The 15th Amendment to the United States Constitution was passed by Congress on February 26, 1869, and ratified by the states on February 3, 1870. It was officially included in the Constitution on March 30, 1870.
When the American Civil War concluded in 1867, it ushered the adoption of three new constitutional amendments. The 13th Amendment ended slavery, the 14th Amendment accorded citizenship to African-Americans and the 15th Amendment guaranteed African-American males the right to suffrage. The majority of abolitionists considered the 15th Amendment as the most significant right for the former slaves of America. However, racial discrimination was still prevalent even after the amendment was implemented. Some African-Americans, particularly in the South, were excluded from participating in the electoral process.
