Lacrosse is a team sport played with a lacrosse stick and a lacrosse ball. It is the oldest organized sport in North America, with its origins dating back to the 12th century. The game was originally played by Native American tribes in the eastern woodlands of the United States and Canada. The Iroquois Confederacy, in particular, is credited with developing the modern game of lacrosse. The game was played for recreational, ceremonial, and spiritual purposes, and it was often used to settle disputes between tribes.
