Brigham Young announces policy of denying priesthood to all those of black African ancestry, even "if there never was a prophet, or apostle of Jesus Christ spoke it before" because "negroes are the children of old Cain. . . . any man having one drop of the seed of Cain in him cannot hold the priesthood." Contrary to Joseph Smith's example in authorizing the ordination of Elijah Abel, this is LDS policy for next 126 years. Young announces this policy in connection with Utah legislature's legalization of African-American slavery. The law provides for only one interference with property rights of slave-owners: "if any master or mistress shall have sexual or carnal intercourse with his or her servant or servants of the African race, he or she shall forfeit all claim to said servant or servants to the commonwealth; and if any white person shall be guilty of sexual intercourse with any of the African race, they shall be subject, on conviction thereof, to a fine of not exceeding one thousand dollars, nor less than five hundred, to the use of the Territory, and imprisonment not exceeding three years."
