In the winter of 1510-1511 Martin Luther, an Augustinian monk from Erfurt, Germany, made a pilgrimage to Rome on behalf of his religious order. During the trip he and his companion monk met people and saw things that had a profound effect on both of them. Luther would go on to be the catalyst for the revolutionary movement known as the Protestant Reformation, and his trip to Rome would be part of the backdrop to the course he would eventually travel. Now find out what the trip to Rome was all about and the consequences it had for the Christian world.
