full_context: Document 1: Kansas–Nebraska Act: The Kansas -- Nebraska Act divided the nation and pointed it toward civil war. The Act itself virtually nullified the Missouri Compromise of 1820. The turmoil over the act split both the Democratic and Whig parties and gave rise to the Republican Party, which split the United States into two major political camps, the Republican North and the Democratic South.
Document 2: American Civil War: The American Civil War (also known by other names) was a war fought in the United States from 1861 to 1865. As a result of the long - standing controversy over slavery, war broke out in April 1861, when Confederate forces attacked Fort Sumter in South Carolina, shortly after U.S. President Abraham Lincoln was inaugurated. The nationalists of the Union proclaimed loyalty to the U.S. Constitution. They faced secessionists of the Confederate States, who advocated for states' rights to expand slavery.
Document 3: Camp Defiance: The new camp, named Camp Defiance, was established December 17. Camp Defiance was located on the south side of Mine Creek and just barely inside the Kansas border.
Document 4: Battle of the Little Bighorn: The Battle of the Little Bighorn, known to the Lakota and other Plains Indians as the Battle of the Greasy Grass and commonly referred to among white Americans as Custer's Last Stand, was an armed engagement between combined forces of the Lakota, Northern Cheyenne, and Arapaho tribes and the 7th Cavalry Regiment of the United States Army. The battle, which resulted in the defeat of US forces, was the most significant action of the Great Sioux War of 1876.

Document 5: Southern California: Subsequently, Californios (dissatisfied with inequitable taxes and land laws) and pro-slavery southerners in the lightly populated "Cow Counties" of southern California attempted three times in the 1850s to achieve a separate statehood or territorial status separate from Northern California. The last attempt, the Pico Act of 1859, was passed by the California State Legislature and signed by the State governor John B. Weller. It was approved overwhelmingly by nearly 75% of voters in the proposed Territory of Colorado. This territory was to include all the counties up to the then much larger Tulare County (that included what is now Kings, most of Kern, and part of Inyo counties) and San Luis Obispo County. The proposal was sent to Washington, D.C. with a strong advocate in Senator Milton Latham. However, the secession crisis following the election of Abraham Lincoln in 1860 led to the proposal never coming to a vote.
Document 6: Battle of Mine Creek: The Battle of Mine Creek, also known as the Battle of the Osage, was a battle that occurred on October 25, 1864, in Kansas as part of Price's Raid during the American Civil War.

Document 7: Kansas Legislature: During Kansas' first elections for a territorial government on March 30, 1855, nearly 5,000 Missouri men, led by United States Senator David Rice Atchison and other prominent pro-slavery Missourians, entered the territory, took over the polling places, and elected pro-slavery candidates. The elections resulted in 13 pro-slavery members of the upper house of the territorial legislature and one free - state member, who resigned. The lower house ended up with 25 pro-slavery members and one free - state member. Free - Staters immediately cried foul, naming the new Kansas Territorial Legislature the Bogus Legislature. After meeting for one week in Pawnee at the direction of Territorial Governor Andrew Reeder, the thirty - eight pro-slavery legislators reconvened at the Shawnee Manual Labor School between July 16 and August 30, 1855, and began crafting over a thousand pages of laws aimed at making Kansas a slave state.
Document 8: American Civil War: The American Civil War (commonly known as the Civil War in the United States) was fought in the United States from 1861 to 1865. The result of a long - standing controversy over slavery, war broke out in April 1861, when Confederates attacked Fort Sumter in South Carolina, shortly after President Abraham Lincoln was inaugurated. The nationalists of the Union proclaimed loyalty to the U.S. Constitution. They faced secessionists of the Confederate States of America, who advocated for states' rights to travel with slave attendants in the Americas or abolished tariffs on cotton and imports.
Document 9: Battle of the Little Bighorn: The Battle of the Little Bighorn, known to the Lakota and other Plains Indians as the Battle of the Greasy Grass and also commonly referred to as Custer's Last Stand, was an armed engagement between combined forces of the Lakota, Northern Cheyenne, and Arapaho tribes and the 7th Cavalry Regiment of the United States Army.

Document 11: Second Battle of Newtonia: The Second Battle of Newtonia was fought on October 28, 1864, in Newton County, Missouri, as part of Major General Sterling Price's Missouri Expedition of the American Civil War.
Document 12: Military history of the United States: Sectional tensions had long existed between the states located north of the Mason–Dixon line and those south of it, primarily centered on the "peculiar institution" of slavery and the ability of states to overrule the decisions of the national government. During the 1840s and 1850s, conflicts between the two sides became progressively more violent. After the election of Abraham Lincoln in 1860 (who southerners thought would work to end slavery) states in the South seceded from the United States, beginning with South Carolina in late 1860. On April 12, 1861, forces of the South (known as the Confederate States of America or simply the Confederacy) opened fire on Fort Sumter, whose garrison was loyal to the Union.
Document 13: Bleeding Kansas: Bleeding Kansas, Bloody Kansas or the Border War was a series of violent political confrontations in the United States between 1854 and 1861 involving anti-slavery ``Free - Staters ''and pro-slavery`` Border Ruffian'', or ``southern ''elements in Kansas. At the heart of the conflict was the question of whether Kansas would allow or outlaw slavery, and thus enter the Union as a slave state or a free state. The Kansas -- Nebraska Act of 1854 called for`` popular sovereignty'' -- that is, the decision about slavery was to be made by the settlers (rather than outsiders). It would be decided by votes -- or more exactly which side had more votes counted by officials. Pro-slavery forces said every settler had the right to bring his own property, including slaves, into the territory. Anti-slavery ``free soil ''forces said the rich slaveholders would buy up all the good farmland and work it with black slaves, leaving little or no opportunity for non-slaveholders. As such, Bleeding Kansas was a conflict between anti-slavery forces in the North and pro-slavery forces from the South over the issue of slavery in the United States, and its violence indicated that compromise was unlikely, and thus it presaged the Civil War.
Document 14: Bleeding Kansas: Through the Missouri Compromise of 1820, Congress kept a tenuous balance of political power between North and South. In May 1854, the Kansas -- Nebraska Act, created from unorganized Indian lands and territories of Kansas and Nebraska, permitted residency by U.S. citizens, who were to determine their state's slavery status and seek admission to the Union. Immigrants supporting both sides of the question arrived in Kansas to establish residency and gain the right to vote. However, Kansas Territory officials were appointed (1854) by the pro-slavery administration of President Franklin Pierce (in office 1853 -- 1857), and thousands of non-resident pro-slavery Missourians entered Kansas with the goal of winning elections. They captured territorial elections, sometimes by fraud and intimidation. In response, Northern abolitionist elements flooded Kansas with ``free - soilers. ''Anti-slavery Kansas residents wrote the first Kansas Constitution (1855) and elected the Free State legislature in Topeka; this stood in opposition to the pro-slavery government in Lecompton. The two Territorial governments increased as well as symbolized the strife of Bleeding Kansas.
Document 15: Battle of Peachtree Creek: The Battle of Peachtree Creek was fought in Georgia on July 20, 1864, as part of the Atlanta Campaign in the American Civil War.

Sherman's Union army which was perched on the doorstep of Atlanta. The main armies in the conflict were the Union Army of the Cumberland, commanded by Maj. Gen.
