Methodism, or the Methodist movement, is a group of Protestant denominations. The movement started in Britain in the 18th century and spread to the United States and the British Empire. Originally it was popular with workers, poor farmers, and slaves. Mr. John Wesley started Methodism. He was a priest of the Church of England. His brother Charles Wesley was a famous writer of Church music. There are many denominations that trace their roots to the Wesley brothers. Many have the word Methodist as part of their name, but other do not.
