The word "Protestantism" had its origin when German princes and free cities at the Diet of Speyer (1529), petitioned or "protested" against the imperial ban adopted by the Diet against Martin Luther and its stance against the Reformation. Lutherans in Germany began using it. Swiss and French more often used "Reformed". The Anglicans use "Catholic", "Reformed" and "Protestant", however the Anglican Church is not always regarded as part of Protestantism because it kept most of the doctrine of the Roman Catholic Church from which it separated.
