Calls for reform in the church came from many quarters in early-sixteenth-century Europe — from educated laypeople such as Christian humanists and urban residents, from villagers and artisans, and from church officials themselves. This dissatisfaction helps explain why the ideas of Martin Luther, an obscure professor from a new and not very prestigious German university, found a ready audience. Within a decade of his first publishing his ideas (using the new technology of the printing press), much of central Europe and Scandinavia had broken with the Catholic Church in a movement that came to be known as the Protestant Reformation. In addition, even more radical concepts of the Christian message were being developed and linked to calls for social change.
