I've recently been learning about Grant and he has quickly become one of my favorite figures in history. I've already know (a lot) about his military achievements and his ability as a commander and I think he was the best general of the Civil War.

But I'm not curious about his ability as a commander, but as a president.

I've heard that Grant was one of the worst presidents in US history with a corrupt cabinet and inefficient way of governing. However, the more I learned about what he did in office the more the claims that he was corrupt and not a good president just becomes moot. I mean the dude literally had the 15th amendment signed and even crushed the Ku Klux Klan so hard that they didn't come back until the 1920s.

However, I'm not sure about his other achievements, nor on how actually involved he was in the corruption scandals. I feel like there's just a lot a more I just don't know about his time in presidency.

So does Grant really deserve the reputation of the corrupt, drunkard president or was he really much better than the narrative suggests? What were some of his other achievements?
