The Voting Rights Act of 1965: What It Did, How It Worked, and What Changed

Short answer

• The Voting Rights Act of 1965 is a federal law, signed by President Lyndon B. Johnson on August 6, 1965, that enforced the Fifteenth Amendment by banning racial discrimination in voting. Its best known tools were a nationwide ban on denying or abridging the right to vote on account of race or color, a suspension of literacy tests and similar devices in covered places, federal examiners and observers where registration lagged, and a preclearance rule that required certain jurisdictions with a history of discrimination to get federal approval before changing a voting rule. Congress later amended the Act several times, including in 1975, when it added protections for language minority groups, and in 1982, when it changed the test for a Section 2 violation. The Supreme Court upheld the original Act in 1966, but later decisions narrowed parts of it. In 2013, the Court struck down the coverage formula that decided which places had to seek preclearance, so general preclearance under Section 5 no longer operates unless Congress enacts a new formula. Section 2, the nationwide ban, remains in force, although its scope in redistricting cases was substantially reinterpreted in 2026. This article is general legal information only. It is not legal advice for any person's situation, and it does not describe current registration rules, deadlines, or eligibility rules in any state. Those rules are set by state and local election officials, and they change. ---

What the Act Was For

The Act begins with its purpose in plain terms: to enforce the Fifteenth Amendment. That amendment, ratified on February 3, 1870, says that 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. It also gives Congress the power to enforce the amendment by appropriate legislation.

The gap between that text and practice is the central story of the Act. After Reconstruction ended, many Southern states adopted rules that did not mention race on their face but kept Black citizens from registering and voting in practice. Literacy tests required a prospective voter to read, write, or explain a passage, often at the discretion of a local registrar. Poll taxes required payment of a fee before voting. Grandfather clauses excused a voter from a test or tax if an ancestor had voted before a set date, a date chosen before Black men could vote in most of the South. White primaries excluded Black voters from party primaries that, in one party states, effectively decided the election. Alongside those formal rules, many Black citizens faced intimidation, economic retaliation, and violence when they tried to register.

Earlier federal laws had not solved the problem. The Civil Rights Acts of 1957, 1960, and 1964 included voting provisions, but enforcement depended heavily on case by case lawsuits. The Department of Justice later explained the weakness of that approach: as soon as one discriminatory practice was stopped, a new one could be substituted, and litigation had to start again. Supporters argued that this cycle showed why Congress needed a law that acted before a discriminatory change took effect, at least in places with a record of discrimination. Critics argued that election administration was primarily a state responsibility. That tension runs through the whole history of the Act.

Selma and the Passage of the Act

The immediate push for the Act came from the voting rights campaign in Selma, Alabama, in early 1965. Activists from the Dallas County Voters League, the Student Nonviolent Coordinating Committee, and the Southern Christian Leadership Conference organized registration drives and marches to protest the denial of voting rights to Black citizens in Dallas County.

On March 7, 1965, marchers walking from Selma to Montgomery were met by Alabama state troopers at the Edmund Pettus Bridge and attacked. The day became known as Bloody Sunday. John Lewis, then a leader in the Student Nonviolent Coordinating Committee, was among those injured. National Archives material records Lewis recounting that he was struck with a nightstick, fell, was struck again when he tried to rise, and was treated for a fractured skull.

President Johnson addressed a joint session of Congress on March 15, 1965, and called for voting rights legislation. The administration proposal was introduced in the House as H.R. 6400 on March 17, 1965, and in the Senate as S. 1564 on March 18, 1965. After debate, the House approved the conference report by 328 votes to 74 on August 3, and the Senate approved it by 79 votes to 18 on August 4. President Johnson signed the Act on August 6, 1965, with civil rights leaders present, including Martin Luther King Jr. and Rosa Parks.

The Act did not create the right to vote from nothing. It enforced a constitutional right that, supporters argued, had been denied in practice for nearly a century. Later cases turned less on whether racial discrimination in voting was wrong than on what tools Congress could use, how far they could reach, and for how long.

