In short: In 1517, Martin Luther's decision to nail a document to a church door changed history. This video explores how his aggressive, unfiltered rhetoric helped establish him as the father of the Protestant Reformation.

On the final day of October in 1517, the scholar and priest Martin Luther nailed a paper to the Castle Church door in Wittenberg, Germany. While many clergy members posted documents for discussion, Luther's actions ignited a massive social and religious revolution. To solidify his leadership during this era, some suggest Luther adopted a remarkably coarse way of speaking, using the blunt and profane language common to 16th-century Germany.
