The Mormons, a religious group, were persecuted in Illinois and their leader, Joseph Smith, was murdered
In 1846, the Mormons left for the Great Salt Lake, hoping to settle there
Their new leader, Brigham Young, gave instructions on how to survive the journey
He split his 1500 followers into groups
Everyone had a specific role within their group
They formed their wagons into a circle, for safety
He insisted on discipline and regular rest
Between 1847 and 1869, 70 000 Mormons followed the 'Mormon Trail'
