Missouri was admitted to the Union as the 24th state on August 10, 1821, becoming the first state entirely west of the Mississippi River.
Daviess County, Missouri has a rich and varied history dating back to its early settlement in the 1830s. The area was initially inhabited by Native American tribes, including the Ioway and Sac and Fox nations, who used the abundant natural resources for hunting and gathering purposes. In 1836, the county was officially established and named after Joseph Hamilton Daviess, an attorney and soldier who served in the War of 1812.

The county played a significant role in the westward expansion of the United States. The pioneers who arrived in Daviess County endured harsh conditions and worked hard to establish farms and communities. The construction of the Hannibal and St. Joseph Railroad in the 1850s further facilitated growth and development in the region, providing a crucial transportation link between the East Coast and the western territories.

Daviess County was not without its challenges, as it became a major battleground during the Civil War. Confederate guerrillas, led by infamous figures such as Jesse James and William Quantrill, frequently raided the area. The Battle of Gallatin, fought in 1863, was a significant conflict that resulted in the Union Army taking control of the county.

In the years following the war, Daviess County experienced gradual economic development. Agriculture, particularly livestock and grain farming, became the backbone of the county's economy. The growth of small towns, such as Gallatin and Pattonsburg, brought services and infrastructure to the region. Today, Daviess County continues to thrive as a rural community with a strong agricultural tradition, while also providing a glimpse into its past through historic sites and landmarks.
