Question

1. what key political decision made by abraham lincoln helped change the nature of the war in the unions favor?○ running for reelection○ allowing southern states to secede○ passing the thirteenth amendment○ issuing the emancipation proclamation

Explanation:

The Emancipation Proclamation, issued by Lincoln in 1863, redefined the Civil War from a conflict to preserve the Union to also a fight to end slavery. This shifted international perception (discouraging European support for the Confederacy) and allowed enslaved people to join Union forces, strengthening the Union's military and altering the war's trajectory. Lincoln did not allow secession, the 13th Amendment passed after the war's end, and his re-election was a result of war momentum, not the decision that changed the war's nature.

Answer:

D. issuing the Emancipation Proclamation
