American Romanticism and Transcendentalism emerged in the early 19th century, emphasizing individualism, nature, and spiritual enlightenment. These movements celebrated personal freedom, rejected societal norms, and viewed nature as a source of divine inspiration. Key figures like Emerson, Thoreau, and Whitman shaped this era, exploring themes of self-reliance and interconnectedness. Their works continue to influence American culture, inspiring environmental stewardship, social reform, and the pursuit of authenticity in modern life.
