The history of the United States is a history of people on the move. The Native Americans came to
North America thousands of years ago. Some of them built villages and stayed there, but many moved from
place to place.
The first travelers from Europe came to live in an unknown land. At first, they stayed near the coast,
but then a few brave men went west, far into the country. Two of them were Meriwether Lewis and William
Clark. In 1804, they started on their long journey from St. Louis, Missouri, to the Pacific Ocean. They
followed the Missouri River west, went across the Rocky Mountains, and followed the Columbia River to the
Pacific. Then, they turned around, and traveled back to St. Louis.
During the next 150 years, millions of poor people came from the old cities of Europe. They built the new
cities of US, and farmed the land. But they did not always stay in their new cities or on their farms. Many
people moved on, deeper and deeper into the new land. Some followed religious leaders (宗教领袖) like
Joseph Smith. He and his followers built Salt Lake City in Utah. Others went to look for gold. After the
California Gold Rush in 1849, San Francisco grew from a village to a city in only a few years.
People are still moving to the US and finding new homes there. Up to one million people come into the
US from Mexico in one year. At the same time, many more arrive from the Pacific nations and regions-from
the Philippines, Korea, Vietnam, Taiwan and also from Central and South America. The history of the US is
still on the move.
