Prior to the Civil War, Brooklyn Heights was a locus of the Abolitionist movement, due to the speeches and activities of Henry Ward Beecher, the pastor of Plymouth Church, now the Plymouth Church of the Pilgrims. Beecher was a nationally known figure famous on the lecture circuit for his novel oratorical style, in which he employed humor, dialect, and slang. Under Beecher, so many slaves passed through Plymouth Church on their way to freedom in Canada that later generations have referred to the church as the "Grand Central Station of the Underground Railroad". To dramatize the plight of those held in captivity, Beecher once brought a female slave to the church and held an auction, with the highest bidder purchasing not the slave, but her freedom. Beecher also raised money to buy other slaves out of captivity, and shipped rifles to abolitionists in Kansas and Nebraska in crates labelled "Bibles", which gave the rifles the nickname "Beecher's Bibles".
