Miami County, Kansas
When Kansas Territory was incorporated in 1854 due to the Kansas-Nebraska Act, the Missouri Compromise of 1820 was essentially repealed. Bordering the slave state of Missouri to its east, the county (Miami) and surrounding areas became a location for violence between abolitionists and the "Border Ruffians" of Missouri. These acts of violence and battles that took place primarily from 1854–1858, became known as border wars, and Kansas became known as Bleeding Kansas. Kansas Territory was not yet a state, and it was a battle on which forces would become dominant, slave or free. Many abolitionists came from other states to live in the area and ensure Kansas' entry as a state as a free, or anti-slavery one. The county's most notable abolitionist was John Brown, who moved to Osawatomie, making it the headquarters for him and his anti-slavery forces. As a result of this, Osawatomie, as well as the surrounding countryside and communities became the center for several battles and acts of violence during this period. Near Osawatomie are historic sites of John Brown, such as his famous Civil War lookout.
Oklahoma Panhandle
The Compromise of 1850 also established the eastern boundary of New Mexico Territory at the 103rd meridian, thus setting the western boundary of the strip. The Kansas-Nebraska Act of 1854 set the southern border of Kansas Territory as the 37th parallel. This became the northern boundary of "No Man's Land". When Kansas joined the Union in 1861, the western part of Kansas Territory was assigned to Colorado Territory, but did not change the boundary.
