History: The original inhabitants of North America were Native Americans and Inuit people. To trace the history of the United States, we must go back to the 15th century. Christopher Columbus's "geographical discovery" in 1492 opened up new areas for the emerging bourgeoisie. After that, European countries continuously immigrated to the Americas. In the first half of the 17th and 18th centuries, Britain established 13 British colonies along the Atlantic coast (which later became the main components of the United States when it gained independence). In the mid-18th century, a rift had emerged between Britain and the American colonies. On April 4, 1775, the first shot of the American Revolutionary War was fired in Lexington, north of Boston. On July 4, 1776, the Declaration of Independence was adopted in Philadelphia, establishing the United States of America. In 1783, the United States and Britain signed a treaty, ending the Revolutionary War. The American people overthrew British colonial rule and established an independent and sovereign bourgeois republic. The U.S. federal government was officially established in 1789. The American Civil War (1861–1865) took place domestically, abolishing slavery. After that, the U.S. economy developed rapidly: by the late 19th century, U.S. industrial production had become the world's largest. Since the 20th century, science and technology, cultural education, and production scale have been in a leading position worldwide, making the United States a world power. Between 1803 and 1959, the territory of the United States expanded from 13 states at independence to the current 50 states. Currently, the overseas territories of the United States include: Guam and the Eastern Samoa Islands in the Pacific; the Puerto Rican Islands in the Caribbean; the U.S. Virgin Islands, and so on.
