Why were people segregated in the north?

Segregation was not mandated by law in the Northern states, but a de facto system grew for schools, in which nearly all black students attended schools that were nearly all-black. In the South, white schools had only white pupils and teachers, while black schools had only black teachers and black students.

But state-sponsored segregation also existed in the North, and thousands of people joined in civil rights movements outside the South, from New York City to Boston to Detroit.

history

here are some events that to cause increased conflict between the north and south

1) mexican cession- gaining modern day california, utah, arizona, and new mexico from mexico. caused southern and northern politicians to fight over whether or not there would be slavery in these newly acquired territories.

3) kansas- nebraska act- disagreements over whether or not kansas and nebraska would be free or slave states caused issues between northern and southern politicians in congress.

4) bleeding kansas- this fighting took place in kansas after congress allowed this territory to vote on whether or not they would have slavery. citizens were killed and buildings were destroyed during this fighting.
