name the 2 federal laws that were passed to protect citizens from state laws that denied 14th and 15th amendment rights

The Fifteenth Amendment (Amendment XV) to the United States Constitution prohibits the federal government and each state from denying a citizen the right to vote based on that citizen's "race, color, or previous condition of servitude." It was ratified on February 3, 1870,[1] as the third and last of the Reconstruction Amendments. By 1869, amendments had been passed to abolish slavery and provide citizenship and equal protection under the laws, but the election of Ulysses S. Grant to the presidency in 1868 convinced a majority of Republicans that protecting the franchise of black male voters was important for the party's future. On February 26, 1869, after rejecting more sweeping versions of a suffrage amendment, Congress proposed a compromise amendment banning franchise restrictions on the basis of race, color, or previous servitude. After surviving a difficult ratification fight, the amendment was certified as duly ratified and part of the Constitution on March 30, 1870.