The Original Act, Section by Section

The 1965 Act combined a nationwide rule with special rules for places with the worst record. The two kinds of provisions must be separated, because later amendments and court decisions affected them differently.

Section 2: the nationwide ban

Section 2 closely followed the Fifteenth Amendment. It prohibited any voting qualification, prerequisite, standard, practice, or procedure imposed by a state or political subdivision that denied or abridged the right to vote on account of race or color. Because it applied nationwide, it did not depend on coverage under the special provisions. A voter, a group of voters, or the Attorney General could bring a case under Section 2 in federal court.

In its original form, Section 2 was most often read as a ban on practices that denied access to the ballot, such as a discriminatory registration rule. Over time, it also became the main tool for challenging vote dilution, which differs from outright denial. Vote dilution means minority voters can cast ballots, but district lines or election structures weaken their ability to elect candidates of their choice. Cracking splits a minority community across several districts so it cannot form a majority in any of them. Packing concentrates minority voters in a small number of districts so their influence elsewhere is reduced.

Sections 4 and 5: coverage and preclearance

Sections 4 and 5 were the Act’s special provisions, temporary by design. Section 4(b) set a coverage formula. In general, a jurisdiction was covered if it had used a test or device, such as a literacy test, on November 1, 1964, and if fewer than 50 percent of its voting age residents were registered or voted in the 1964 presidential election. The formula was not a list of states chosen by name. It was a test that produced a list, including whole states and individual counties elsewhere.

Section 5 then required a covered jurisdiction to obtain preclearance before putting any change affecting voting into effect, meaning approval from the Attorney General or from the United States District Court for the District of Columbia. The change could be a registration rule, a polling place, district boundaries, or a method of election. The jurisdiction had to show that the change did not have a discriminatory purpose and would not have a discriminatory effect. The point was prevention: a discriminatory change would be stopped before an election, not challenged after voters had been harmed. The special provisions were set to expire after five years.

Tests, examiners, and observers

In covered jurisdictions, the Act suspended literacy tests and similar devices. The Department of Justice suspended literacy tests and other discriminatory measures in seven states on August 7, 1965, and federal examiners were assigned in the South within days.

Federal examiners could add eligible voters to the rolls directly, bypassing a local registrar who had refused them. Federal observers could watch activities inside polling places where an examiner was serving. Examiners registered voters, observers watched elections. Both tools were tied to coverage, so their reach changed when coverage changed.

The Act also included two safety valves. A covered jurisdiction could bail out by showing, in court, that it had complied with the Act and had not used a discriminatory test or device for a set period; bailout was liberalized in 1982. Separately, Section 3(c) allowed a federal court, after finding a violation, to order a noncovered jurisdiction to seek preclearance for a set period, often called bail in. After 2013, court ordered preclearance under Section 3(c) became the only route to required preclearance, according to Department of Justice guidance.

What the Act did not do about poll taxes

A common misunderstanding is that the 1965 Act itself banned poll taxes outright. It did not include a direct nationwide ban. Instead, it directed the Attorney General to challenge poll taxes. The operative bans came from elsewhere: the Twenty Fourth Amendment, ratified in 1964, barred poll taxes in federal elections, and in Harper v. Virginia State Board of Elections in 1966, the Supreme Court held that Virginia’s poll tax violated the Fourteenth Amendment, effectively ending poll taxes in state elections as well.

The Immediate Effect

The effect on registration was fast and large, and it is one of the least disputed parts of the Act’s history. The Congressional Research Service reported that nearly one million Black voters were registered within four years of passage, and that more than 50 percent of the Black voting age population was registered in every Southern state within that period.

State figures show the same pattern. The Economic Policy Institute chart, crediting the U.S. Commission on Civil Rights 2018, adapted from Maye 2022, gives March 1965 and September 1967 figures: Mississippi, 6.7 percent to 59.8 percent; Alabama, 19.3 percent to 51.6 percent; Georgia, 27.4 percent to 52.6 percent; Louisiana, 31.6 percent to 58.9 percent. Across covered jurisdictions, the Black registered share rose from 29.3 percent in 1965 to 52.1 percent in 1967.

