The history of Native Americans - or American Indians - is unique, tragic and at the same time full of optimism. It is unique because the Indians were indigenous to the American continent and experienced all stages of its settling by Europeans. 

Nowadays, Native Americans are full-fledged citizens of the United States, who are proud that they are Americans. However, they are equally proud of their own cultural heritage, and, as hard as it is in the modern world, they are trying to protect and preserve it.
