Luther is said to have posted the 95 Theses on the door of the Castle Church in Wittenberg, Germany, on October 31, 1517. Church doors functioned very much as bulletin boards function on a twenty-first century college campus. The 95 Theses were quickly translated into German, widely copied and printed. Within two weeks they had spread throughout Germany, and within two months throughout Europe. This was one of the first events in history that was profoundly affected by the printing press, which made the distribution of documents and ideas easier and more wide-spread.
