The Second Great Awakening was a Protestant religious revival during the late 18th to early 19th century in the United States. It spread religion through revivals and emotional preaching and sparked a number of reform movements. Revivals were a key part of the movement and attracted hundreds of converts to new Protestant denominations. The Methodist Church used circuit riders to reach people in frontier locations.

The Methodist Episcopal Church (MEC) was the oldest and largest Methodist denomination in the United States from its founding in 1784 until 1939. It was also the first religious denomination in the US to organize itself nationally. In 1939, the MEC reunited with two breakaway Methodist denominations to form the Methodist Church. In 1968, the Methodist Church merged with the Evangelical United Brethren Church to form the United Methodist Church.
