It was at this time that what is known as the Mormon War took place.

Mormonism was a new religion founded by Joseph Smith. Joseph Smith was a shiftless, idle, jovial fellow, one of a large family as shiftless and idle as himself. He was very ignorant, but he had a wonderful imagination, and he could never tell the simplest happening of his everyday life without making a great story out of it.

When he grew to be a man he began to dream dreams and see visions, and at length he declared that a messenger from heaven had shown him where to find a golden book. No one else saw this golden book, because Smith had been warned by the angel that great punishment would fall upon him if he showed it to any one. He was, however, allowed to make a "translation" of what was written in the book. This he did, publishing it as "The Book of the Mormons" or "The Golden Bible." But it seems very likely that part of this so-called translation was really copied from a story written by a man named Spaulding which had never been published. A great deal of it was, however, copied from the Bible.

Smith, who was at this time living in the State of New York, now declared that the religion which had been revealed to him was the only true religion. He founded a Church of which he was head or "prophet" and under him were twelve apostles and other dignitaries. A few people soon joined him and gradually their numbers increased until at last they numbered several thousand.

They now became a community by themselves, they moved about from place to place, and at length settled in Illinois where they built a city called Nauvoo.

Smith had many revelations. If he wanted a horse or cart he had a revelation saying that it was to be given to him. If he wanted his followers to do anything, again he had a revelation saying it was to be done. So he ruled like an autocrat and did whatever he chose. And while at Nauvoo he had a revelation which said it was quite lawful for men to marry as many wives as they wanted.

Soon the people of Illinois began to dislike the Latter-day Saints, as they called themselves. For they stole horses and cattle and all sorts of things belonging to other settlers. And once anything was stolen by the Mormons, it was impossible to get it back. For if a stranger went to their city, and showed by his questions that he had come to look for something he had lost, he soon found himself followed by a Mormon who silently whittled a stick with a long sharp knife. Soon the man would be joined by another, also whittling a stick with a long knife. Then another and another would silently join the procession, until the stranger could stand it no longer and hastily departed homeward.

So as time went on the people grew more and more angry with the
Mormons. And at length their anger burst into fury, and, in 1844,
Smith and one of his brothers were lynched by the mob.

The Mormons were greatly cast down at the death of their Prophet, but they soon found a new leader in Brigham Young, one of the twelve apostles.

But this change of leader brought no peace between the Mormons and their neighbours. Complaints of theft grew more and more frequent. Both sides went about armed, murders were committed, and the settlers burned many of the Mormon farms.
