The Dred Scott case began in 1846 when slaves Dred and Harriet Scott sued for their freedom, basing their argument on the fact that they had lived in non-slave territories for a number of years. The case ended with the landmark U.S. Supreme Court decision of 1857 that not only denied Scott both citizenship and the right to sue in federal court, but ruled that he never had been free and that Congress did not have the right to prohibit slavery in the territories. The decision sparked increased sectional tensions in the years leading to the Civil War. Facsimiles and transcriptions of 85 legal documents relating to the Dred Scott case are provided on this website. The site also provides a chronology and links to 301 Freedom Suits—legal petitions for freedom filed by or on behalf of slaves—in St. Louis courts from 1814 to 1860.

Focusing on the experiences of Africans and African Americans in New York City, this collection presents nine galleries that explore various themes and time periods in the history of slavery. These include the Atlantic slave trade; slavery in Dutch New York; the growth of slavery in British Colonial New York; freedom for blacks during the Revolutionary War; the Gradual Emancipation Act of 1799; free blacks in public life; Emancipation Day (July 4, 1827), and the history of scholarship on slavery in New York City. Each gallery has three panels: a gallery overview, a main thematic presentation, and one focusing on people, places, and documents. Of special interest are two interactive maps with timelines in the Dutch New York gallery and the Revolutionary War gallery; a picture gallery on the portrayal of blacks in New York City's public life; and profiles of nine African Americans who lived in New York City during the early republic.

These more than 200 documents explore cultural connections between the experiences of African Americans and Irish immigrants in America. Materials relate to individual leaders, historical events, economic, political, and social factors, and cultural achievements. A section entitled "Making Connections" offers 15 questions about historical events and people that represent the intertwined histories of Africans and Irish in America.

Other topics include the end of English participation in the slave trade, the emergence of the nativist Know-Nothing Party in the 1850s, and Ku Klux Klan activities against Catholics and blacks after the Civil War. A section on "Acceptance" explores perceptions of individual and group identities and four timelines focus on displacement, oppression, discrimination, and acceptance in America. "Voices" provides a sample of 13 public statements and interviews on ethnicity and race from ordinary modern Americans. The site also provides a bibliography; an essay by writer James McGowan, a black American with an Irish paternal grandfather; and links to related websites.

James Allen has assembled a collection of chilling photographs of lynchings throughout America, primarily from the late 19th and early 20th centuries. Many were circulated as souvenir postcards. The site is a companion to Allen's book Without Sanctuary. The exhibit can be experienced through a flash movie with narrative comments by Allen or as a gallery of more than 80 photographs with brief captions. Most images also have links to more extensive descriptions of the circumstances behind each specific act of violence.

While the vast majority of lynching victims were African Americans, white victims are also depicted. Individually and as a group, these images are disturbing and difficult to fathom. They provide, however, an excellent resource for approaching the virulence and impact of racism in late 19th and 20th-century America.

This collection of more than 1,230 images depicts the enslavement of Africans, the Atlantic Slave Trade, and slave life in the New World. Images are arranged in 18 categories, including pre-Colonial Africa, capture of slaves, maps, slave ships, plantation scenes, physical punishment, music, free people of color, family life, religion, marketing, and emancipation.

Many of the images are from 17th- and 18th-century books and travel accounts, but some are taken from sketches within slave narratives, Harper's Weekly, and Monthly Magazine. Reference information and brief comments, often an excerpt from original captions, accompany each image. Although there is no interpretation or discussion of historical relevance, these images are valuable for learning about representations of slavery in American slave societies, especially in the Caribbean and Latin America.
