Thirteenth, Fourteenth & Fifteenth Amendments

Learning goals

Before this unit

Locate the period and region using the supplied background and timeline. Define unfamiliar terms and distinguish a document’s assertion from an established outcome.

Use three flexible 40–45-minute sessions: background and Parts 1–2 with checks; Parts 3–4 and the worked evidence case; then remaining practice, a timeline or labeled model, revision, and the exit check. Complete one short part at a time. Embedded checks count toward the practice set, rather than duplicate homework. Workshop, review, quiz, exams, and flexible support have separate time.

The Thirteenth Amendment, ratified in December 1865, abolished slavery and involuntary servitude except as punishment for a crime. The Fourteenth, ratified in July 1868, made everyone born in the United States a citizen and barred any state from denying due process or the equal protection of the laws.

The Fifteenth, ratified in February 1870, provided that the right to vote shall not be denied on account of race, colour or previous condition of servitude. Note what it does not say: it does not grant the vote, it forbids one particular reason for refusing it.

That drafting choice decided the next ninety years. A state that wanted to keep Black men from the polls could not say so, but it could require a literacy test, a poll tax or a property qualification and apply them as it pleased.

Build your understanding

Use three flexible 40-45-minute sessions: the three texts and what each closes; how the Fifteenth was worked around; reading the registration figures, then the practice set, revision and the exit check. Workshop, review, quiz and exams have separate time.

Part 1 · Three amendments, each closing the last one's gap

The Thirteenth ended the institution. It was necessary because the Emancipation Proclamation was a war measure that had never reached the loyal slave states and might not survive the peace. Its exception for punishment after conviction of a crime was barely debated and became, within five years, the legal foundation of convict leasing, in which states rented prisoners to private companies under conditions that killed a great many of them.

The Fourteenth answered the Black Codes. Section 1 is the one that matters most: everyone born here is a citizen of the United States and of the state they live in, and no state may abridge the privileges or immunities of citizens, deprive any person of life, liberty or property without due process, or deny any person the equal protection of the laws. It says person rather than citizen in the second half, which is why it reaches non-citizens too.

It also contained a punishment nobody ever used. Section 2 provides that a state denying the vote to adult male citizens shall have its representation in Congress cut in proportion. Southern states denied the vote wholesale for seventy years and no Congress ever reduced a single seat.

The Fifteenth answered the fact that the Fourteenth had not actually required Black suffrage. Republicans had reasons both principled and practical: Black votes were the basis of their southern support. The amendment passed in a form narrow enough to pass, which is to say narrow enough to be evaded.

Pause and explain

Why was the Fourteenth Amendment needed when the Civil Rights Act of 1866 said much the same thing?

Check your reasoning after answering

Because a statute can be repealed by the next Congress and struck down by a court, and this one had passed only over a presidential veto. Putting citizenship, due process and equal protection into the Constitution made them proof against an ordinary legislative majority. The same reasoning had produced the Thirteenth Amendment rather than relying on the Proclamation.

Part 2 · How a state kept the vote without mentioning race

Mississippi went first, with a new constitution in 1890, and the others copied it over the following fifteen years. The devices were a poll tax payable months before the election and in cash, a literacy test in which an official decided whether an applicant could read and interpret a clause of the state constitution, and a property or residency requirement.

None of them names race, and all of them were administered by a white registrar with complete discretion. A Black schoolteacher could be failed on an interpretation question; a white man who could not read could be passed. Where even that was thought insufficient, a grandfather clause exempted anyone whose grandfather had been entitled to vote before 1867, which no Black applicant's had been.

The Supreme Court let it stand. In Williams v. Mississippi in 1898 it held that the state's provisions did not on their face discriminate by race, and that proving discriminatory administration was the challenger's burden. The grandfather clause was finally struck down in 1915, by which time the registration rolls had already been cleared and the other devices remained.

This is the single most transferable idea in the unit. A rule can be written in perfectly neutral words, applied by officials with discretion, and produce an almost perfectly racial result -- and then be defended on the ground that the words are neutral. Learning to ask what a rule does rather than only what it says is most of what historical and civic literacy consists of.

Louisiana's own registration returns. The 1898 constitution never used the word race; it used a literacy test, a poll tax, a property qualification and a grandfather clause, and Black registration fell by roughly 99 per cent in eight years.

Pause and explain

How could a literacy test be racially discriminatory if it applied to everyone?

Check your reasoning after answering

Because a registrar decided who passed. The test asked an applicant to read and interpret a clause of the state constitution, and the official judging the interpretation had complete discretion, so educated Black applicants failed and illiterate white ones passed. A grandfather clause exempting men whose grandfathers voted before 1867 excused white applicants from taking it at all.

