Arguing Against Slavery

What arguments did abolitionists make against slavery? How did abolitionists propose to end slavery? These historical questions are at the center of this two-lesson unit focused on seven primary documents. In engaging with these questions and these documents, students will consider the impacts and the limits of abolition, a social movement that spanned hundreds of years.

How Did the Constitutional Convention Deal with Slavery?

This short video explains the differing perspectives that emerged about the Constitution and slavery. Some, like Frederick Douglass, believed that the Founders put slavery on the road to extinction while others, like Roger Taney, believed that the Constitution was a slaveholders’ document. Professor Gordon Lloyd contends that the slavery clauses in the Constitution both limited and expanded slavery’s impact, and that the Founders alone do not bear responsibility for slavery’s later expansion.

Dolley Madison and Slavery

This short video presents Dolley Madison as a typical member of the antebellum slaveholding gentry. Dolley, like her southern contemporaries, saw slaves as property. Professor Catherine Allgor notes that when Dolley Madison began selling her slaves in the 1840’s, she was strongly criticized by the abolitionist press.

George Washington and Slavery

This short video analyzes Washington’s experiences as a “queasy slaveowner.” Having inherited and traded slaves as a younger man, Washington in later life gradually moved from being doubtful about the morality of the institution to being certain that the institution was “against the law of nature.” Professor W. B. Allen contends that Washington’s decision to free his slaves upon his wife’s death ensured that Mount Vernon’s enslaved families would remain intact and would be provided for.

“What to the Slave Is the Fourth of July?”

Frederick Douglass earned wide renown as an outspoken and eloquent critic of the institution of slavery. In this speech before a sizeable audience of New York abolitionists, Douglass reminds them that the Fourth of July, though a day of celebration for white Americans, was still a day of mourning for slaves and former slaves like himself, because they were reminded of the unfulfilled promise of equal liberty for all in the Declaration of Independence.

Slavery a Positive Good, John C. Calhoun

John C. Calhoun was a U.S. statesman and spokesman for the slave-plantation system of the South. He explains in this article that slavery gives people more serious opportunities to better themselves because of slaves. This source allows students to examine the supposed justifications for slavery and challenge the assumptions made by slaveowners.

Slavery: No Freedom, No Rights (Lesson Plan)

Examine the history of slavery in the United States. Trace the development and expansion of slavery in the 19th century and learn about the conflicts and compromises that occurred prior to the Civil War and the abolition of slavery.

From the basics about slavery to the attitudes that defended it and the efforts of those who wanted to see it abolished, in this lesson students learn about this dark part of America’s past.

** Please note: The section about the Missouri Compromise and the Compromise of 1850 has been moved to a new mini-lesson called Slave States, Free States that explores the debate about the expansion of slavery. We recommend teaching this mini-lesson along with the Slavery lesson. Find it in our Geography Library.

Gradual Emancipation of Slaves After 1780

This short video examines the gradual but limited emancipation that occurred before the Constitutional Convention. In Northern states, fewer slaves and less racist sentiment enabled states such as Pennsylvania to pass gradual emancipation laws while even some Southern states, where racism was more entrenched, made it easier for slaves to be freed. However, as Professor John Kaminiski notes, the great political leaders of the South took no bold actions to free their slaves.

Slavery and the Three-Fifths Compromise

This short video explains the role played by slavery in counting population for taxation and representation. Drawing upon an unsuccessful 1783 amendment to the Articles, James Madison suggested that the slave population be counted at 60% for both representation and taxation. Professor John Kaminski explains how this “federal ratio” reconciled Southerners (who wanted slaves counted as people for representation) and Northerners (who wanted slaves counted as property in determining taxation.)

Emancipation of Slaves Under the Constitution

This short video illustrates the approaches taken by the various states towards freeing their slaves. Pennsylvania and New York were among the first to provide a path to gradual emancipation, due in large part to the influence of Quakers and Methodists. Professor John Kaminiski discusses the various criteria for manumission: the age of the individual; what percentage of the individual’s racial background was African-American; and how well prepared the individual was for life as a freeman.
