In 1854 the Kansas-Nebraska act was passed and had created two new territories (Kansas and Nebraska). A conflict arose when the U.S. Congress ruled that the question of slavery in each state should be decided by popular sovereignty. This was the start of “Bleeding Kansas”. The kansas territory became the center of attention in the battle between the north and the south. The southerners who voted for the kansas-nebraska act thought that kansas would enter the union as a slave state and the republican party thought that it would remain a free state.
Northern people started to work under the rules of senator Douglas because of popular sovereignty, in order for them to get kansas admitted as a free state. A group of abolitionists called the “border ruffians” raid into kansas causing trouble and violence for both the north and south. The most famous of these abolotionists was Jhon Brown, a noted spy who felt he was sent from god to free slaves in the south and the west.
