Sesquicentennial, almost

Kharunya Paramaguru has a Time article about the end (finally) of the Civil War:

Here’s an outcome the producers of the movie Lincoln probably never expected: it indirectly led to the official ratification of the Thirteenth Amendment to ban slavery in Mississippi, nearly 150 years after its adoption.
The story began in November of last year, when Ranjan Batra, an associate professor at the University of Mississippi Medical Center, went to see director Steven Spielberg’s Oscar-nominated historical drama Lincoln, according to the Jackson, Mississippi newspaper, the Clarion-Ledger. Spielberg’s civics lesson tells the story of the final months of President Abraham Lincoln’s life and his efforts to get the Thirteenth Amendment to the Constitution passed by the House of Representatives.
After watching the film, Batra was curious to find out what happened to the Amendment once it was passed. It went on to be adopted in less than a year, when 27 of the then-36 states ratified it by the end of 1865. Mississippi was the last of these states to do so— they finally got around to it in 1995— but Batra spotted a curious detail next to the state’s name on the website usconstitution.net: the ratification was unofficial, as Mississippi never formally notified the U.S. archivist.
Batra mentioned the oversight to a friend, Ken Sullivan, who recalled the 1995 debate over the law and tracked down a copy of the resolution. It had been passedby the Mississippi Senate and House— unanimously, recalled the bill’s introcuder, Senator Hillman Frazier to the Clarion-Ledger— but inexplicably had never beensent to the Office of the Federal Register.
Once the paperwork was eventually filed, the state received notification on 7 Febrhary from the director of the Federal Register that it had officially ratified the Thirteenth Amendment, if 148 years late. “We finally got it right,” Frazier said to the newspaper.
