In the nineteenth century, it was a common belief that Native Americans were the descendants of the Ten Lost Tribes of Israel. Ethan Smith wrote on this topic, and in so doing, challenged the dismissal of the Indigenous Americans by European settlers.
Smith used biblical scripture, similarities in the Hebrew and Native American languages and their name for God, and other points of evidence to prove the connection between Israel and the First Nations. From there he showed how the reunited Hebrew tribes would be restored to Zion before the end of the world.
Perhaps the most fascinating aspect of Smith's book is that it is said to have influenced the Book of Mormon, which was published about seven years after later.
As a child, Smith moved away from religion after his parents died but found his way back before he turned 20 and worked in the ministry until his death. Smith wrote several books while serving in the ministry in which he explored prophecies and baptism, among other subjects. But this book remains one of the most controversial of all his publications.
