White supremacy is the ideology that white people are superior to other races and should hold political, social, and economic power over them. In APUSH, it explains why Deep South states seceded after Lincoln's 1860 election and why racial inequality persisted into the civil rights era.
White supremacy is the belief that white people are racially superior and entitled to dominate other groups. On the AP exam, the word that matters is ideology. White supremacy isn't one law or one organization. It's the underlying belief system that produced slavery's defense, secession, segregation, and racial violence across multiple periods.
You'll see it most directly in Topic 5.7, where the secession declarations of Deep South states openly named the protection of slavery and white supremacy as their reason for leaving the Union after Lincoln won in 1860 without a single Southern electoral vote (KC-5.2.II.D). But the ideology outlives the Confederacy. It gets rebuilt into Jim Crow laws, enforced by groups like the Ku Klux Klan, and challenged head-on by the civil rights and Black Power movements in Period 8. That long arc, an idea surviving even when its institutions get destroyed, is exactly the kind of continuity APUSH loves to test.
This term sits in two places in the CED, and that gap is the point. In Unit 5, it supports APUSH 5.7.A (describe the effects of Lincoln's election). The secession crisis only makes sense if you understand that Southern leaders saw a free-soil Republican president as a threat to a social order built on white supremacy. In Unit 8, it supports APUSH 8.15.A (explain the extent to which events from 1945 to 1980 reshaped national identity). The civil rights movement, Black nationalism, and the Black Power Movement were all responses to white supremacy's persistence a century after the Civil War. For the American and National Identity (NAT) and Social Structures (SOC) themes, white supremacy is one of the strongest continuity threads you can argue across Periods 5 through 8.

Election of 1860 and Secession (Unit 5)
When Lincoln won on a free-soil platform with zero Southern electoral votes, Deep South states seceded. Their declarations explicitly said they were protecting slavery and white supremacy. This is the clearest primary-source evidence on the exam that secession was about race and slavery, not abstract states' rights.
Jim Crow Laws (Units 6-7)
After Reconstruction ended, white supremacy didn't disappear with slavery. It got written into state law as segregation, poll taxes, and literacy tests. Think of Jim Crow as white supremacy translated into a legal code.
Ku Klux Klan (Units 5 and 7)
The Klan is white supremacy enforced through violence. It appears twice in APUSH, first terrorizing freedpeople during Reconstruction, then reviving in the 1920s with a wider target list. Two appearances, one ideology.
Black Power Movement (Unit 8)
By the mid-1960s, activists frustrated with the slow pace of integration argued that white supremacy was baked into American institutions, not just Southern laws. Black Power and Black nationalism pushed for self-determination as a direct answer to that deeper problem, which is exactly what Topic 8.15 asks you to weigh when judging how much national identity actually changed.
Multiple-choice questions use white supremacy as cause-and-effect evidence. A classic stem gives you a secession declaration citing slavery and white supremacy and asks which effect of Lincoln's election it shows (answer: Southern states seceding to protect the slave system). Period 8 questions flip it forward, asking why the Black Power Movement emerged from the limits of earlier civil rights approaches. No released FRQ has used the term verbatim, but it's exactly the kind of through-line a continuity-and-change LEQ or a Period 5 or Period 8 DBQ rewards. The move that earns points is being specific. Don't just write "racism existed." Name the form it took in that period, like secession declarations in 1860 or segregated institutions in 1960, and explain what changed and what stayed the same.
White supremacy is the ideology; Jim Crow is one of its legal expressions. White supremacy existed before, during, and after Jim Crow (it justified slavery in 1860 and resistance to civil rights in 1960). Jim Crow refers specifically to the segregation laws passed mostly between the 1880s and 1960s. On an essay, treating them as interchangeable costs you precision. Use white supremacy for the continuous belief system and Jim Crow for the specific legal regime.
White supremacy is the ideology that white people are superior and should hold power; it's the belief system, not any single law or group.
Deep South secession declarations in 1860-1861 explicitly cited protecting slavery and white supremacy, which is direct evidence that Lincoln's free-soil victory triggered secession (APUSH 5.7.A, KC-5.2.II.D).
After emancipation, white supremacy persisted in new forms, including Jim Crow segregation laws and Klan violence, making it a powerful continuity argument across Periods 5 through 8.
The Black Power Movement emerged in the mid-1960s partly because earlier civil rights approaches hadn't dismantled white supremacy embedded in institutions, a key piece of evaluating change in Topic 8.15.
On essays, name the specific form white supremacy took in each period instead of writing 'racism existed,' because precision is what earns evidence points.
It's the ideology that white people are racially superior and should dominate political, social, and economic life. APUSH tests it as the belief system behind slavery's defense, the 1860-1861 secession crisis, Jim Crow segregation, and the resistance the civil rights movement fought against.
No. The secession declarations of Deep South states explicitly named the protection of slavery and white supremacy as their reasons for leaving the Union after Lincoln's 1860 election. The 'states' rights' framing came later; the exam expects you to use the actual 1860-1861 evidence.
White supremacy is the ideology; Jim Crow laws were the specific segregation statutes (roughly 1880s-1960s) that put that ideology into legal code. The ideology predates and outlasts the laws, which is why it works as a continuity argument across multiple periods.
No. The Civil War ended slavery, but white supremacy survived in new forms, including Black Codes, Klan violence during Reconstruction, and Jim Crow segregation. That persistence is why the civil rights and Black Power movements of Period 8 were still confronting it a century later.
By the mid-1960s, activists argued that legal victories like ending formal segregation hadn't touched white supremacy embedded in economic and social institutions, especially outside the South. Black Power pushed for self-determination as a response to that deeper, structural problem.
