What did the Emancipation Proclamation achieve?

The Emancipation Proclamation achieved the significant result of claiming freedom for slaves in Confederate states. This executive order was announced by President Abraham Lincoln during the Civil War on January 1, 1863, and it declared that all enslaved people in states that were in rebellion against the Union were to be set free. Although it did not immediately free all enslaved individuals, it was a critical step towards the eventual abolition of slavery in the United States and set the stage for the passage of the Thirteenth Amendment. This proclamation not only aimed to weaken the Confederate states' labor force but also allowed for the enlistment of African American soldiers into the Union Army, further bolstering the fight against slavery and for civil rights.

The other options mentioned do not relate to the Emancipation Proclamation. For instance, while the establishment of public education is an important social issue, it was not a result of this proclamation. Voting rights for women and the conclusion of World War I are also unrelated topics, as the Emancipation Proclamation focused specifically on the issue of slavery during the U.S. Civil War.
