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.
History of Kansas
Meanwhile, by the summer of 1853, it was clear that eastern Kansas would soon be opened to American settlers. The Commissioner of the Bureau of Indian Affairs, negotiated new treaties that would assign new reservations with annual federal subsidies for the Indians. Nearly all the tribes in the eastern part of the Territory ceded the greater part of their lands prior to the passage of the Kansas territorial act in 1854, and were eventually moved south to the future state of Oklahoma.