Registration alone did not end discrimination. Local officials adopted new methods, including at large elections and redrawn districts, that reduced the ability of newly registered Black voters to elect candidates of their choice. That shift, from blocking registration to diluting votes, is why Section 2 litigation and later amendments became so important.

Amendments and Reauthorizations

Congress amended the Act in 1970, 1975, 1982, 1992, and 2006. Each amendment, except for 1992, extended the special provisions tied to the coverage formula, for five years in 1970, seven years in 1975, and 25 years in both 1982 and 2006.

The 1970 amendments extended Section 5 for five years, added 1968 election data to the coverage formula, and suspended literacy tests nationwide. The nationwide suspension mattered because it removed the need to tie the test suspension to coverage.

The 1975 amendments were the largest expansion of who the Act protected. Congress extended Section 5 for seven years, made the nationwide literacy test ban permanent, added 1972 election data to the coverage formula, and expanded protection to language minority groups: American Indians, Asian Americans, Alaskan Natives, and people of Spanish heritage. Section 4(f)(4) brought into coverage a jurisdiction that had provided materials only in English in 1972, where a single language minority group made up more than five percent of voting age citizens and turnout or registration was below 50 percent. Section 203 required a covered jurisdiction to provide voting materials, including ballots, in the applicable minority language as well as in English, where the group met a population and literacy test, generally more than five percent or more than 10,000 limited-English-proficient voting age citizens, with a higher illiteracy rate than the national rate.

The 1982 amendments extended the special provisions for 25 years, liberalized bailout, and amended Section 2, as explained in the court section below. The 1992 amendments extended the bilingual voting assistance provisions for another 15 years, without extending the Section 5 coverage provisions in the same way. The 2006 amendments, formally the Fannie Lou Hamer, Rosa Parks, and Coretta Scott King Voting Rights Act Reauthorization and Amendments Act of 2006, extended Section 5 and other temporary provisions for another 25 years. The House approved the 2006 reauthorization by 390 votes to 33, and the Senate approved it by 98 votes to 0, according to the Congressional Research Service summary. The 2006 law did not update the Section 4(b) coverage formula. That choice became central in 2013, when the Supreme Court held that the old formula could no longer support preclearance.

The Supreme Court and the Act

South Carolina v. Katzenbach, 1966

South Carolina challenged the Act almost immediately, arguing that the coverage formula and preclearance violated federalism, equal protection, due process, and separation of powers. In South Carolina v. Katzenbach in 1966, the Supreme Court upheld the Act, holding that Congress had power under the Fifteenth Amendment to use strong remedies against a long history of voting discrimination, and that the formula was rational on the record before Congress. The decision did not hold that preclearance would be valid forever.

Mobile v. Bolden and the 1982 results test

In 1980, in City of Mobile v. Bolden, a plurality of the Supreme Court held that a violation of the Fifteenth Amendment, and of Section 2 as then written, required proof of discriminatory intent. A discriminatory effect, without proof that a practice was adopted because of race, was not enough. The case concerned at large elections in Mobile, Alabama, which critics argued diluted Black voting strength even though Black citizens could register and vote.

Congress disagreed with that reading. In the 1982 amendments, Congress rewrote Section 2 so a violation could be established if, based on the totality of circumstances, members of a protected class had less opportunity than other members of the electorate to participate and to elect representatives of their choice. Proof of intent was no longer required. Congress also stated that nothing in Section 2 established a right to proportional representation.

Thornburg v. Gingles, 1986

In Thornburg v. Gingles in 1986, the Supreme Court set out a framework for Section 2 redistricting claims. A challenger generally had to show three preconditions: the minority group was large and compact enough to form a majority in a reasonably drawn district, the group was politically cohesive, and the white majority voted as a bloc enough to usually defeat the group’s preferred candidate. A court then examined the totality of circumstances, including history of discrimination and polarized voting. Gingles governed redistricting cases for nearly four decades, until later decisions, especially in 2026, reworked it.

