Senator Hiram Revels may appear on a stamp some day. Here a brief summary of his life and a link to the full article.
Revels was elected by a vote of 81 to 15 in the Mississippi State Senate to finish the term of one of the state’s two seats in the US Senate left vacant since the Civil War. The seat had once been held by Albert G. Brown, who withdrew from the US Senate in 1861.
The election of Revels was met with opposition from Southern conservative Democrats who cited the Dred Scott Decision which was considered by many to have been a central cause of the American Civil War. They argued that no black man was a citizen before the 14th Amendment was ratified in 1868. Because election to the Senate required nine years’ prior citizenship, opponents of Revels claimed he could not be seated, having been a citizen by law for only two years. Supporters of Revels countered by stating that the Dred Scott decision applied only to those blacks who were of pure African blood. Revels was of mixed black and white ancestry, and therefore exempt, they said, and had been a citizen all his life. This argument prevailed, and on February 25, 1870, Revels, by a vote of 48 to 8, became the first black man to be seated in the United States Senate.
