In the not-too-distant past, it was against the law in many states for people of different races to marry. Richard and Mildred Loving got married in Washington, DC in 1958 and returned to their hometown in Virginia as criminals.
When they went to trial, the judge found them guilty and sentenced them to a jail term of one to three years. However, the judge told the Lovings that he would suspend the sentence if they agreed to leave Virginia for a period of twenty five years. Given the choice between imprisonment and banishment, they chose banishment. The Lovings moved to Washington, DC.
The Lovings filed a suit challenging the law. After a nine-year battle, on June 12, 1967, the US Supreme Court handed down a decision in the case of Loving vs. Virginia that did away with the remaining miscegenation laws. The Loving Day project promotes the celebration of this milestone on or around June 12th.