Shelby County v. Holder, 2013

In Shelby County v. Holder, decided on June 25, 2013, by a vote of 5 to 4, the Supreme Court held that Section 4(b), the coverage formula, was unconstitutional. Chief Justice John Roberts wrote for the majority that the formula was based on data more than 40 years old and no longer responded to current conditions, and that it imposed an impermissible burden on the equal sovereignty of the states. The Court did not strike down Section 5 itself, and it did not hold that preclearance as a concept was unconstitutional. But without a valid coverage formula, Section 5 had no list of jurisdictions to apply to, so general preclearance stopped operating.

The dissent, written by Justice Ruth Bader Ginsburg, argued that preclearance had worked precisely because it deterred discrimination, and that throwing out the formula when the Act had succeeded was like throwing away an umbrella in a rainstorm because you were not getting wet. Supporters argued that the South of 2013 was not the South of 1965 and that states should not be singled out indefinitely on decades old conduct. Critics argued that the decision removed the preventive tool just as new voting rules were being adopted in formerly covered states. Effects on polling places, early voting, and identification rules after 2013 are disputed and vary by state, so no single national effect figure is presented as settled.

Brnovich v. Democratic National Committee, 2021

In Brnovich v. Democratic National Committee on July 1, 2021, by a vote of 6 to 3, the Supreme Court addressed Section 2 outside redistricting. The case concerned two Arizona rules: ballots cast out of precinct were not counted, and third party ballot collection was restricted, with exceptions for family members, household members, caregivers, mail carriers, and election officials. The Court held that neither rule violated Section 2, and that the ballot collection law was not enacted with a discriminatory purpose.

The majority, written by Justice Samuel Alito, held that Section 2 required voting to be equally open to minority and nonminority voters, judged by the totality of circumstances, and it identified guideposts, including the size of the burden, departure from standard practice as of 1982, disparity in impact, opportunities in the state’s system as a whole, and the state’s interests. The dissent, written by Justice Elena Kagan, argued that the reading weakened Section 2 by treating small burdens as acceptable even when they fell more heavily on minority voters. Supporters argued that Section 2 was not meant to invalidate every rule with a disparate impact. Critics argued that the guideposts made Section 2 challenges much harder to win.

Allen v. Milligan, 2023

In Allen v. Milligan on June 8, 2023, the Supreme Court affirmed lower court rulings that Alabama’s congressional map likely violated Section 2. Alabama had drawn only one majority Black district out of seven, although Black voters made up about 27 percent of total population (25.9 percent of voting-age population), according to the challengers’ account summarized by the Congressional Research Service. The Court reaffirmed Gingles and the constitutionality of Section 2 as construed in Gingles. Alabama therefore had to draw a second district in which Black voters had an opportunity to elect a candidate of their choice.

Louisiana v. Callais, 2026

In Louisiana v. Callais on April 29, 2026, by a vote of 6 to 3, the Supreme Court substantially reworked that framework. Louisiana, after earlier Section 2 litigation, had drawn a second majority Black district. Voters challenged it as an unconstitutional racial gerrymander under the Fourteenth Amendment. The Court, in an opinion by Justice Samuel Alito, held that Section 2 did not require the second district, so no compelling interest justified the state’s use of race, and the district was an unconstitutional racial gerrymander.

The opinion also changed how future Section 2 claims are proved, according to the Brennan Center summary. It required plaintiffs’ illustrative maps to satisfy a jurisdiction’s political objectives, including protecting incumbents. It required a showing that racial bloc voting could not be explained by partisan affiliation. And in the totality of circumstances stage, it required strong evidence of present day intentional racial discrimination, giving much less weight to older discrimination and to disparities described as effects of societal discrimination. The dissent, written by Justice Kagan, argued that the majority had made a nullity of Section 2, in the phrase reported by the Virginia Law Weekly summary. The full consequences of Callais are still being litigated and debated. Callais did not strike down the text of Section 2, but it made redistricting claims substantially harder to win than under Milligan and Gingles.

