Final answer:
The correct newspaper headline reflecting an event from the Reconstruction Period is "Former Slaves Made Citizens," which refers to the passing of the 14th Amendment granting citizenship to former slaves.
Step-by-step explanation:
The newspaper headline that would have appeared during the Reconstruction Period after the Civil War is "Former Slaves Made Citizens."
The Reconstruction Era was the period following the Civil War from 1865 to 1877, during which the United States began to rebuild and reintegrate the Southern states into the Union. A headline about the end of Jim Crow laws would not be accurate for this time because these laws were established after the Reconstruction Era and lasted until the mid-20th century. The Supreme Court issuing the Dred Scott Decision took place in 1857, prior to the Civil War and the Reconstruction, and therefore would not be a headline from that period.
Similarly, the Emancipation Proclamation was issued during the Civil War in 1863, not the Reconstruction. The 14th Amendment, granting citizenship to "all persons born or naturalized in the United States," including former slaves, was passed during Reconstruction in 1868, making the correct headline reflecting this significant change in American society.
