On October 31, 1517, a lone monk pushed his way through the crowds milling around the streets of Wittenberg, a small university town in eastern Germany, and made his way towards the church. Arriving at the church door, he nailed to that door a list of 95 serious objections – this being his formal gesture of inviting the townspeople to a public discussion of these abuses of the church.
At the time, only a few took much notice of his actions, but within a few weeks, people all over Europe were discussing this. A chain of events was set in motion which had profound effects for Europe, and beyond to the world, for centuries to come. That monk was Martin Luther.
