What this topic is asking
SSUSH9 also asks you to analyze how the war's purpose changed, from simply preserving the Union to ending slavery. You need the Emancipation Proclamation and its real effect, the role of African American soldiers, the meaning of the Gettysburg Address, and the Thirteenth Amendment that finally abolished slavery. This is core Domain 2 content and a bridge into Reconstruction.
The war's shifting purpose
The Emancipation Proclamation
Even with this limited legal reach, the Proclamation was a turning point in meaning:
- It made ending slavery an official Union war goal, giving the cause moral force.
- It discouraged Britain and France, which opposed slavery, from recognizing or aiding the Confederacy.
- It encouraged enslaved people to flee to Union lines and cleared the way for African American enlistment.
African American soldiers
About 180,000 African American men served in the Union army and navy, including units such as the famous 54th Massachusetts. Their service strengthened the Union war effort and made a powerful argument for full citizenship and rights after the war. SSUSH9 expects you to recognize this contribution.
The Gettysburg Address and the Thirteenth Amendment
Lincoln gave the war its larger meaning in the Gettysburg Address (1863), a short speech honoring the dead and calling for "a new birth of freedom" and government "of the people, by the people, for the people."
The Thirteenth Amendment is the first of the three Reconstruction Amendments (Thirteenth, Fourteenth, Fifteenth) and the legal end of American slavery.
Try this
Q1. Explain how the Emancipation Proclamation changed the purpose of the Civil War. [2]

Q2. Explain why the Thirteenth Amendment was necessary after the Emancipation Proclamation. [2]
- Cue. The Proclamation was a wartime order that applied only to areas in rebellion, so a constitutional amendment was needed to abolish slavery everywhere and permanently.

A single-select item (Domain 2, SSUSH9).
Correct answer: made ending slavery an official goal of the war, in addition to preserving the Union.
By declaring enslaved people in the rebelling states free, the Proclamation gave the war a moral purpose and discouraged Britain and France from aiding the South. Markers reward identifying the shift in the war's purpose to include ending slavery. Distractors claiming it immediately freed every enslaved person everywhere overstate its reach, since it applied to areas in rebellion.
