Westward Expansion and the Old West
The original thirteen colonies of the United States were settled along the east coast of North America. For many years, few colonists went beyond the Appalachian Mountains. However, as the country gained independence and continued to grow, more land was needed. The country began to expand into the western frontier.

In 1700 there were around 250,000 colonists living in the American colonies. By 1775, this number had grown to 2.5 million. Many people wanted new land to farm and hunt. They began to move west of the Appalachians.
One of the first areas settled was the Northwest Territory. This area today makes up the states of Indiana, Ohio, Michigan, Wisconsin, and Illinois. Daniel Boone led settlers across the Cumberland Gap and into Kentucky.
In 1803, President Thomas Jefferson bought the Louisiana Territory from the French for $15 million. This was a huge area of land west of the Mississippi River. It nearly doubled the land size of the United States. President Jefferson sent explorers Lewis and Clark to learn more about this vast frontier.
Many people in the United States believed it was the country's destiny to expand westward all the way to the Pacific Ocean. This belief became known as the Manifest Destiny.
The United States continued to expand westward and gain land. After a war with Mexico over the rights to Texas, the country gained much of the southwest including the land of California. They also gained the Oregon Territory in a treaty from Great Britain.
Settling the West
Pioneers and settlers moved out west for different reasons. Some of them wanted to claim free land for ranching and farming from the government through the Homestead Act. Others came to California during the gold rush to strike it rich. Even others, such as the Mormons, moved west to avoid persecution.
As the first settlers and pioneers moved into the west, there was little government. The law was the local sheriff and people had to look to protect themselves against bandits and outlaws. During this time, gunslingers of the west such as Wild Bill Hickok and Jesse James became famous.
End of the Frontier
In 1890, the US government announced that the west had been explored. The country now had 44 states. Only Utah, New Mexico, Oklahoma, and Arizona had not been admitted as states from today's contiguous 48 states.
