Plessy and judicial ratification of Jim Crow
Plessy v. Ferguson gave constitutional cover to segregation and helped entrench Jim Crow.
Claim
Court-approved segregation made racial exclusion more durable by giving state discrimination federal legitimacy.
What Happened
The Supreme Court upheld Louisiana's separate-car law and accepted separate-but-equal doctrine.
Why It Matters
The decision helped lock civic inequality into schools, transport, voting, housing, and public life.
Model Read
Scores are structured judgments. The range widens when confidence falls.
Weighted toward human damage, realized harm, and durability.
Long-term damage discounted for source and causal uncertainty.
High confidence. Better evidence should narrow this band.
Strongest Counterargument
Plessy did not create every Jim Crow law; state and local systems were already building segregation.
Incentive Check
Who benefits from exaggerating this?
Those who treat one opinion as the whole Jim Crow system may understate local and state responsibility.
Who benefits from minimizing this?
Those who treat the case as old doctrine may miss how long judicial approval shaped real life.
