What Is the Most Powerful Single Letter of All Time?

On October 31st, 1517, Martin Luther sends his letter to the local Archbishop complaining about the immodest sale of indulgences in the Holy Roman Empire. The 95 Theses were later posted at the Wittenberg All Saints Church Store and quickly published in various cities in northern Germany. And though Luther initially intended his disputation as a means for scholarly argument in the Church and aligned academies, it turns out nobody really cared about nerd ass scholastic points. They wanted something spicy.
