Native Americans came from Asia. When English colonists came to the New World on board the "Mayflower" the native Americans met them and were very friendly and helped them a lot.
 Most native Americans were very peaceful. They often had special ceremonies with dances and music before they went hunting or fishing or when they began farming.

Native Americans songs and poems are a very important part of their traditions. Another famous tradition was smoking of a peace pipe. Many years ago Native American tribes lived in all parts of the USA now most of them live in poor lands to the west of Mississippi River. Many live in "reservations".
