Kansas Territory
The Territory of Kansas was an organized incorporated territory of the United States that existed from May 30, 1854, until January 29, 1861, when the eastern portion of the territory was admitted to the Union as the state of Kansas.
Kansas–Nebraska Act
Prior to the organization of the Kansas–Nebraska territory in 1854, the Kansas and Nebraska Territories were consolidated as part of the Indian Territory. Throughout the 1830s, large-scale relocations of Native American tribes to the Indian Territory took place, with many Southeastern nations removed to present-day Oklahoma, a process ordered by the Indian Removal Act of 1830 and known as the Trail of Tears, and many Midwestern nations removed by way of treaty to present-day Kansas. Among the latter were the Shawnee, Delaware, Kickapoo, Kaskaskia and Peoria, Ioway, and Miami. The passing of the Kansas–Nebraska Act came into direct conflict with the relocations. White American settlers from both the free-soil North and pro-slavery South flooded the Northern Indian Territory, hoping to influence the vote on slavery that would come following the admittance of Kansas and, to a lesser extent, Nebraska to the United States.
