Leavenworth County, Kansas, has a rich and varied history that stretches back to its early settlement in the mid-1800s. The area was initially inhabited by Native American tribes, most notably the Kickapoo and Delaware tribes. In 1827, Fort Leavenworth was established by the United States Army, serving as an important outpost for the growing Western frontier.

The arrival of white settlers in the 1850s brought significant changes to the region. In 1854, Leavenworth City was founded, and it quickly became a bustling center of trade and commerce. The city was an important stop along the Oregon and Santa Fe Trails, playing a crucial role in westward expansion. Leavenworth thrived as a transportation hub, with steamboats navigating the Missouri River and the development of railroads in the area.

During the Civil War, Leavenworth County was deeply divided, reflecting the broader conflicts of the nation. The county's strategic location made it a contested area, and the town of Leavenworth became an important military supply base for Union forces. The region was also a hotbed of political activity, with pro-slavery and abolitionist factions clashing over their conflicting ideologies.

In the decades following the war, Leavenworth County continued to evolve and grow. Agriculture became a leading industry, with wheat and corn being major crops. The county also played a role in the development of industry, particularly in the manufacturing of cement and bricks.
