Methodism is a Protestant Christian denomination that originated in 18th-century England as a revival movement within the Church of England. It was founded by John Wesley, along with his brother Charles and others, who emphasized personal holiness, disciplined spiritual practices, and social justice. The term "Methodist" was initially used to mock their methodical approach to religion but was later embraced by the group. 

The movement grew rapidly, fueled by open-air preaching, small group meetings, and a strong commitment to spreading the gospel among the working class and marginalized communities. Methodism formally separated from the Church of England in the late 18th century and expanded globally, particularly in the United States, where it became one of the largest denominations during the Second Great Awakening. 

Key aspects of Methodism include a focus on grace, salvation by faith, and a commitment to social reform, such as advocating for education, abolition, and temperance. Today, Methodism encompasses various branches, including the United Methodist Church, and remains a significant global Christian tradition.
