Ulysses S. Grant (born Hiram Ulysses Grant; April 27, 1822 – July 23, 1885) was the 18th President of the United States (1869–77).
As Commanding General (1864–69), Grant worked closely with President Abraham Lincoln to lead the Union Army to victory over the Confederacy in the American Civil War. He implemented Congressional Reconstruction, often at odds with President Andrew Johnson. Twice elected president, Grant led the Republicans in their effort to remove the vestiges of Confederate nationalism and slavery, protect African American citizenship, and support economic prosperity. His presidency has often been criticized for tolerating corruption and for the severe economic depression in his second term.
