The Chronicles of Democracy | AP Government Pre-Teach

AP Exam Connection

Reconstruction is where the federal government first claims real power over who votes. The 14th and 15th Amendments — and Congress's power to enforce them — anchor a huge share of modern voting litigation. Master the difference between being a citizen and having a specific kind of voting discrimination prohibited.

Two sentences, two different promises

Read them side by side. (A) “All persons born in the United States… are citizens.” (B) “The right… to vote shall not be denied… on account of race, color, or previous condition of servitude.”

Predict first — One of these makes you a citizen; the other limits how a state may deny the vote. Which is which — and does either one, by itself, guarantee that a Black man in Mississippi could actually cast a counted ballot in 1875?

State the rule the 15th Amendment created — and note what it does NOT create.

Which case did the 14th Amendment overturn, and on what question?

Give the exception: what qualifications could a state still impose after 1870?

Which level of government acted in the Enforcement Acts, and why was that necessary?

What new word did the 14th Amendment add to the Constitution's voting language?

Explain · The Lesson

In Dred Scott (1857) the Supreme Court held that Black Americans descended from enslaved people could not be citizens. Reconstruction reversed this. The Civil Rights Act of 1866 declared people born in the United States citizens regardless of race, and the Fourteenth Amendment (1868) constitutionalized national and state citizenship, guaranteed Equal Protection and Due Process, and — in Section 2 — threatened to cut a state's congressional representation if it denied the vote to qualifying male citizens.

The Fifteenth Amendment (1870) then prohibited denying or abridging the vote on account of race, color, or previous condition of servitude, and the Naturalization Act of 1870 extended naturalization to people of African descent (Asian immigrants generally remained excluded). Because a right unenforced is a right in name only, the Enforcement Acts of 1870–1871 criminalized intimidation and violence and authorized federal intervention.

Prohibition, not a grant

The Fifteenth Amendment did not create an affirmative, unrestricted right of every citizen to vote. It prohibited one reason for denial — race. States kept authority over other qualifications, which is precisely the space Jim Crow would exploit with devices that never mentioned race out loud.

Date	Rule / Law	Government Actor	Population	Formal Change	Barrier Remaining
1848	Treaty of Guadalupe Hidalgo	Treaty (federal)	Mexican residents of ceded territory	Path to U.S. citizenship for many	Racial & linguistic discrimination in practice
1857	Dred Scott v. Sandford	Supreme Court	Black Americans	Held they could not be citizens	Overturned only by the 14th Amendment
1866	Civil Rights Act	Congress	People born in the U.S.	Declared citizenship irrespective of race	A civil-rights statute, not a suffrage act
1868	14th Amendment	Amendment	All persons born/naturalized here	Citizenship, Equal Protection, Due Process; §2 apportionment penalty	Introduces “male”; creates no general right to vote
1870	15th Amendment	Amendment	Black men (and all races)	No denial of vote for race/color/servitude	Other qualifications still allowed → Jim Crow openings
1870	Naturalization Act	Congress	African-descended immigrants	Naturalization extended beyond “white”	Asian immigrants still generally excluded
1870–71	Enforcement / KKK Acts	Congress	Black voters	Criminalized violence & intimidation; federal enforcement	Enforcement waned after Reconstruction

Compare two amendments

In two sentences, contrast what the 14th and 15th Amendments each did for voting. Your answer must make clear that one is chiefly about citizenship/equal protection and the other about a specific prohibited ground of denial.

Could this person vote? — apply before you quiz

A Black man in a former Confederate state in 1872, with federal marshals present, versus the same man in 1890 after federal enforcement collapsed. His formal right under the 15th Amendment is identical in both years. What changed?

What did the Fourteenth Amendment's Citizenship Clause establish?

AP SCOTUS-style reasoning

Central question: Distinguish “being a citizen” from “having racial discrimination in voting prohibited.” Explain why a person could possess the first without securing the second in practice, and identify which constitutional provision does which work.
