  • Bloody Kansas

    A series of guerilla wars erupted between the abolitionists and the pro-slavery forces in Kansas, primarily because of the Kansas-Nebraska act. This led to increased debates around the country about the issue of slavery. John Brown was included in these wars, as he led the Pottawatomie raid that resulted in death and injury.

    In the presidential election of 1856, James Buchanan was elected president over the incumbent president Millard Fillmore. This was the first time in US history where the incumbent president was beaten when running for office again.

  • Dred Scott

    In 1857, the Supreme Court ruled against Dred Scott, an African American man who wanted to be free from his owner. They said that a black man cannot be a citizen, and the Missouri Compromise was unconstitutional, reversing the idea that states could have popular sovereignty when it comes to slavery. This was a major victory for the south, which increased resentment among northerner abolitionists.

  • Lecompton Constitution

    This constitution was proposed by pro-slavery advocates, and it stated that Kansas would protect slavery in the state, as well as prohibit slaves from becoming citizens in the state. It was rejected in the state, and never went into effect. However, this was a major attempt by the south to increase their control in the western states. This led to boycotts from the abolitionist movement, increasing hostility in Kansas.

    John Brown attacked an armory in Harpers Ferry, in order to start a slave rebellion. They took the armory successfully, but when word spread, they were forced to surrender the next day by the US military.

    After his failed raid on Harpers Ferry, John Brown was tried for treason and was found guilty. He was sentenced to execution. Before he was executed, he handed a note to a guard, which stated that the fight over slavery could only result in bloodshed. This was a prediction of the Civil War, and his death resulted in the north treating him like a martyr, increasing hatred for the south, and the pro-slavery cause.
  • Election of 1860

    After Douglas offered his infamous freeport doctrine, the Democratic Party completely split, with one side supporting the nominee, and the other resenting his anti-slavery sentiments. This allowed Abraham Lincoln to ultimately win the election. This showcased the political divide in the US had reached an irreversible point, and was the final straw before the south finally seceded from the Union.
  • Secession

    On December 20, 1860, seven states broke off from the Union, in order to protect slavery from being eradicated across the US. They formed the Confederacy, which eventually consisted of eleven states, including half of Virginia. This is significant because it was the event that would start the Revolutionary War, as President Lincoln would send troops into Confederate territory to end the rebellion.
