What this topic is asking
Topic 3.5 covers the legal machinery of the Jim Crow South: how states stripped Black men of the vote and imposed legal segregation. The College Board wants you to know the specific devices of disfranchisement, the meaning of Jim Crow, and the role of Plessy v. Ferguson in giving segregation constitutional cover.
Disfranchisement
Jim Crow and Plessy v. Ferguson
The name "Jim Crow" came from a derogatory minstrel character and became shorthand for the whole regime of legalized segregation and subordination.
Evading the amendments
The deepest analytical point is the design. Disfranchisement and segregation were not accidents; they were engineered to work around the Reconstruction Amendments.
Poll taxes, literacy tests, and grandfather clauses evaded the Fifteenth Amendment by never mentioning race. "Separate but equal" evaded the Fourteenth Amendment's equal protection by pretending segregation treated the races equally. The result was a system that honored the letter of the amendments while destroying their purpose.
