In 1814, on this day Northern Democrat Congressman David Wilmot was born in Bethany, Pennsylvania.
39th Parallel Part 1:
Wilmot Proviso leads to warA leading Free Soiler, he was the architect of the Wilmot Proviso which opposed the extension of slavery into the occupied territories of Mexico. The legislation passes the House of Representatives, but was defeated in the Senate under the recently introduced two-thirds majority rule.
That rule had been demanded by Southern Senators as a precondition for admitting Baja California, Chihuahua, Sonora, Coahuilia and Tamaulipas into the Union as new states. Otherwise Dixie politicians would have been outnumbered in the Upper House, and an insurmountable challenge to end the institution of slavery would soon arise.
In point of fact Wilmot was not an abolitionist, rather he had economic objections to Free Labor. But it made no difference, his Free Soil challenge was enough to put the newly enlarged Union on the road to Civil War. An installment from 39th Parallel thread.
