The Reconstruction Amendments are the Thirteenth, Fourteenth, and Fifteenth amendments to the United States Constitution, adopted between 1865 and 1870, the five years immediately following the Civil War. The last time the Constitution had been amended was with the Twelfth Amendment more than 60 years earlier in 1804. The Reconstruction amendments were important in implementing the Reconstruction of the American South after the war. Their proponents saw them as transforming the United States from a country that was (in Abraham Lincoln's words) "half slave and half free" to one in which the constitutionally guaranteed "blessings of liberty" would be extended to the entire populace, including the former slaves and their descendants.
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". All races, regardless of prior slavery, 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 freedom to former slaves and to establish and prevent discrimination in certain civil rights to former slaves and all citizens of the United States. The promise of these amendments was eroded by state laws and federal court decisions throughout the late 19th century. In 1876 and later, some states passed Jim Crow laws that limited the rights of African-Americans. Important Supreme Court decisions that undermined these amendments were the Slaughter-House Cases in 1873, which prevented rights guaranteed under the Fourteenth Amendment's privileges or immunities clause from being extended to rights under state law; and Plessy v. Ferguson in 1896 which originated the phrase "separate but equal" and gave federal approval to Jim Crow laws. The full benefits of the Thirteenth, Fourteenth, and Fifteenth amendments were not realized until the Supreme Court decision in Brown v. Board of Education in 1954 and laws such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965.
The Thirteenth Amendment to the United States Constitution abolished slavery and involuntary servitude, except as punishment for a crime. It was passed by the U.S. Senate on April 8, 1864, and, after one unsuccessful vote and extensive legislative maneuvering by the Lincoln administration, the House followed suit on January 31, 1865. The measure was swiftly ratified by all but three Union states (the exceptions were Delaware, New Jersey, and Kentucky), and by a sufficient number of border and "reconstructed" Southern states, to be ratified by December 6, 1865. On December 18, 1865, Secretary of State William H. Seward proclaimed it to have been incorporated into the federal Constitution. It became part of the Constitution 61 years after the Twelfth Amendment, the longest interval between constitutional amendments to date.
Slavery had been tacitly enshrined in the original Constitution through provisions such as Article I, Section 2, Clause 3, commonly known as the Three-Fifths Compromise, which detailed how each state's total slave population would be factored into its total population count for the purposes of apportioning seats in the United States House of Representatives and direct taxes among the states. Although many slaves had been declared free by Lincoln's 1863 Emancipation Proclamation, their legal status after the Civil War was uncertain.
The Fourteenth Amendment to the United States Constitution was proposed by Congress on June 14, 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 treatment of freedmen following the war. The amendment was bitterly contested, particularly by Southern states, which were forced to ratify it in order to return their delegations to Congress. The Fourteenth Amendment, particularly its first section, is one of the most litigated parts of the Constitution, forming the basis for landmark decisions such as Roe v. Wade (1973), regarding abortion, and Bush v. Gore (2000), regarding the 2000 presidential election.
The second, third, and fourth sections of the amendment are seldom, if ever, litigated. The fifth section gives Congress enforcement power. The amendment's first section includes several clauses: the Citizenship Clause, the Privileges or Immunities Clause, the Due Process Clause, and the Equal Protection Clause. The Citizenship Clause provides a broad definition of citizenship, overruling the Supreme Court's decision in Dred Scott v. Sandford (1857), which had held that Americans descended from Africans could not be citizens of the United States. The Privileges or Immunities Clause has been interpreted in such a way that it does very little. While "Section 2 of the Fourteenth Amendment reduces congressional representation for states that deny suffrage on racial grounds," it was not enforced after southern states disfranchised blacks in the late 19th and early 20th centuries (see below, at Fifteenth Amendment). While Northern Congressmen in 1900 raised objections to the inequities of southern states being apportioned seats based on total populations when they excluded blacks, Southern Democratic Party representatives formed such a powerful bloc that opponents could not gain approval for change of apportionment.
The Due Process Clause prohibits state and local government officials from depriving persons of life, liberty, or property without legislative authorization. This clause has also been used by the federal judiciary to make most of the Bill of Rights applicable to the states, as well as to recognize substantive and procedural requirements that state laws must satisfy.
The Equal Protection Clause requires each state to provide equal protection under the law to all people within its jurisdiction. This clause was the basis for the US Supreme Court's ruling in Brown v. Board of Education (1954), that racial segregation in public schools was unconstitutional, and its prohibition of laws against interracial marriage, in its ruling in Loving v. Virginia (1967).
This amendment was the foundation of elements of the Civil Rights Act of 1964 and the Voting Rights Act of 1965 (this also relied on the 15th Amendment), legislation to end legal segregation in the states and to provide for oversight and enforcement by the federal government of citizens' rights to vote without discrimination. It has also been referred to for many other court decisions rejecting unnecessary discrimination against people belonging to various groups.
The Fifteenth Amendment to the United States Constitution prohibits the federal and state governments 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, 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 narrow election of Ulysses S. Grant to the presidency in 1868 convinced a majority of Republicans that protecting the franchise of black voters was important for the party's future. 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 Ku Klux Klan directed some of their attacks to disrupt their political meetings and intimidate them at the polls, to suppress black participation. In the mid-1870s, there was a rise in new insurgent groups, such as the Red Shirts and White League, who acted on behalf of the Democratic Party to violently suppress black voting. 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.
From 1890 to 1910, all the states of the former Confederacy passed new constitutions and other laws that incorporated methods to disfranchise blacks, such as poll taxes, residency rules, and literacy tests administered by white staff, sometimes with exemptions for whites via grandfather clauses. When challenges reached the Supreme Court, it interpreted the amendment narrowly, ruling based on the stated intent of the laws rather than their practical effect. 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. Democratic state legislatures passed racial segregation laws for public facilities and other types of Jim Crow restrictions. During this period of political struggle, the rate of lynchings in the South reached an all-time high.
In the twentieth century, the Court interpreted the amendment more broadly, striking down grandfather clauses in Guinn v. United States (1915). It took a quarter century to finally dismantle the white primary system in the "Texas primary cases" (1927–1953). With the South having become a one-party region after the disfranchisement of blacks, Democratic Party 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 passage of the mid-1960s federal civil rights legislation and 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. Together with the U.S. Supreme Court ruling in Harper v. Virginia State Board of Elections (1966), which forbade requiring poll taxes in state elections, blacks regained the opportunity to participate in the U.S. political system.
