    1517

    Biblical studies professor Martin Luther finds out that another religious leader has supposedly told followers that buying an indulgence, or making payments to the Roman Catholic Church, was a way to obtain forgiveness of a person’s sins. Luther writes the Ninety-five Theses. This document criticizes the selling of indulgences. Protestants consider publication of the theses to be the beginning of the Reformation.

    Luther publicly disagrees with other religious reformers on issues of theology. The reform movement splinters. Reformers called Anabaptists emerge.
