Luther's writings circulated widely, reaching France, England, and Italy as early as 1519. Students thronged to Wittenberg to hear Luther speak. He published a short commentary on Galatians and his Work on the Psalms. This early part of Luther's career was one of his most creative and productive. Three of his best-known works were published in 1520: To the Christian Nobility of the German Nation, On the Babylonian Captivity of the Church, and On the Freedom of a Christian.
