At the Friends (Quaker) Meeting House at the corner of Federal and Pearl Streets, abolitionist William Lloyd Garrison began the Maine anti-slavery movement with a speech in 1832, advocating immediate emancipation without compensation to slave owners instead of colonizing free African Americans to Liberia. In 1836, Portland's first anti-slavery riot took place there during an anti-slavery speech by Henry Brewster Stanton. The meeting house was attacked again in 1847 when Garrison, Frederick Douglass, and Charles Lenox Remond attempted to lecture, and anti-slavery women successfully protected the speakers.
