"While Grant's views on slavery evolved over time, his relationship with slavery was complicated and demonstrates the pervasiveness of the institution in antebellum America. Grant's father, Jesse, was an abolitionist who wrote for the Castigator, a newspaper in Ohio. However, his son's attitudes toward slavery were more ambivalent, at least from what we can discern of his opinions before and during the Civil War. "I never was an abolitionist, Grant wrote to his friend and patron, Elihu Washburne, in 1863, "not even what could be called anti-slavery…"
Grant may have been initially ambivalent to the institution of slavery but his wartime experiences showed him that it was morally and practically indefensible and that African Americans would not only make strong allies in defeating the Confederates, but
respected citizens in the reunited nation to follow. As the 18th President of the reunited nation, he was an advocate and defender of the freedmen's newly acquired rights, earning the admiration of Frederick Douglas, who believed, "To Grant more than any other man the Negro owes his enfranchisement."
Novelist
Hamlin Garland, an early biographer who spoke with Grant's Missouri neighbors, wrote,
"The use of slaves on the farm…was a source of irritation and shame to Grant. Jefferson Sapington told me that he and Grant used to work in the fields with the blacks. He said with glee, 'Grant was helpless when it came to making slaves work,' and Mrs. Boggs corroborated this. 'He was no hand to manage negroes,'she said. 'He couldn't force them to do anything. He wouldn't whip them. He was too gentle and good tempered and besides he was not a slavery man.'"
There is no dispute over an element of ambivalence here which goes to the "pervasiveness of the institution in antebellum America."
And an evolving of attitudes, including Grant's.
