The Fundamentals A Testimony To The Truth, commonly known as The Fundamentals, is a compelling collection of ninety essays published between 1910 and 1915 by the Testimony Publishing Company of Chicago. Designed to present a fresh statement on the core principles of Christianity, this influential work arose from concerns over certain theological shifts associated with liberal Christianity, particularly biblical higher criticism. It is widely recognized as the cornerstone of modern Christian fundamentalism. Authored by sixty-four prominent writers from various major Protestant denominations, these essays were distributed free of charge to ministers, missionaries, theology professors, YMCA and YWCA leaders, Sunday school superintendents, and other Protestant religious figures across the United States and other English-speaking nations. An impressive three million volumes (250,000 sets) were circulated. (Summary from Wikipedia)
