The Age of Enlightenment: key ideas

Welcome to World History: Revolutions and Nation-States! This lesson focuses on the age of enlightenment: key ideas. Analyzing social systems and historical patterns informs our understanding of contemporary issues.

The Age of Enlightenment (17th–18th centuries) emphasized reason, science, and individual rights, challenging traditional authority. Key thinkers: Locke (natural rights, consent of governed), Montesquieu (separation of powers), Rousseau (social contract), Voltaire (religious tolerance, free speech). These ideas directly inspired the American and French Revolutions. The Industrial Revolution (1760s–1840s, beginning in Britain) transformed production from hand crafts to machine manufacturing, created factory systems, urbanization, a new working class, and capitalism's expansion. The 19th century saw nationalism (the desire of ethnic groups for self-determination) reshape European and world politics. New Imperialism (1870–1914): European powers colonized most of Africa and Asia, driven by economic interests, nationalism, and Social Darwinism. Colonialism imposed European languages, religions, and political structures, while extracting resources—legacies still felt today.

As you engage with this material, consider both the theoretical foundations and practical applications. Think critically about how this concept builds on prior knowledge and where you might apply it beyond the classroom.

Challenge yourself to go beyond memorization—seek to understand the "why" behind the processes and principles.
