How many states has laws prohibiting interracial marriage in the 19th century?

In the 19th century, several states in the United States had laws prohibiting interracial marriage. By the late 1800s, around 30 states enacted such laws, primarily targeting marriages between white individuals and people of African or Native American descent. These laws reflected the racial segregation and discriminatory attitudes prevalent during that time. It wasn't until the mid-20th century that these prohibitions were declared unconstitutional.
