Those early reformers influenced German monk Martin Luther, who spread the Protestant Reformation. Originally, Luther intended to reform the Roman Catholic Church rather than break it up. Reformation in Germany diversified quickly as did the earlier Hussites in Bohemian Crown, and other reform impulses arose independently of Luther. The spread of Gutenberg's printing press provided the means for the rapid dissemination of religious materials in local languages. Similar to his predecessors, Martin Luther wrote "Ninety-Five Theses" on the sale of indulgences in 1517. Soon, the Reformed tradition began in Switzerland under the leadership of Huldrych Zwingli in 1519. The Reformation evolved into a large debate involving theologians throughout most of Europe. The political separation of the Church of England from Rome under Henry VIII brought England alongside this movement. The work and writings of John Calvin helped establish a loose consensus among various groups in Switzerland, Scotland, the Netherlands, Hungary, Germany and elsewhere. Calvinism within the Reformed tradition separated into specific subgroups like the Continental Reformed, Presbyterianism, Congregationalism and a variety of English dissenters, including the Puritans. Other important movements that emerged during the Reformation include Anabaptism, Arminianism, the Baptist movement and Unitarianism.
