Unveiled
The passage and enforcement of the 1850 Fugitive Slave Law meant that no escaped slave was safe, since even those living in the free North could be arrested and re-enslaved. After passage of the Law, escaped slave women living in the North sometimes wore veils when they appeared in public to avoid identification by slave-catchers.
