The United States is rich in resources.
Its farmlands produce corn, soybeans,
wheat, cotton, and many other crops
that are sold to countries all over the
world. The United States is among the
world’s leading producers of several
minerals, including copper, silver, zinc,
gold, coal, petroleum (oil), and natural
gas. Forestry and fishing are important
industries, too.
History
The first people to live in the Americas
were the Native Americans. The first
Native Americans probably came from
Asia beginning about 60,000 years ago.
By the 1400s there were about 200 different
groups of Native Americans living
on the land that became the United
States.
The history of the Americas changed
forever in 1492 when Christopher
Columbus sailed there from Spain.
After Columbus’ voyage, many other
explorers and settlers came from
Europe. The Native Americans suffered.
Some died from diseases carried by the
Europeans. Others died fighting the
Europeans.
Colonies
The first lasting European settlement in
what is now the United States was Saint
Augustine, Florida. It was built by the
Spanish in 1565. The Spanish made
Florida and what is now the southwestern
United States into colonies. The

English, the French, and the Dutch
(people from the Netherlands) also set
up colonies.
The English founded their first lasting
settlement in North America in 1607. It
was Jamestown, in what was later the
state of Virginia. Then the English built
other settlements and seized colonies
from the Dutch. Soon there were 13
English colonies along the Atlantic
coast.
In 1700 about 250,000 people lived in
the 13 colonies. By 1760 the population
was nearly 1.7 million. Many of the
newcomers were Africans who were
brought to work as slaves, especially in
the South.
American Revolution
In the 1760s the British government
started to tighten its control over the
colonies. Parliament, the British legislature,
forced the colonists to pay new
taxes. The colonists protested. Tension
built up between Britain and the colonies.
In 1775 fighting broke out between
colonists and British forces in Concord
and Lexington, Massachusetts. These
battles began the American Revolution.
On July 4, 1776, the colonies approved
the Declaration of Independence. This
document made the colonies into the
United States.
The American Revolution continued
until the British surrendered in 1781. By
signing a treaty in 1783, Britain
accepted the independence of the
United States.
The New Country
In 1787 representatives from the states
met in Philadelphia, Pennsylvania. The
meeting produced a document that outlined
a new government. The document
was the U.S. Constitution. It took effect

in 1789. GeorgeWashington became
the country’s first president.
The United States soon began to grow.
In 1803 President Thomas Jefferson
bought the Louisiana Territory from
France. The purchase added a vast area
west of the Mississippi River to the
United States. In 1819 the United States
acquired Florida from Spain.
Texas became a state in 1845. The
United States and Mexico disagreed over
the border between Texas and Mexico.
In 1846 the countries went to war. The
MexicanWar lasted until 1848. The
United States defeated Mexico and took
over California and the rest of the
Southwest.
CivilWar and Reconstruction
In the middle of the 1800s slavery
divided the United States. Southern
farms depended on slave labor, but
many Northerners were strongly against
slavery. In 1860 Abraham Lincoln was
elected president. His party, the Republicans,
opposed slavery. After Lincoln’s
election, the Southern states began to
secede (withdraw) from the United
States. They formed their own government.
It was called the Confederate
States of America, or the Confederacy.
In 1861 war broke out between the
U.S. government, called the Union,
and the Confederacy. This was the
American Civil War. The Confederacy
won most of the early battles, but by
1864 the Union was winning. In 1865
the Confederate general Robert E. Lee
surrendered.
The period after the CivilWar is known
as Reconstruction. The Republican leaders
of Congress passed harsh laws to
punish the South. These laws angered
many Southern whites. And even
though the war had ended slavery, African
Americans still struggled. Many
became poor farmworkers.
Growth of the Country

United States grew as more people
