Fifteenth Amendment to the United States Constitution in the context of "40th United States Congress"

The Reconstruction Amendments, or the Civil War Amendments, are the Thirteenth, Fourteenth, and Fifteenth amendments to the United States Constitution, adopted between 1865 and 1870. The amendments were a part of the implementation of the Reconstruction of the American South which occurred after the Civil 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."

The Civil Rights Act of 1964 (Pub. L. 88–352, 78 Stat. 241, enacted July 2, 1964) is a landmark civil rights and labor law in the United States that outlaws discrimination based on race, color, religion, sex, and national origin. It prohibits unequal application of voter registration requirements, racial segregation in schools and public accommodations, and employment discrimination. The act "remains one of the most significant legislative achievements in American history".

Initially, powers given to enforce the act were weak, but these were supplemented during later years. Congress asserted its authority to legislate under several different parts of the United States Constitution, principally its enumerated power to regulate interstate commerce under the Commerce Clause of Article I, Section 8, its duty to guarantee all citizens equal protection of the laws under the 14th Amendment, and its duty to protect voting rights under the 15th Amendment.

The Voting Rights Act of 1965 is a landmark U.S. federal statute that prohibits racial discrimination in voting. It was signed into law by President Lyndon B. Johnson during the height of the civil rights movement on August 6, 1965. Congress later amended the Act five times to expand its protections. Designed to enforce voting rights protected by the Fourteenth and Fifteenth Amendments to the United States Constitution, the Act sought to secure the right to vote for racial minorities throughout the country, especially in the South. According to the U.S. Department of Justice, the Act is considered to be the most effective piece of federal civil rights legislation ever enacted. The National Archives and Records Administration stated: "The Voting Rights Act of 1965 was the most significant statutory change in the relationship between the federal and state governments in the area of voting since the Reconstruction period after the Civil War".

The act contains numerous provisions that regulate elections. Its "general provisions" provide nationwide protections for voting rights. Section 2 is a general provision that prohibits state and local government from imposing any rule that "results in the denial or abridgement of the right of any citizen to vote on account of race or color" or membership in a language minority group. Other provisions outlaw literacy tests and similar devices that were historically used to disenfranchise racial minorities. The act also contains "special provisions" that apply only to certain jurisdictions. A core special provision is the Section 5 preclearance requirement, which prohibits certain jurisdictions from implementing any change affecting voting without first receiving confirmation from the U.S. attorney general or the U.S. District Court for D.C. that the change does not discriminate against protected minorities. Another special provision requires jurisdictions containing significant language minority populations to provide bilingual ballots and other election materials.

Voting rights, specifically enfranchisement and disenfranchisement of different groups, have been a moral and political issue throughout United States history.

Eligibility to vote in the United States is governed by the United States Constitution and by federal and state laws. Several constitutional amendments (the Fifteenth, Nineteenth, and Twenty-sixth specifically) require that voting rights of U.S. citizens cannot be abridged on account of race, color, previous condition of servitude, sex, or age (18 and older); the constitution as originally written did not establish any such rights during 1787–1870, except that if a state permitted a person to vote for the "most numerous branch" of its state legislature, it was required to permit that person to vote in elections for members of the United States House of Representatives. In the absence of a specific federal law or constitutional provision, each state is given considerable discretion to establish qualifications for suffrage and candidacy within its own respective jurisdiction; in addition, states and lower level jurisdictions establish election systems, such as at-large or single member district elections for county councils or school boards. Thus, the enfranchisement or disenfranchisement in one state may be stricter or more lenient than in another state. Beyond qualifications for suffrage, rules and regulations concerning voting (such as the poll tax) have been contested since the advent of Jim Crow laws and related provisions that indirectly disenfranchised racial minorities.

Disfranchisement after the Reconstruction era in the United States, especially in the Southern United States, was based on a series of laws, new constitutions, and practices in the South that were deliberately used to prevent black citizens from registering to vote and voting. These measures were enacted by the former Confederate states following the end of the Reconstruction era in the late 19th century. Efforts were also made in Maryland, Kentucky, and Oklahoma. Their actions were designed to thwart the objective of the Fifteenth Amendment to the United States Constitution, ratified in 1870, which prohibited states from depriving voters of their voting rights based on race. The laws were frequently written in ways to be ostensibly non-racial on paper (and thus not violate the Fifteenth Amendment), but were implemented in ways that selectively suppressed black voters apart from other voters.

In the 1870s, white racists had used violence by domestic terrorism groups (such as the Ku Klux Klan), as well as fraud, to suppress black voters. After regaining control of the state legislatures, Southern Democrats were alarmed by a late 19th-century alliance between Republicans and Populists that cost them some elections. After achieving control of state legislatures, white conservatives added to previous efforts and achieved widespread disfranchisement by law: from 1890 to 1908, Southern state legislatures passed new constitutions, constitutional amendments, and laws that made voter registration and voting more difficult, especially when administered by white staff in a discriminatory way. They succeeded in disenfranchising most of the black citizens, as well as many Poor Whites in the South, and voter rolls dropped dramatically in each state. The Republican Party was nearly eliminated in the region for decades, and the Southern Democrats established one-party control throughout the Southern United States.

The Redeemers were a political coalition in the Southern United States during the Reconstruction Era that followed the American Civil War. Redeemers were the Southern wing of the Democratic Party. They sought to regain their political power and enforce white supremacy. Their policy of Redemption was intended to oust the Radical Republicans, a coalition of freedmen, "carpetbaggers", and "scalawags". They were typically led by White yeomen and dominated Southern politics in most areas from the 1870s to 1910.

During Reconstruction, the South was under occupation by federal forces, and Southern state governments were dominated by Republicans, elected largely by freedmen and allies. Republicans nationally pressed for the granting of political rights to the newly freed slaves as the key to their becoming full citizens and the votes they would cast for the party. The Thirteenth Amendment (banning slavery), Fourteenth Amendment (guaranteeing the civil rights of former slaves and ensuring equal protection of the laws), and Fifteenth Amendment (prohibiting the denial of the right to vote on grounds of race, color, or previous condition of servitude), enshrined such political rights in the Constitution.
