About this source
What it is
This engraving by cartoonist Thomas Nast was published in Harper's Weekly in 1867. It shows President Andrew Johnson dressed as a Roman emperor, watching from a gallery as a violent massacre unfolds below, an allegory for the 1866 New Orleans riot in which Black citizens were killed.
Why it matters
Thomas Nast was one of the most influential political cartoonists of his time, and this piece sharply criticized Johnson for policies that critics blamed for enabling racial violence in the Reconstruction South. It reflects how deeply divided public opinion was over Johnson's handling of Reconstruction and Black citizens' safety and rights.
Look closer
- Why would Nast portray Johnson as a Roman emperor rather than as himself?
- What is the cartoonist suggesting by showing Johnson merely watching the violence rather than acting?
- How does satire like this differ from a straightforward news report of the same event?
