The Great Awakenings were periods of rapid and dramatic religious revival in American religious history, from the 1730s to the mid-19th century. In result, a multitude of diverse Protestant denominations emerged. In the First Great Awakening, John Wesley founded Methodism which in turn sparked Evangelicalism. The Second Great Awakening brought Adventism, the Holiness movement and Plymouth Brethren alongside other denominations. The Salvation Army was founded during the Third Great Awakening. Some scholars propose the Fourth Great Awakening took place in the late 20th century. Modernist and liberal streams shaped mainline denominations during the Age of Enlightenment.
