of the American South which occurred after the war. The Thirteenth Amendment (proposed in 1864 and ratified in 1865) abolished slavery and involuntary servitude, except for those duly convicted of a crime. The Fourteenth Amendment (proposed in 1866 and ratified in 1868) addresses citizenship rights and equal protection of the laws for all persons. The Fifteenth Amendment (proposed in 1869 and ratified in 1870) prohibits discrimination in voting rights of citizens on the basis of "race, color, or previous condition of servitude." Males of all races, regardless of prior enslavement, could vote in some states of the early United States, such as New Jersey, provided that they could meet other requirements, such as property ownership. These amendments were intended to guarantee the freedom of the former slaves and grant certain civil rights to them and protect the former slaves and all citizens of the United States from discrimination. However, the promise of these amendments was eroded by state laws and federal court decisions throughout the late 19th century. They were not recognized until the Supreme Court decision in ''

Fourteenth Amendment

The Fourteenth Amendment to the United States Constitution was proposed by Congress on June 13, 1866. By July 9, 1868, it had received ratification by the legislatures of the required number of states in order to officially become the Fourteenth Amendment. On July 20, 1868, Secretary of State William Seward certified that it had been ratified and added to the federal Constitution. The amendment addresses citizenship rights and equal protection of the laws and was proposed in response to issues related to the treatment of

After rejecting broader versions of a suffrage amendment, Congress proposed a compromise amendment banning franchise restrictions on the basis of race, color, or previous servitude on February 26, 1869. The amendment survived a difficult ratification fight and was adopted on March 30, 1870. After blacks gained the vote, the

While white Democrats regained power in southern state legislatures, through the 1880s and early 1890s, numerous blacks continued to be elected to local offices in many states, as well as to Congress as late as 1894. Beginning around 1900, states in the former Confederacy passed new constitutions and other laws that incorporated methods to disenfranchise blacks, such as

The results in voter suppression were dramatic, as voter rolls fell: nearly all blacks, as well as tens of thousands of poor whites in Alabama and other states, were forced off the voter registration rolls and out of the political system, effectively excluding millions of people from representation. In the twentieth century, the Court interpreted the amendment more broadly, striking down grandfather clauses in '' Guinn v. United States'' (1915).

primaries were the only competitive contests in those states. But Southern states reacted rapidly to Supreme Court decisions, often devising new ways to continue to exclude blacks from voter rolls and voting; most blacks in the South did not gain the ability to vote until after the passage of the mid-1960s federal civil rights legislation and the beginning of federal oversight of voter registration and district boundaries. The Twenty-fourth Amendment (1964) forbade the requirement for poll taxes in federal elections; by this time five of the eleven southern states continued to require such taxes.
