Hundreds of historians and biographers have written biographies and historical accounts about the life of Ulysses S. Grant and his performance in military and presidential affairs. Very few presidential reputations have shifted as dramatically as Grant's.
From the time Grant was hailed across the North as the winning general in the American Civil War his military reputation has held up fairly well. He was roundly credited as the General who "saved the Union," and although he has been the subject of some criticism over the years, this reputation largely stands intact. His presidential reputation has not always fared so well. Although his nomination as president of the United States in 1868 was considered "a foregone conclusion" and he easily won the election, his reputation as president began to suffer from congressional investigations into corruption in his administration. However, his reputation has improved in the 21st century, for his prosecution of the Ku Klux Klan and for his protection and legal support of African Americans. He is also recognized for the creation of the first Civil Service Commission, and appointment of cabinet reformers, who prosecuted the Whiskey Ring.
After leaving office in 1877, Grant's reputation soared during his well-publicized diplomatic world tour. Accusations of Grant's alleged excessive drinking hounded him for most of his military and political career, and are still widely believed by the general public. Historians generally agree he drank occasionally but not often. At his death, he was seen as "a symbol of the American national identity and memory",[1] when millions turned out for his funeral procession in 1885.
