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 (the Methodist Protestant Church and the Methodist Episcopal Church, South) to form the Methodist Church. In 1968, the Methodist Church merged with the Evangelical United Brethren Church to form the United Methodist Church.
The MEC's origins lie in the First Great Awakening when Methodism emerged as an evangelical revival movement within the Church of England that stressed the necessity of being born again and the possibility of attaining Christian perfection. By the 1760s, Methodism had spread to the Thirteen Colonies, and Methodist societies were formed under the oversight of John Wesley. As in England, American Methodists remained affiliated with the Church of England, but this state of affairs became untenable after the American Revolution. In response, Wesley ordained the first Methodist elders for America in 1784. Under the leadership of its first bishops, Thomas Coke and Francis Asbury, the Methodist Episcopal Church adopted episcopal polity and an itinerant model of ministry that saw circuit riders provide for the religious needs of a widespread and mobile population.
