Protestantism is a form of Christian faith and practice. It began in northern Europe in the early 16th century. At that time, they were against some parts of Roman Catholicism. Together with Eastern Orthodoxy and Roman Catholicism, Protestantism became one of the three greatest forces in Christianity. Protestantism much influenced the culture, beliefs, and economy of the place it became important in.
The word Protestantism was first used by German princes and free cities at the Diet of Speyer (1529), when they were speaking against the Reformation. Lutherans in Germany began using it. Swiss and French more often used Reformed. The Anglicans use Catholic, Reformed and Protestantism, however the Anglican Church is not always regarded as part of Protestantism because it has kept most of the doctrine of the Roman Catholic Church from which it separated from.
Martin Luther, a doctor of theology and a monk, said that the church should return to its roots, and give more weight to what is written in the Bible. Luther thought that the Church had gone too far away from the original teachings.
