Preston Brooks was a Southern Congressman and a passionate advocate of Southern Rights. Charles Sumner was an ardent abolitionist who delivered an impassioned speech against the authors of the Kansas-Nebraska Act of 1856. He also ridiculed the speech impediment of one of the authors, Andrew Butler. Preston Brooks got angry because he was the nephew of Andrew Butler. Together with a friend, Brooks approached Sumner as the latter worked at his desk and started caning Sumner. Sumner collapsed in the aisle and Preston Brooks continued caning him until his cane broke. Southerners sent canes to Preston Brooks to replace the one he broke.
I know Columbus was one... Sorry, that's all I know.
The Haitian Revolution!
The Haitian Revolution began as a slave insurrection and culminated in the establishment of a sovereign state. The major insurgency began in 1791 in the important French colony of Saint-Domingue. In part inspired by the egalitarian ideology of the French Revolution, African slaves staged an organized revolt, murdering hundreds of whites and torching sugar plantations on their way to seizing control of Saint-northern Domingue's provinces. The disturbance would last until February 1794, when the French government declared the abolition of slavery in all of its domains.And when Napoleon Bonaparte's imperial soldiers seized Louverture in 1802 and sought to reintroduce slavery, the former slaves organized a resistance movement once again!
Amazing, right?
