In 1517, Martin Luther challenged his church with a list of 95 statements. He criticized the practice of purchasing indulgences to free oneself from the burning fires of Purgatory. While intended for internal debate, his words led to a split in Catholicism between traditionalists and critics.

Luther's act launched a religious movement known as the Protestant Reformation, which influenced religion for centuries to come.

This online exhibit walks you from the origins of the Reformation to its impact on hundreds of denominations that characterize American religion today. You'll find unique digital content from the University of Arizona Special Collections, including pamphlets, texts, illustrations, and more.
