History
Monmouth was settled in about 1824. The town established in 1831 was originally going to be called Kosciusko (the name was drawn out of a hat), but the founders of the town feared that it would be difficult to spell and pronounce. The name 'Monmouth' was put forward by a resident who had lived in Monmouth County, New Jersey.
In 1841, Latter Day Saint movement founder Joseph Smith appeared before Judge Stephen A. Douglas in an extradition hearing held at Monmouth's Warren County courthouse. The hearing, which was to determine whether Smith should be returned to Missouri to face murder charges, resulted in freedom for the defendant, as it was determined that his arrest had been invalid. Attorney Orville Browning, who would assume Douglas's Senate seat following his death, represented Smith.
Gunfighter and law man Wyatt Earp was born in Monmouth. Controversial Civil War general Eleazer A. Paine practiced law there for many years. Abner C. Harding, Civil War General and Republican Congressman, lived in Monmouth and is buried in Monmouth Cemetery. Ronald Reagan lived in Monmouth for a while as a child when his father worked as a shoe salesman at the Colwell Department Store. Mass murderer Richard Speck lived in Monmouth briefly as a child, and again in the spring of 1966.
