All of the conflicts in the Mormon War occurred in a corridor 100 miles (160 km) to the east and northeast of Kansas City, Missouri.
As a result of the war, nearly all Mormons in Missouri, estimated at more than 10,000, were forced to leave the state.
Tensions rose in Clay County as the Mormon population grew.
When Joseph Smith and volunteers rode to Adam-ondi-Ahman to assess the situation, they discovered there were no truths to the rumors.
When the Mormons heard a rumor that Judge Adam Black was gathering a mob near Millport, one hundred armed men, including Joseph Smith, surrounded Black's home.
Most of these refugees settled in or near what would become the city of Nauvoo, Illinois.
Shortly after what Mormons consider to be the restoration of the gospel, The Church of Jesus Christ of Latter-day Saints in 1830, Joseph Smith revealed that the Second Coming of Christ was near, that the City of Zion would be near the town of Independence in Jackson County, Missouri, and that his followers were destined to inherit the land held by the current settlers.
According to an article in the Elders' Journal – a Latter Day Saint newspaper published in Far West – "The Saints here are at perfect peace with all the surrounding inhabitants, and persecution is not so much as once named among them..." In 1837, problems at the Church's headquarters in Kirtland, Ohio, centering on the Kirtland Safety Society bank, led to schism.
The Church relocated from Kirtland to Far West, which became its new headquarters.The Mormon War is a name that is sometimes given to the 1838 conflict which occurred between Latter-day Saints (Mormons) and their neighbors in the northwestern region of the US state of Missouri.This conflict is also sometimes referred to as the Missouri Mormon War to differentiate it from the Utah Mormon War (also known as the "Utah War") and the lesser known Illinois Mormon War.The skirmish is often cited as the first serious violence of the 1838 Mormon War in Missouri.Rumors among both parties spread that there were casualties in the conflict.At the same time Mormons, including Sampson Avard, began to organize a secret society known as the Danites, whose purposes included obeying the church presidency "right or wrong" and expelling the dissenters from Caldwell County.
