Lacrosse is the oldest team sport in North America. It may have developed as early as the 1100s, but since then it has seen many modifications The modern Ojibway verb 'to play Lacrosse' is baaga'adowe (Baggataway).

In Native society the sport was used as a religious ritual. Games could be played on a pitch over a mile wide and sometimes lasted for days. Early lacrosse balls were made out of deerskin, clay, stone, and sometimes wood. Lacrosse has played a significant role in the community and religious life of tribes across the continent for many years. Early lacrosse was characterized by deep spiritual involvement, befitting the spirit of combat in which it was undertaken. Those who took part did so in the role of warriors, with the goal of bringing glory and honor to themselves and their tribes. The game was said to be played "for the Creator."
