When and How was Nebraska acquired by the US?

Nebraska was acquired by the United States through the Louisiana Purchase in 1803, when the U.S. purchased a vast territory from France. The region that is now Nebraska was initially part of the unorganized territory established by the Missouri Compromise in 1820. It became a part of the Nebraska Territory when it was created in 1854, following the passage of the Kansas-Nebraska Act. This act allowed settlers in the territory to determine whether they would allow slavery, leading to significant conflict known as "Bleeding Kansas."
