Evangelicalism ( /ˌiːvænˈdʒɛlɪkəlɪzəm, ˌɛvæn-, -ən-/), also called evangelical Christianity or evangelical Protestantism, is a worldwide interdenominational movement within Protestant Christianity that emphasizes the centrality of sharing the "good news" of Christianity, being " born again" in which an individual experiences personal conversion, as authoritatively guided by the Bible, God's revelation to humanity. The word evangelical comes from the Greek word for ' good news' (euangelion).

The theological nature of evangelicalism was first explored during the Protestant Reformation in 16th century Europe. Martin Luther's Ninety-Five Theses in 1517 emphasized that scripture and the preaching of the gospel had ultimate authority over the practices of the Church. The origins of modern evangelicalism are usually traced to 1738, with various theological streams contributing to its foundation, including Pietism and Radical Pietism, Puritanism, Quakerism and Moravianism (in particular its bishop Nicolaus Zinzendorf and his community at Herrnhut). Preeminently, John Wesley and other early Methodists were at the root of sparking this new movement during the First Great Awakening. Today, evangelicals are found across many Protestant branches, as well as in various denominations around the world, not subsumed to a specific branch. Among leaders and major figures of the evangelical Protestant movement were Nicolaus Zinzendorf, George Fox, John Wesley, George Whitefield, Jonathan Edwards, Billy Graham, Bill Bright, Harold Ockenga, Gudina Tumsa, John Stott, Francisco Olazábal, William J. Seymour, and Martyn Lloyd-Jones.

The movement has long had a presence in the Anglosphere before spreading further afield in the 19th, 20th, and early 21st centuries. The movement gained significant momentum during the 18th and 19th centuries with the Great Awakening in Great Britain and the United States. ( Full article...)
