What the Ninety-Five Theses Hit Was a Debt-Service Cash FlowThe Ninety-Five Theses · 31 October 1517, Wittenberg
31 October 1517Wittenberg · MainzPettegree 2015By 1514 the twenty-four-year-old Albrecht of Brandenburg already held two sees and was angling for Mainz, an archbishopric that carried an elector's vote. Canon law barred pluralism; Rome priced a dispensation at over twenty thousand ducats. Albrecht borrowed from the Fugger bank to pay it, and Rome licensed him to sell indulgences in his territories to service the debt: half the proceeds to Rome for the new St Peter's, half straight back to the Fuggers. The Dominican Johann Tetzel was the sales end of that cash flow.
On 31 October 1517 Luther posted his Disputation on the Power of Indulgences to Albrecht himself — not knowing that his addressee was the debtor. The theses were Latin, a set of academic debating points; within weeks they had been translated into German and reprinted in several cities. The real amplifier was the format Luther then perfected: the eight-page quarto pamphlet — cheap, readable in one sitting, and short enough to be read aloud to the illiterate. His To the Christian Nobility of the German Nation (August 1520) sold out a first run of four thousand in days. Andrew Pettegree's Brand Luther (2015) notes that even the industrial geography shifted: German printing's center of gravity moved from Cologne and Leipzig to the small town of Wittenberg.
Jan Hus was burned at Constance in 1415 on closely related arguments; with no press, the movement was contained inside Bohemia. Without printing in 1517, Luther is most likely a second Hus. The dispute is over attribution: Pettegree treats print as the decisive variable; Diarmaid MacCulloch's Reformation (2003) insists the demand — dread of purgatory, resentment of clerical privilege — was already there, and print merely let supply catch up; Robert Scribner (1981) points out that literacy was under ten percent, so the actual carriers were woodcuts and reading aloud. At issue: did the new technology light the fire, or only deliver wood already stacked?
When distribution costs collapse, the same channel amplifies the crudest version fastest — the "Luther" quoted at length in the Peasants' War of 1524 was not the Luther who did the writing.
