3. Authorities & decisions: Abolition and the Civil War amendments

Decision-makers, laws and consequences

Abraham Lincoln issued the Emancipation Proclamation effective January 1, 1863, applying to designated areas in rebellion. Congress proposed the Thirteenth Amendment in 1865, the Fourteenth in 1866 and the Fifteenth in 1869; ratification followed in 1865, 1868 and 1870.

Federal enforcement was contested and later weakened by segregation, disenfranchisement and racial violence. Constitutional language alone did not guarantee effective equal citizenship.

Institutional consequences

The authorities identified above acted within institutions that determined who could govern, enforce decisions and challenge official power. The resulting changes to political participation, legal status, military control or property administration are part of the historical record of this specific event, rather than evidence that every later government followed the same path.
