Bleeding Kansas (14h 50min, jun 1, 1854 y – 1h 34min, jan 1, 1861 y)
Description:
When abolitionists and slave owners meet they fought to death. They didn't like each other because the abolitionists were against slavery and slaver owners wanted their slaves. This was created because of popular sovereignty which the population voted where if they wanted slave or free state. This was one important result that leaded to the civil war.
