Martin Luther was a German theologian and religious reformer who was the catalyst of the 16th-century Protestant Reformation.
He knew that the Catholic Church was spreading blasphemy to believers in ways that seemed too obvious to be faulted, so he decided to help guide believers with an inspiration to challenge the temporal and spiritual dominance of the Church of Rome. It fell to others to shape the contours of the earthshaking revolution he had unleashed, but they still found themselves working in the towering shadow cast over them by the renegade monk of Wittenberg.
