Long ago, many people were not free. 

Many people worked on big farms. They grew crops like rice and tobacco. In the South, many people were held in slavery. This made the South very different from the North. 
Some people fought to end slavery. They wanted everyone to be free. Many black soldiers even fought in wars. They were very brave. 
After a big war, laws finally changed. A new rule said slavery was not allowed. This was a big step for the country. People worked hard to make things better.
Slavery was a system where people were not free. 
In the early colonies, slavery was found in many places. In the North, people often worked in cities. They worked as servants or craftsmen. In the South, many people worked on large farms. They grew crops like tobacco and rice. 
People had many different ideas about slavery. Some leaders in the North wanted to end it. This was called the abolition movement. Many Black people fought for freedom during the American Revolution. 
Arguments over slavery grew very strong. This led to the Civil War. After the war, the country changed its laws. The Thirteenth Amendment was passed in 1865. This law ended slavery in the United States.
Slavery was a legal system in the United States that treated people as property. 

In the early years, the way slavery worked depended on where people lived. In the Northern colonies, many enslaved people lived in cities. They often worked as house servants, craftsmen, or laborers on the docks. By 1703, over 42% of households in New York City held enslaved people. In the South, the system was built around large farms called plantations. 

History shows that many people fought to change these laws. During the American Revolution, some leaders called the slave trade cruel. The colonies even began to ban the trade of people from Africa. In 1808, Congress passed a law to ban this trade entirely. 
As the United States grew, the debate over slavery became very intense. The U.S. Constitution had rules that made the issue even more complicated. The Three-Fifths Clause gave slave states more political power in Congress. There was also a Fugitive Slave Clause that helped owners find people who escaped. 

This tension eventually led to the American Civil War. The war began when Confederate forces attacked Fort Sumter in South Carolina. During the fighting, some rules were made to end slavery in many places. 

Slavery in the United States was a legal system of human chattel slavery. This system treated people as property that could be bought, sold, or given away. It primarily enslaved people of African ancestry. This institution was prevalent from the founding of the United States in 1776 until 1865. However, slavery existed in the Americas during European colonization long before the nation was formed. In the British colonies, it was practiced as early as 1526. 
The mechanism of slavery was built into the law and social structures. Under these laws, children were born into slavery. Enslaved people were legally classified as property rather than citizens. This status meant they had no rights to speak or vote. The system also influenced how political power was measured. The Three-Fifths Clause in the U.S. Constitution (1789) counted enslaved people as three-fifths of a person for representation in Congress. This gave slave states more political influence. Additionally, the Fugitive Slave Clause required that escaped people be returned to their owners. 
Slavery functioned differently depending on the geographic region. In the Northern colonies, enslaved people often lived in cities. They worked as house servants, artisans, or laborers on docks. For example, in 1703, over 42% of New York City households held enslaved people. In the South, the system was based on an agricultural economy. Planters used enslaved labor to grow commodity crops. In the Upper South, these crops included indigo, rice, and tobacco. In the Deep South, the expansion of the cotton industry changed the economy. 
The invention of the cotton gin significantly altered the scale of slavery. This machine increased the demand for labor in the Deep South. As a result, more than one million enslaved people were sold from the Upper South to the Deep South. By the time the system reached its peak, the total enslaved population in the South reached four million. This massive shift created deep divisions between the North and the South. The country became increasingly polarized over the expansion of slavery into new territories. 
History shows a long struggle regarding the legality of the Atlantic slave trade. During the American Revolution, some groups called the trade "wicked, cruel and unnatural." Many colonies began to outlaw the importation of slaves during this period. In 1808, the U.S. Congress officially banned the slave trade. Despite this ban, smuggling remained common on the high seas. The U.S. Revenue Cutter Service, which is now the Coast Guard, had to enforce the ban.
Many people fought for abolition and freedom during the revolutionary era. About 20,000 enslaved people fought in the American Revolution. Some leaders, like George Washington, authorized freedom for those who fought in the Continental Army. In the North, abolitionist laws passed in most states during and after the Revolution. By 1805, most Northern states had abolished slavery to some degree. This process was often gradual, sometimes involving intermediary statuses like unpaid indentured servitude. 
Political crises arose as the United States acquired new lands. The Louisiana Purchase and the Mexican Cession became major points of conflict. Leaders argued about whether slavery should be allowed in these Western territories. The Kansas-Nebraska Act of 1854 allowed for the legal expansion of slavery into these areas. This overturned previous policies of containment. By 1850, the tension was so high that the South threatened to secede from the Union. 
The conflict eventually led to the American Civil War. The war began after Confederate forces attacked Fort Sumter in South Carolina. During the war, Union measures like the Emancipation Proclamation helped end slavery in many places. On December 6, 1865, the Thirteenth Amendment was ratified. This amendment prohibited slavery and involuntary servitude, except as punishment for a crime. Although slavery ended, many social and economic functions continued through systems like sharecropping and segregation.
