Slavery in the United States is a deeply significant part of American history, shaping the nation’s social, economic, and political landscape. This comprehensive post details the history of slavery in the United States, illustrated with maps that depict the spread and eventual abolition of this brutal institution.
The first Africans brought to North America arrived in the early 17th century, primarily to the English colonies in Virginia and Maryland. By 1750, approximately 145,000 slaves were working in Maryland and Virginia, with an additional 40,000 in South Carolina. Despite these smaller initial numbers, the North American slave population grew rapidly through natural increase, resulting in a significant rise in the enslaved population over time.
The Spread of Slavery
As the United States expanded, so did the institution of slavery. The following map, create by lincolnmullen.com illustrates the spread of slavery across the United States from 1790 to 1860, highlighting how slavery became entrenched in various regions:
By the late 18th century, the United States was home to about 700,000 enslaved people. The invention of the cotton gin in 1793 significantly increased the demand for slave labor in the southern states, where cotton plantations became highly profitable. This demand led to a dramatic increase in the number of enslaved Africans brought to the United States.

The following map, created by radicalcartography.net depicts the peak number of slaves in various regions, with the size of each dot representing the number of enslaved people in each 250-square-mile cell.

The Abolition of Slavery
The abolition of slavery in the United States was a long and tumultuous process marked by significant legislative and social milestones. The movement to end slavery gained momentum in the 19th century, leading to the Civil War and the eventual emancipation of all enslaved people.
Early Efforts and Legislative Actions
Northwest Ordinance (1787): This legislation prohibited slavery in the Northwest Territory, setting a precedent for future states to follow. It was an early attempt to limit the spread of slavery into new territories.
Missouri Compromise (1820): This compromise allowed Missouri to enter the Union as a slave state while Maine entered as a free state, maintaining the balance of power between slave and free states. It also prohibited slavery in the Louisiana Territory north of the 36° 30′ latitude line.
Compromise of 1850: This series of laws included the Fugitive Slave Act, which required escaped slaves to be returned to their owners, even if they were found in free states. It also admitted California as a free state and allowed new territories to decide the issue of slavery by popular sovereignty.
The Civil War and Emancipation
The Civil War (1861-1865) was the pivotal conflict that led to the abolition of slavery. Several key events and legislative actions during and after the war were crucial in ending slavery:
Emancipation Proclamation (1863): Issued by President Abraham Lincoln, this executive order declared all slaves in Confederate states to be free. While it did not immediately free all enslaved people, it was a significant step toward abolition and altered the course of the war by adding a moral imperative to the Union cause.
13th Amendment (1865): Ratified in December 1865, this amendment to the U.S. Constitution formally abolished slavery throughout the United States. It stated, “Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States, or any place subject to their jurisdiction.”
