1837

Senator John C. Calhoun of South Carolina delivered a Senate speech on February 6, 1837, declaring slavery 'a good — a positive good.' This marked an explicit shift from the earlier apologetic framing of slavery as a 'necessary evil.' Calhoun argued slavery was the foundation of republican liberty for white men, beneficial to the enslaved (whom he called 'primitive' people civilized through bondage), and the basis of Southern civilization. This ideology — developed by Calhoun, Thomas Dew, George Fitzhugh, and others — became dominant in the antebellum South. It shaped education, churches, and politics, making compromise increasingly impossible by reframing slavery as a virtue to be expanded rather than a problem to be contained.

Elijah Lovejoy, a Presbyterian minister and abolitionist newspaper editor in Alton, Illinois, was shot and killed by a pro-slavery mob that had attacked his warehouse and destroyed his printing press for the fourth time. Lovejoy had previously been driven from St. Louis for antislavery writing. His murder in a free state shocked the North and dramatically accelerated abolitionist sentiment. A young Abraham Lincoln cited Lovejoy's murder in an 1838 speech about mob violence. Lovejoy's death transformed many moderate antislavery Northerners into committed abolitionists.

Printer and abolitionist minister Elijah Lovejoy is shot and killed by a pro-slavery mob in Alton, Illinois on November 7, 1837, while defending his printing press. Lovejoy's press had been destroyed three times. His murder on free soil shocks the North and drives thousands to abolitionism, including a young Abraham Lincoln, who cites it years later.
