Kansas has a rich history that began with Native American tribes, such as the Kaw and Osage, who inhabited the region long before European settlers arrived. In the mid-1800s, the area became a focal point in the debate over slavery, leading to violent conflicts known as Bleeding Kansas. This turmoil played a significant role in the events leading up to the American Civil War. In 1861, Kansas became the 34th state of the United States. The state's economy initially relied on agriculture, with crops like wheat and corn. Over time, Kansas developed into a center for aviation and manufacturing, contributing to its diverse economic landscape today.
