of separation of powers into legislative, executive, and judicial branches. Students analyze how Montesquieu’s ideas later influenced the structure of the United States government.

Students then examine William Blackstone and his influence on English common law, religious tolerance, natural rights, and legal traditions that later shaped American law and constitutional thinking.

The lesson also revisits Thomas Hooker and William Penn, connecting their colonial leadership to Enlightenment principles such as representative government, religious freedom, elections, and government by consent.

By the end of the lesson, students will understand how Enlightenment thinkers influenced colonial ideas about liberty, government, rights, democracy, and constitutional principles that later became central to the founding of the United States.
