In early-sixteenth-century Europe a wide range of people had grievances with the church. Educated laypeople such as Christian humanists and urban residents, villagers and artisans, and church officials themselves called for reform. This widespread 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, and even more radical concepts of the Christian message were being developed and linked to calls for social change.
