This bold step into the latter third of the 19th Century was declared official by the National Archivist on February 7. Of this year. As in, precisely two weeks ago:
On Feb. 7, Charles A. Barth, director of the Federal Register, wrote back that he had received the resolution: “With this action, the State of Mississippi has ratified the 13th Amendment to the Constitution of the United States.”
The delay was apparently due to a clerical error, as the state legislature ratified the Amendment in 1995 yet the paperwork was not formally submitted to the United States Archivist. But still, 1995?
In all fairness, my current state of residence, Oregon, didn’t get around to ratifying the Fifteenth Amendment until 1959, and waited until 1973 to ratify the Fourteenth. At least Oregon ratified the Thirteenth 130 to 148 years prior to Mississippi, depending on how one measures these things.
