Question: Who was the conflict between in the strife of bleeding the state encompassing Paola's post?

full_context: Document 1: 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 2: 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 3: 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 4: 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 5: Paola's post: Paola's post, sometimes called Post Paola, in Miami County, Kansas, was located on the west side of Bull Creek, just west of Paola, Kansas. It was probably established in December 1861, as that was the first time it was mentioned. This post became one of the more important posts along the Kansas-Missouri border during the Civil War. It became a district headquarters in 1863. Later, in September 1864, it was designated a subdistrict headquarters, when the district headquarters was moved to Lawrence, Kansas. The military road from Fort Leavenworth to Fort Gibson ran through Paola, thus ensuring the post always had some importance.
Document 6: 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 7: Houston: By 1860, Houston had emerged as a commercial and railroad hub for the export of cotton. Railroad spurs from the Texas inland converged in Houston, where they met rail lines to the ports of Galveston and Beaumont. During the American Civil War, Houston served as a headquarters for General John Bankhead Magruder, who used the city as an organization point for the Battle of Galveston. After the Civil War, Houston businessmen initiated efforts to widen the city's extensive system of bayous so the city could accept more commerce between downtown and the nearby port of Galveston. By 1890, Houston was the railroad center of Texas.
Document 8: 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 9: Coxs Creek, Kentucky: Kentucky's second Baptist association was formed at Coxs Creek on October 29, 1785. The first post office in the community was established on November 28, 1856, with a descendant of Isaac Cox, John C. Cox, the first postmaster. By the time of the automobiles, the post office and adjacent store blocked the view of upcoming traffic on US-31, forcing the Kentucky Highway Department to order the post office moved from Coxs Creek's crossroads of US-31E/US-150 and Kentucky State Route 509 in the 1960s; the new post office is 1/2 mile south of the crossroads.
Document 10: 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. In the second largest cavalry engagement of the war, two divisions of Major General Sterling Price's Army of Missouri were routed by two Federal brigades under the command of Colonels Frederick Benteen and John Finis Philips.
Document 11: First Transcontinental Railroad: Several years after the end of the Civil War, the competing railroads coming from Missouri finally realized their initial strategic advantage and a building boom ensued. In July 1869, the H&SJ finished the Hannibal Bridge in Kansas City which was the first bridge to cross the Missouri River. This in turn connected to Kansas Pacific trains going from Kansas City to Denver, which in turn had built the Denver Pacific Railway connecting to the Union Pacific. In August 1870, the Kansas Pacific drove the last spike connecting to the Denver Pacific line at Strasburg, Colorado and the first true Atlantic to Pacific United States railroad was completed.
Document 12: Cayce, Kentucky: Cayce includes the area east and west from Willingham Bottom and Bayou de Chien Creek to Mud Creek and north and south from Moscow to the Middle Road (Kentucky Route 166). Part of the town, known as the "junction", is at the junction of Kentucky Routes 94 and 239. This is the location of the service stations and cafe. Also at that junction (on the northwest corner) is an old elementary school (now closed), with a monument out front identifying Cayce as the hometown of American cultural icon, railroad engineer Casey Jones (1863–1900), who grew up in the area.
Document 13: 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 14: 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 15: 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.
