In 1826 conducted the first revival a large religious meeting held outdoors?

The first large outdoor religious meeting, often referred to as a revival, was held in 1826 by Charles Grandison Finney in the United States. This event marked a significant moment in the Second Great Awakening, a period of religious fervor and revivalism. Finney's approach emphasized emotional appeal and personal conversion, attracting large crowds and transforming the landscape of American evangelicalism. His meetings laid the groundwork for future revivals and outdoor gatherings in the 19th century.
