The Ku Klux Klan (KKK) is a white supremacist organization that used violence and intimidation to suppress African American rights during Reconstruction (Unit 5), then revived in the 1920s (Unit 7) as a nationwide nativist movement targeting Black Americans, immigrants, Catholics, and Jews.
The Ku Klux Klan was founded in the South right after the Civil War, and its first job was terror. Klansmen attacked Black voters, officeholders, and landowners to undo the gains of Reconstruction. This is the violence the CED points to in KC-5.3.II.E, where segregation, violence, court decisions, and local political tactics 'progressively stripped away African American rights.' The Klan was the violence part of that list. When a freedman tried to vote, run for office, or buy land, the Klan was often the force that stopped him.
The Klan then came back in the 1920s as a second, much bigger version. The new Klan was national, not just Southern, and it widened its target list to immigrants, Catholics, and Jews, riding the same nativist wave that produced the immigration quota laws after World War I. So when you see 'KKK' on the exam, your first move is to check the date. The Reconstruction Klan is a Unit 5 story about destroying Black political power in the South. The 1920s Klan is a Unit 7 story about nativism and the cultural battles between modern, urban America and traditional, rural America.
The Klan is one of the best continuity-and-change terms in APUSH because it shows up in two different units doing two related but distinct things. In Unit 5 (Topic 5.11), it supports APUSH 5.11.A, explaining how Reconstruction produced both change (the 14th and 15th Amendments) and continuity (white supremacist violence that kept the old racial order in place). In Unit 7 (Topics 7.7 and 7.8), it supports APUSH 7.8.A and 7.8.B, where the revived Klan is evidence of nativist backlash against immigration and of the 1920s controversies over race, religion, and modernism. If a DBQ or LEQ asks you to argue about the limits of Reconstruction, or about cultural conflict in the 1920s, the Klan is usable evidence in both. Few terms stretch across periods that cleanly.

Failure of Reconstruction (Unit 5)
The Klan is a big part of why Reconstruction failed on the ground. The 14th and 15th Amendments changed the law, but Klan violence against Black voters and officeholders meant the law often couldn't be enforced in the South. That gap between legal rights and lived reality is exactly what APUSH 5.11.A asks you to explain.
Nativism (Unit 7)
The 1920s Klan is nativism with a hood on. The same post-WWI fear of immigrants that produced the quota laws restricting southern and eastern European immigration also fueled Klan membership, which is why the second Klan attacked Catholics and Jews, not just Black Americans.
White Supremacy (Units 5 and 7)
White supremacy is the ideology; the Klan is the organization that enforced it with violence. Practice questions about the assault on Abram Colby, a Black Georgia legislator beaten by Klansmen, show this in action. Suppressing Black political activity was the point, not a side effect.
1920s Mass Media and National Culture (Unit 7)
Topic 7.7's new mass media, especially cinema, helped spread a national culture, and the second Klan rode that wave to grow far beyond the South. A regional terror group from the 1860s became a nationwide mass-membership movement partly because 1920s America had the communication tools to make it one.
Multiple-choice questions usually pair the Klan with a primary source, often testimony from a victim like Abram Colby, and ask what it reveals about how white supremacists maintained dominance or suppressed Black political activity during Reconstruction. The expected answer almost always centers on violence and intimidation as tools to destroy Black voting power. The 2017 SAQ used political cartoons from the Reconstruction era, and Klan violence is classic evidence for explaining what such images depict. For essays, the Klan works two ways. In a Unit 5 LEQ or DBQ on Reconstruction's failure, it's your evidence that legal change didn't equal real change. In a Unit 7 essay on 1920s cultural conflict, the revived Klan is evidence of nativist and traditionalist backlash. Just keep your eras straight, because mixing the two Klans is an easy way to lose evidence points.
Same name, different exam contexts. The first Klan (1860s-70s) was a Southern terror group focused on destroying Black political power during Reconstruction. The second Klan (1920s) was a national mass movement that added immigrants, Catholics, and Jews to its targets, fueled by postwar nativism. If your essay is about Reconstruction, use the first; if it's about 1920s cultural controversies, use the second. Citing the wrong one dates your evidence to the wrong period.
The original Ku Klux Klan formed after the Civil War and used violence and intimidation to suppress African American voting and officeholding during Reconstruction.
Klan terror is core evidence for why Reconstruction failed in practice even though the 14th and 15th Amendments changed the law (KC-5.3.II.E).
The Klan revived in the 1920s as a national movement that targeted Black Americans, immigrants, Catholics, and Jews, reflecting the same nativism behind the postwar immigration quotas.
The 1920s Klan is evidence of the decade's cultural conflicts over race, religion, and immigration tested in Topic 7.8.
On the exam, always date the Klan reference first, because the Reconstruction Klan belongs to Unit 5 arguments and the 1920s Klan belongs to Unit 7 arguments.
Sources like Abram Colby's testimony show that Klan violence was specifically aimed at destroying Black political participation, not random lawlessness.
The KKK was a white supremacist organization founded in the post-Civil War South that used terror to suppress African American rights during Reconstruction, then revived in the 1920s as a national nativist movement. It appears in Topic 5.11 (Failure of Reconstruction) and Topics 7.7-7.8 (the 1920s).
No. The original Klan was a Southern terror organization aimed at destroying Black political power in the 1860s-70s. The second Klan of the 1920s was a separate revival that went national and broadened its targets to immigrants, Catholics, and Jews, driven by post-WWI nativism.
Postwar nativism. After World War I, fear of immigrants from southern and eastern Europe and anxiety over rapid cultural change (urbanization, modernism, shifting race relations) fueled a mass Klan revival. It grew from the same backlash that produced the immigration quota laws.
Klan violence kept African Americans from exercising the rights the 14th and 15th Amendments guaranteed on paper. Attacks on Black voters and officeholders, like the assault on Georgia legislator Abram Colby, helped white supremacists regain political control of the South.
White supremacy is the ideology; the Klan is an organized group that enforced it through violence and intimidation. On the exam, the Klan works as specific evidence for the broader pattern of white supremacist tactics in Topics 5.11 and 7.8.
