Lawrence, Kansas
Prior to Kansas Territory being established in May 1854, most of Douglas County was part of the Shawnee Indian Reservation (created in 1830). During this period, the Oregon Trail ran parallel to the Kansas River, roughly through the area where Lawrence would eventually be situated and a hill known then as "Hogback Ridge" (i.e., Mount Oread, which sits on the water divide separating the Kansas and Wakarusa River). This area was used as a landmark and an outlook by those on the trail. While this territory was technically unopened to settlement prior to 1854, there did exist a few "squatter settlements" in the area, especially just north of the Kansas River.
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.
