The Second Great Awakening led to the rise of evangelicalism in America and spread revivalism and emotional religion through large camp meetings on the frontier. This sparked reform movements in the North led by figures like Charles Finney who sought to end sins like alcohol abuse. Revivalism encouraged new ideas about domesticity, childhood, and institutions. Some reforms like abolitionism and women's rights became more radical over time, splitting moderates from perfectionists. Transcendentalism emerged as a protest movement focusing on intuition over doctrine. Utopian communities like Brook Farm and Oneida experimented with new social and economic structures based on cooperation and equality. However, reform was not without critics and prompted counterarguments.
