When was interracial marriage allowed in New Hampshire?

Interracial marriage was effectively legalized in New Hampshire in 1878 when the state's Supreme Court ruled that a law prohibiting marriage between individuals of different races was unconstitutional. This decision came during a period of increasing recognition of civil rights, although societal acceptance varied widely. By the mid-20th century, interracial marriage was more broadly accepted, especially following the landmark Supreme Court decision in Loving v. Virginia in 1967, which invalidated laws prohibiting interracial marriage across the United States.
