What states voted against the 13 amendment?

The states that voted against the 13th Amendment, which abolished slavery in the United States, were Delaware, Kentucky, and Mississippi. While the amendment passed in Congress and was ratified by the necessary states, these three states either rejected it or did not ratify it initially. However, Mississippi eventually ratified the amendment in 1995, and Kentucky formally ratified it in 1976, while Delaware remained the only state that never ratified it.
