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: 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 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 5: Sheldon Axler: Sheldon Jay Axler (born 6 November 1949, Philadelphia) is an American mathematician, professor of mathematics and the Dean of the College of Science and Engineering at San Francisco State University.

Document 6: John Robert Kline: John Robert Kline (1891–1955) was a US-American Professor of Mathematics at the University of Pennsylvania from 1920 to 1955. A Ph.D. student of Robert Lee Moore, he was a Guggenheim Fellow in 1925, later Chairman of the Department of Mathematics from 1933 to 1954 and Thomas A. Scott Professor of Mathematics from 1941 to 1955. His doctoral students include Lida Barrett, Arthur Milgram, Athanasios Papoulis, Dudley Weldon Woodard, Leo Zippin, and William Waldron Schieffelin Claytor.
Document 7: 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.

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 9: Karel deLeeuw: Karel deLeeuw, or de Leeuw ( – ), was a mathematics professor at Stanford University, specializing in harmonic analysis and functional analysis.
Document 10: 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 11: John L. Kelley: John L. Kelley (December 6, 1916, Kansas – November 26, 1999, Berkeley, California) was an American mathematician at University of California, Berkeley who worked in general topology and functional analysis.
Document 12: Benjamin Franklin Kelley: Benjamin Franklin Kelley (April 10, 1807 – July 16, 1891) was an American soldier who served as a brigadier general in the Union Army during the American Civil War. He played a prominent role in several military campaigns in West Virginia and Maryland.
Document 13: Louis Kauffman: Louis Hirsch Kauffman (born February 3, 1945) is an American mathematician, topologist, and professor of Mathematics in the Department of Mathematics, Statistics, and Computer science at the University of Illinois at Chicago. He is known for the introduction and development of the bracket polynomial and the Kauffman polynomial.
Document 14: 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 15: 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.
