Regarding the ratification of the 15th amendment to the US Constitution:
UPDATED ON FEB 21, 2019
1870
15th Amendment adopted
Following its ratification by the requisite three-fourths of the states, the 15th Amendment, granting African-American men the right to vote, is formally adopted into the U.S. Constitution. Passed by Congress the year before, the amendment reads, “the right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of race, color, or previous condition of servitude.” One day after it was adopted, Thomas Peterson-Mundy of Perth Amboy, New Jersey, became the first African American to vote under the authority of the 15th Amendment.
In 1867, the Republican-dominated Congress passed the First Reconstruction Act, over President Andrew Johnson’s veto, dividing the South into five military districts and outlining how new governments based on universal manhood suffrage were to be established. With the adoption of the 15th Amendment in 1870, a politically mobilized African-American community joined with white allies in the Southern states to elect the Republican Party to power, which brought about radical changes across the South. By late 1870, all the former Confederate states had been readmitted to the Union, and most were controlled by the Republican Party, thanks to the support of African-American voters.
