Rutherford B. Hayes
Republican Rutherford B. Hayes, previously a Union soldier, as well as a representative and governor of Ohio, is publicly sworn in as the nineteenth President of the United States. He takes the oath privately on March 3rd. In the race against Democrat Samuel Tilden, Hayes secures only 48 percent of the popular vote and 164 electoral votes to Tilden's 184. However, voter fraud and unclear results are reported in several states. A controversial decision of a special electoral commission ultimately proclaims Hayes President, with some Democrats referring to Hayes as “Rutherfraud.” In return for the presidency, the Republicans make various concessions, including the removal of federal troops from the South. These actions are labeled the “Compromise of 1877”; African-Americans refer to it as “The Great Betrayal.” March 05, 1877
