A national controversy in the early 1900s, The Michigan Relics became the focus of intense investigation by church leaders concerned that these artifacts could be proof of the lost tribes of Israel inhabiting North America during the third and fourth centuries. Early scientists and academics dismissed the artifacts as frauds and yet more were discovered for 30 years in burial mounds throughout the state of Michigan. The artifacts passed into storage and were mostly forgotten until the last decade of the 20th century when new research brought the controversy back to life.
