Written by Harriet Beecher Stow and published in 1852. Uncle Tom’s Cabin portrayed the evils of the institution of slavery. The novel sold 1.2 million copies in two years and reached millions more through dramatic adaptations.

Unrestricted submarine warfare

The German U-boat policy in which submarines attacked any ship—military, merchant, or civilian—without warning. After a period in which Germany practiced limited submarine warfare as promised by the Sussex Pledge, the resumption of unrestricted submarine warfare in January 1917 pushed the U.S. even closer to entering World War I.

Utopian communities

Small, experimental communities that sprang up in the U.S. beginning in the late 1820s. In these communities, reformers attempted to build perfect societies and present models for other communities to emulate. Most of these communities collapsed by the late 1840s.
