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.
Kansas Territory
As early as June 10, 1854, the Missourians held a meeting at Salt Creek Valley, a trading post west from Fort Leavenworth, at which a "Squatter's Claim Association" was organized. They said they were in favor of making Kansas a slave state if it should require half the citizens of Missouri, musket in hand, to emigrate there. According to these emigrants, abolitionists would do well not to stop in Kansas Territory, but keep on up the Missouri River until they reach Nebraska Territory, which was anticipated to be a free state. Before the first arrival of Free-State emigrants from the northern and eastern States, nearly every desirable location along the Missouri River had been claimed by men from western Missouri, by virtue of the preemption laws.