What Remains in Force Today

As of October 2026, the Act is best described as changed, not repealed. Section 2 remains a nationwide ban, judged under the tests above, including the Callais revisions for redistricting. Section 203 continues to require covered jurisdictions to provide materials and assistance in the applicable minority language as well as in English. Section 3(c) continues to allow a court, after finding a violation, to order preclearance for a set period.

What does not operate generally is Section 5 preclearance under the old coverage formula. Section 5 remains in the statute book, but, in the words of the Department of Justice guidance, no jurisdictions are currently covered by Section 5 under Section 4(b), and previously covered jurisdictions do not need to seek preclearance unless Congress enacts a new formula or a court orders preclearance under Section 3(c). No new general formula had been enacted as of the date of this article. Private lawsuits and Department of Justice enforcement under Section 2 and Section 203 continue to be the main enforcement routes.

Frequently Asked Questions

What did the Voting Rights Act of 1965 actually ban?

It banned, nationwide, any voting rule that denied or abridged the right to vote on account of race or color, under Section 2. In covered places, it also suspended literacy tests, allowed federal examiners and observers, and required preclearance under Section 5. Later amendments added language minority protections and changed the Section 2 test.

Did the Act give Black Americans the right to vote?

Not in the sense of creating a new constitutional right. The Fifteenth Amendment, ratified in 1870, already prohibited denying the vote on account of race, color, or previous condition of servitude. The Act provided enforcement tools earlier laws lacked. Women faced a separate barrier until the Nineteenth Amendment, ratified in 1920, prohibited denying the vote on account of sex, and race based barriers continued after 1920 as well.

Is preclearance still required?

Not generally. The Supreme Court struck down the Section 4(b) coverage formula in Shelby County v. Holder in 2013, so no jurisdiction is currently covered by Section 5 under that formula. A court can still order preclearance for a specific jurisdiction under Section 3(c) after finding a violation, but that is a court ordered remedy, not a general requirement.

Does the Act apply only to the South?

No. Section 2 applies nationwide, and Section 203 applies wherever a jurisdiction meets the coverage test, including outside the South. The original Section 5 formula did include many Southern states and counties, because it measured tests and low registration or turnout in 1964, but it also covered places outside the South.

What is the difference between Section 2 and Section 5?

Section 2 is a permanent, nationwide ban enforced through lawsuits, where a challenger must prove a violation in court. Section 5 was a temporary, preventive rule for covered jurisdictions only: a covered place had to get federal approval before a voting change took effect. Section 5 no longer operates generally because its coverage formula was struck down.

What changed in 1975 and 1982?

In 1975, Congress added language minority groups to the Act’s protection and required bilingual election materials in covered places under Section 203, and it extended Section 5 for seven years. In 1982, Congress extended Section 5 for 25 years and amended Section 2 so that a violation could be proved by a discriminatory result under the totality of circumstances, without proof of discriminatory intent.

What did Shelby County v. Holder decide, and what did it not decide?

It decided, by 5 votes to 4, that the Section 4(b) coverage formula was unconstitutional because it relied on outdated data. It did not strike down Section 5 itself or Section 2, and it did not hold that racial discrimination in voting was lawful. Its practical effect was to end general preclearance until Congress enacts a new formula.

What did Louisiana v. Callais change in 2026?

It held that Section 2 did not require Louisiana to create a second majority Black district, so that district was an unconstitutional racial gerrymander. It also reworked the Gingles framework, requiring stricter showings on illustrative maps, bloc voting, and present day intentional discrimination. It did not repeal Section 2, but it made redistricting claims substantially harder to win.

Where can a reader check a current voting rule?

Check the election official for the relevant state or county, and the Department of Justice Civil Rights Division. This article describes the Act and its history, not current deadlines, identification rules, polling places, or district maps, which vary by place and change over time.
