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 Legislature
Following long debates in both the U.S. House of Representatives and the Senate, on January 29, 1861, President James Buchanan authorized Kansas to become the 34th state of United States. It had entered into the Union as a free state. Only six days later, the Confederate States of America formed between seven Southern states that had seceded from the United States in the previous two months.
