AP U.S. History: Unit 4.5
Student Edition
Slavery in Antebellum America
I. The Rise of "King Cotton"
A. Prior to 1793, the Southern economy was weak: depressed prices,
unmarketable products, soil-ravaged lands, and an economically
risky slave system.
Some leaders, such as Jefferson (who freed 10% of his slaves), believed slavery would gradually die out but it could not be done
immediately. "We have a wolf by the ears."
B. Eli Whitney’s Cotton Gin (1793)
1. Impact: Cotton production became profitable; 50x more effective
than picking cotton by hand.
a. Resulted in an explosion in slavery
b. Cotton came to surpass tobacco, rice, and indigo production.
2. A “Cotton Kingdom” developed into a huge agricultural factory.
a. Western expansion into lower gulf states: Louisiana,
Mississippi, Alabama
b. Slaves were brought into new regions to cultivate cotton.
3. A huge domestic slave trade emerged.
Importation of slaves from Africa was abolished in 1808
C. Trade
1. Cotton exported to England; revenues from sale of cotton used to
buy northern goods
Britain heavily dependent on U.S. cotton for its textile factories; 80% came from U.S.
2. Prosperity of both North and South rested on slave labor
3. Cotton accounted for 57% of all American exports by 1860.
The South produced 75% of the world’s cotton.
II. The Three Souths
A. Generalizations
1. The further North, the cooler the climate, the fewer the slaves,
and the lower the commitment to maintaining slavery..
2. The further South, the warmer the climate, the more the slaves,
and the higher the commitment to maintaining slavery.
3. Mountain whites along Appalachian Mountains would mostly
side with the Union during the Civil War.
Lived in western Virginia, eastern Tennessee, northeastern Kentucky, western South Carolina, northern Georgia and
Alabama.

1860
5. There was not a unified South except for a common trait of
resistance to the perceived outside interference of the federal gov’t.
B. Border South: Delaware, Maryland, Kentucky, & Missouri
1. Plantations were more scarce; cotton cultivation was almost
nonexistent; tobacco was the main crop (as in the Middle South);
and more grain production existed (as in the Middle South).
2. Unionists would overcome Disunionists during and after the Civil
War.
3. 1850, slaves = 17% of population.; avg. of 5 slaves per slaveholder

for 46% of the South’s free blacks
5. 22% of white families owned slaves.
6. Comprised 6% of all southerners who owned more than 20 slaves
in the South; comprised only 1% of the South’s ultra-wealthy
7. Produced over 50% of the South’s industrial products
C. Middle South: Virginia, North Carolina, Tennessee, Arkansas
1. Each state had one section resembling the Border South and
another resembling the Lower South.
Some industrial production: Tredegar Iron Works in Virginia used slave labor
2. Unionists prevailed after Lincoln was elected; Disunionists
prevailed after the war began.
3. Many plantations existed in eastern Virginia and western Tennessee
4. 1850, slaves = 30% of population; avg. of 8 slaves per slaveholder
5. 36% of white families owned slaves.
6. Comprised 32% of all who owned more than 20 slaves in South and
14% of the ultra-wealthy
D. Lower South: South Carolina, Florida, Georgia, Alabama,
Mississippi, Louisiana, Texas
1. Most slaves lived in the “cotton belt” or "black belt" of the
Deep South along river valleys.
2. Plantations were prevalent; cotton was king; accounted for 95% of
the South’s cotton and almost all sugar, rice, and indigo.
3. Disunionists (secessionists) would prevail after Lincoln was
elected.
4. 1850, slaves = 47% of population; avg. of 12 slaves per slaveholder
5. Less than 2% of blacks were free; only 15% of South’s free blacks

8. Produced less than 20% of South’s industrial products
III. The "Peculiar Institution"
A. The Planter "Aristocracy"
1. The South was ruled politically and economically by wealthy
plantation owners.
a. In 1850, only 1,733 families owned more than 100 slaves yet
they dominated southern politics.
b. The South was the least democratic region of the country.
A huge gap between rich and poor existed.
Poor public education (planters sent kids to private schools) 2. Planters carried on the "cavalier" tradition of early Virginia.
a. This was reflected in its military academies.
b. Its elite culture included chivalry among a landed genteel-class.
B. Plantation system
1. Required heavy investment of capital in slave labor
2. Risky: slaves might die of disease, injure themselves, or escape.
3. One-crop economy (e.g. cotton, tobacco)
a. Discouraged diversification of agriculture, especially
manufacturing
b. Southerners resented the North’s huge profits at their expense.
Complained of northern middlemen, bankers, agents, and shippers
Resented being so dependent on northern manufactures and markets
4. Repelled large-scale European immigration
a. Only 4.4% of foreign-born Americans were part of the South’s
population in 1860; 18.7% in the North.
b. Slave labor was far cheaper; fertile land was too expensive for
most immigrants; immigrants were not familiar with cotton
production.
c. The South was the nation’s most Anglo-Saxon (English) region.
C. Plantation slavery
1. Nearly 4 million slaves lived in the U.S. by 1860; quadrupled in
number since 1800.
a. Legal imports of slaves ended in 1808.
Thousands of slaves were smuggled into the South despite the death penalty for slave traders.

children
White slave owners often fathered a sizable mulatto
