On 31 October 1517, Luther posted his "Ninety-five Theses" on the door of the All Saints' Church, which served as a notice board for university-related announcements. These were points for debate that criticized the Church and the Pope. The most controversial points centered on the practice of selling indulgences (especially by Johann Tetzel) and the Church's policy on purgatory. The reform movement soon split along certain doctrinal lines. Religious disagreements between various leading figures led to the emergence of rival Protestant churches. The most important denominations to emerge directly from the Reformation were the Lutherans, and the Reformed/Calvinists/Presbyterians. The process of reform had decidedly different causes and effects in other countries. In England, where it gave rise to Anglicanism, the period became known as the English Reformation. Subsequent Protestant denominations generally trace their roots back to the initial reforming movements.
