Ulysses S. Grant was an American military officer, politician, and the 18th president of the United States from 1869 to 1877. As commanding general, Grant led the Union Army to victory in the American Civil War in 1865 and briefly served as U.S. secretary of war. An effective civil rights executive, Grant signed a bill to create the Justice Department and worked with Radical Republicans to protect African Americans during Reconstruction.