Part 3 · Reading the collapse

The figures in the diagram are the state of Louisiana's own. In 1896, 130,344 Black men were registered. In 1900, two years after the new constitution, 5,320. In 1904, 1,342. The Black share of the electorate fell from about 44 per cent to under one per cent while the Black share of the adult male population barely moved.

A fall like that cannot be explained by people losing interest. The population was there, the registration requirement had changed, and the figures move in the year the requirement changed. Historians look for exactly this shape: a sharp break timed to a known cause, with the underlying population flat.

Compare that with the change the same figures would show for white registration, which fell too -- the poll tax caught poor white men as well -- but by a fraction as much, and many of those were restored by the grandfather clause. The two curves together are the argument: a rule that was neutral on its face fell on one group roughly a hundred times harder.

What followed lasted until the Voting Rights Act of 1965, which worked by attacking the administration rather than the wording, requiring states with this history to get federal approval before changing voting rules at all. That is nearly a century between the Fifteenth Amendment and the law that made it operate, which is the measure of how much a well-drafted evasion can be worth.

Pause and explain

What makes the registration figures strong evidence rather than just a striking statistic?

Check your reasoning after answering

The timing and the flat baseline. The fall begins in the years the new constitution took effect rather than drifting gradually, and the Black adult male population did not change over the same period, so the drop cannot be population loss. Comparing it with the much smaller fall in white registration under the same rules isolates the effect of how the rules were applied.

Part 4 · What the amendments did do

It would be a mistake to finish this unit concluding that the amendments were worthless. They abolished slavery outright and permanently, which is not a small thing, and they wrote birthright citizenship into the Constitution, which remains the law and remains contested.

The Fourteenth Amendment in particular became the main instrument of American constitutional law in the twentieth century, long after Reconstruction ended. Equal protection is the clause behind Brown v. Board of Education in 1954; due process is the clause through which most of the Bill of Rights was applied against the states at all.

So the accurate summary is that the amendments were written to be enforced and were then not enforced for roughly ninety years, and that when enforcement finally came it came using their text, unchanged. The words were adequate; the political will was not, and the gap between the two is where the period's history actually lives.

That also means the century after 1870 is not a story of a law failing but of a country declining to use one. It is a distinction worth holding on to, because the two produce completely different conclusions about what to do next.

One last caution about the sources. The registration figures in this lesson come from the states that were doing the excluding, which is unusual and useful: an institution reporting a number that damns it is about as reliable as evidence gets, because it had every reason to report otherwise. When you meet a statistic in a textbook, the question to ask first is not whether it is large but who counted it and what they stood to gain by the count coming out differently.

Pause and explain

Why is it wrong to say the Reconstruction amendments failed?

Check your reasoning after answering

Because the text held and the enforcement did not. The Thirteenth permanently abolished slavery and the Fourteenth's citizenship, due process and equal protection clauses are still the basis of American constitutional law, including Brown v. Board of Education. What lapsed for ninety years was the willingness to enforce them, and when enforcement returned it used the same unaltered words.

Apply the whole unit · Read a registration roll

In a parish, Black men make up 50% of the adult male population. In 1896, 9,000 of the 20,000 registered voters are Black. After a new state constitution, the 1904 roll shows 11,200 registered voters, of whom 150 are Black. The adult male population has not changed.

Your task

Compute the change, and build the argument a historian would make from it.

What your response should show

  • Computes 45% and about 1.3% as the Black share of registration
  • Gives the fall in Black registration as roughly 98 per cent
  • Explains why an unchanged population rules out competing explanations
  • States the facially-neutral defence fairly and answers it with administration
Response guidance — after your attempt
  1. Give the Black share of registered voters in 1896 and in 1904.

  2. Work out the percentage fall in the number of Black men registered.

  3. Explain why the stable population figure is essential to the argument.

  4. Say what a defender of the new constitution would argue, and how you would answer.

In 1896, 9,000 of 20,000 is 45 per cent; in 1904, 150 of 11,200 is about 1.3 per cent. Set that against the population: Black men are 50% of the adult men in the parish, so by 1904 a group that is half the eligible population holds about one voter in seventy-five on the roll. The number of Black men registered fell from 9,000 to 150, a drop of about 98 per cent. The stable population figure is what rules out the ordinary explanations: nobody moved away and nobody died in the required numbers, so the change has to lie in who was allowed to register rather than in who was there. Notice too that white registration rose, which is the opposite of what a general tightening would produce. A defender would say the constitution applied the same literacy and tax requirements to every applicant and names no race, which is true of the text. The answer is that the test was graded by a registrar with full discretion and that a grandfather clause exempted men whose grandfathers had voted before 1867, so the rule's wording and the rule's operation were two different things -- and the figures measure the operation.

