Was Alabama the last state to remove the law of banning interracial marriage?

No, Alabama was not the last state to remove the ban on interracial marriage. Although Alabama officially repealed its law against interracial marriage in 2000, it was actually the last state to remove such a ban from its constitution. The U.S. Supreme Court's decision in Loving v. Virginia in 1967 declared laws banning interracial marriage unconstitutional, effectively invalidating such laws across the country.
