In the 19th century, Captain William Morgan, a member of the Royal Arch Degree within Freemasonry, took a bold stance. He pledged to unveil the hidden oaths and rituals of the Masonic Lodge, even though this challenged his own binding blood oath as a Freemason. This audacious mission led to a dramatic turn of events – certain Freemasons kidnapped & murdered him in an attempt to suppress his revelations.  After Captain William Morgan's death, his manuscripts were reportedly handed over to David C. Miller, a former Mason who had turned against the organization. Miller, along with another Anti-Masonic activist named Henry L. Valance, worked to compile and publish Morgan's writings as a book titled "Illustrations of Masonry." This book, containing Morgan's exposé of Freemasonry, was published in 1826, a year after Morgan's disappearance and presumed death. It played a significant role in further fueling the Anti-Masonic sentiment and the growth of the Anti-Masonic movement in the United States, starting the first third party in America, known as the Anti-Masonic Party in 1828.
