National Hockey Association
The National Hockey Association (NHA), initially the National Hockey Association of Canada Limited, was a professional ice hockey organization with teams in Ontario and Quebec, Canada. It is the direct predecessor of today's National Hockey League (NHL), and much of the business processes of the NHL today are based on the NHA. Founded in 1909 by Ambrose O'Brien, the NHA introduced 'six-man hockey' by removing the 'rover' position in 1911. During its lifetime, the league coped with competition for players with the rival Pacific Coast Hockey Association (PCHA), the enlistment of players for World War I and disagreements between owners. The disagreements between owners came to a head in 1917, when the NHA suspended operations in order to get rid of an unwanted owner, Eddie Livingstone.

The National Hockey League is a men’s professional ice hockey league in North America comprising 33 teams – 26 in the United States and 7 in Canada. The Stanley Cup, the oldest professional sports trophy in North America, is awarded annually to the league playoff champion at the end of each season. The NHL is one of the major professional sports leagues in the United States and Canada and is considered to be the top ranked professional ice hockey league in the world, with players from 17 countries as of the 2023–24 season. The International Ice Hockey Federation (IIHF) also views the Stanley Cup as one of the "most important championships available to the sport". The NHL is headquartered in Midtown Manhattan.
