History is the study of the human past. Historians study records of conditions or events of a particular time and place. The United States of America is at once a very new nation and a very old nation. The first settlers - Asian hunters and nomads - reached North America about 30,000 years ago. However, the United States of America did not come into being until 1776 with the Declaration of Independence. The history of the United States is the story of many different peoples who together compose the United States of America. Since the first Europeans arrived in 1492, millions of people from many different countries have entered the United States and made the country their new home.Credits :Boundless Book (Creative Commons Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0))Readium is available under BSD 3-Clause license
