The Emancipation Proclamation declared that enslaved people in Confederate - held territory were free (eliminating lawful slavery in certain areas), it helped change the meaning of the war to include the fight against slavery, and it led to the recruitment of Black soldiers. However, it did not address the voting rights of Black property holders. Voting rights for Black men (even property - holding ones) came later with the 15th Amendment.
