When did revivalism begin?

Revivalism began in the early 18th century, particularly with the First Great Awakening in the American colonies around the 1730s and 1740s. This movement emphasized personal faith, emotional expression, and a direct relationship with God, often characterized by itinerant preaching. It sought to renew and invigorate religious practices and beliefs, leading to significant growth in various denominations. Subsequent revival movements continued throughout the 19th and early 20th centuries, further shaping American religious life.
