By 1860 how many states legally
allowed slaves?

i went remember the answer, but i wanted to double check.

"At the start of the Civil War, there were 34 states in the United States, 15 of which were slave states. Of these, 11 slave states declared their secession from the United States to form the Confederacy."

so that means 15 states were slave states

i looked it up btw, and put quotations. pls dont report me

Explanation:

abraham lincoln, according to anyone who was connected with agriculture, represented the worst of northern politicians. shortly after lincoln was elected, south carolina seceded from the union. they along with other southern states, retained their anger. in a way, it was their own fault: the democrats were split in the south. some wanted slavery to be extended in other states that were about to join the union and some didn't want it badly enough. lincoln had a solid backing from his party: the republicans were united in not wanting slavery to be expanded.
