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