Read the records yourself

Parent / teacher teaching notes

Ask for one because-statement, a dated connection, and a source limitation. Give specific feedback and time to revise. Allow notes, a glossary, oral explanations, or a labeled timeline. Evaluate context, evidence, and reasoning rather than the learner’s politics, religion, cultural identity, or agreement with the model wording. Do not require family disclosure or role-play of slavery or persecution.

The key idea

Three amendments ended slavery, made citizenship a birthright and barred racial bars to voting. Each was written to close a loophole in the one before it, and each was then worked around by laws that never mentioned race at all.

Worked examples

Example 1 · Worked evidence case

Explain what the counts show and why the protection alone does not describe full participation.
  1. Separate eligibility, registration, and voting.
  2. Calculate recorded voting as half of eligible adults.
  3. Avoid inventing reasons and seek access and enforcement evidence.
Answer: Twenty of 40 eligible adults vote, or 50%; 25 register. The counts show distinct stages of access, not the reason every other person did not participate. A protection can change the legal framework while resources, rules, choices, or threats affect practice. Additional dated records would test those possibilities.

Example 2 · Compare a second claim after your attempt

A later official refuses to enforce a right. Does that automatically erase the constitutional provision?
  1. Identify the relevant period, institution, or evidence category.
  2. No. Nonenforcement and textual repeal are different. Describe the provision, the refusal, available institutions, and consequences with dated evidence rather than conflate them.
  3. State the narrower conclusion the supplied information can support.
Answer: No. Nonenforcement and textual repeal are different. Describe the provision, the refusal, available institutions, and consequences with dated evidence rather than conflate them.

Avoid these mistakes

Check your understanding

Why is “three amendments gave everyone the same rights” too vague?

Discuss the answer

It omits different subjects, dates, limits, eligibility, and enforcement. Identify each provision and compare its stated scope with practical access.

Does recognition of citizenship prove equal treatment in every institution?

Discuss the answer

No. Compare text with implementation, administration, enforcement, and affected people’s evidence. Legal recognition and practical treatment are connected but distinct.

Words to know

context
The time, place, institutions, and conditions surrounding an event.
primary source
Evidence created in the period or activity being investigated; its form does not automatically guarantee accuracy.
interpretation
An explanation of evidence that can be compared with context and other records.
equal protection
A constitutional protection concerning treatment under law; its historical interpretation and enforcement require study.
disenfranchisement
Loss or denial of political voting access through rules, administration, intimidation, or other barriers in a specified setting.

Extend the historical inquiry

If you use a linked record, identify creator, date, audience, purpose, form, and a specific claim it supports. Keep original wording separate from course paraphrase. Seek a different independently produced record that would test an inference.

In the real world

Trace a dated claim to its evidence and distinguish stated aims, institutions, and actual access. Describe people and communities without universal stereotypes.

Exit check

Why can rights text remain while practical protection declines?

Check your explanation after answering

Enforcement, officials’ actions, intimidation, resources, and institutional decisions affect access. A text’s continued existence does not independently establish effective protection.

Explain your reasoning without notes. If a key idea is missing, revisit the lesson and try again.

Problem 1

Why is “three amendments gave everyone the same rights” too vague?
Answer and explanation

It omits different subjects, dates, limits, eligibility, and enforcement. Identify each provision and compare its stated scope with practical access.

Problem 2

Does recognition of citizenship prove equal treatment in every institution?
Answer and explanation

No. Compare text with implementation, administration, enforcement, and affected people’s evidence. Legal recognition and practical treatment are connected but distinct.

Problem 3

Did the Fifteenth Amendment itself provide national women’s suffrage?
Answer and explanation

No. Its specified prohibited grounds did not include sex-based exclusion. Separate its protection from later changes and actual participation.

Problem 4

Why can rights text remain while practical protection declines?
Answer and explanation

Enforcement, officials’ actions, intimidation, resources, and institutional decisions affect access. A text’s continued existence does not independently establish effective protection.

Problem 5

Invented complete model: a newly protected category contains 40 eligible adults; 25 register and 20 vote safely in a recorded election. Reasons for the missing registrations are not supplied. Explain what the counts show and why the protection alone does not describe full participation.
Answer and explanation

Twenty of 40 eligible adults vote, or 50%; 25 register. The counts show distinct stages of access, not the reason every other person did not participate. A protection can change the legal framework while resources, rules, choices, or threats affect practice. Additional dated records would test those possibilities.
