EmmaWelcome to Slow English FM. This is Today in History, a programme about past events and why they matter. We share history in clear, simple English to help you understand the world and improve your English. On October 31, 1517, Martin Luther sent a letter with a set of arguments about Church practices.

EmmaLuther wrote to Albrecht of Brandenburg and enclosed his Ninety-five Theses. The theses criticized Church practices, especially the sale of indulgences. This capsule does not claim that Luther put the theses on a church door that day. Thank you for listening to Today in History on Slow English FM.
