Answer:Harriet Beecher Stowe popularized the anti-slavery movement with her novel Uncle Tom’s Cabin. Slavery was prominent in the South, many Americans did not encounter slavery daily; therefore, many did not fully grasp its appalling nature.Areas of the city had been wrecked in the Cincinnati riots of 1829, when ethnic Irish attacked blacks, trying to push competitors out of the city. Beecher met a number of African Americans who had suffered in those attacks, and their experience contributed to her later writing about slavery. Riots took place again in 1836 and 1841, driven also by native-born anti-abolitionists.[
