National squad

A national sport is considered to be an intrinsic part of the culture of a nation. Some sports are de facto (not established by law) national sports, as baseball is in the United States and Gaelic games are in the Republic of Ireland, while others are de jure (established by law) national sports, as lacrosse and ice hockey are in Canada. These sports do not have to be necessarily the most played or most followed, which would be either football, baseball or basketball in all but a few countries are widely considered to be important to the significant for its culture.
