Original Six era

The Great Depression and the onset of World War II took a toll on the league. The Pirates became the Philadelphia Quakers in 1930, then folded a year later. The Senators likewise became the St. Louis Eagles in 1934, also lasting only a year. The Maroons did not survive, as they suspended operations in 1938. The Americans were suspended in 1942 due to a lack of available players, and they were never reactivated.

For the 1942–43 season, the NHL was reduced to six teams: the Boston Bruins, the Chicago Black Hawks, the Detroit Red Wings, the Montreal Canadiens, the New York Rangers, and the Toronto Maple Leafs, a line-up, often referred to as the " Original Six ", that would remain constant for the next 25 years. In 1947, the league reached an agreement with the Stanley Cup trustees to take full control of the trophy, allowing it to reject challenges from other leagues that wished to play for the Cup.

In 1945, Maurice "Rocket" Richard became the first player to score 50 goals, doing so in a 50-game season. Richard later led the Canadiens to five consecutive titles between 1956 and 1960, a record no team has matched.

In 1948, Asian Canadian Larry Kwong became the first Asian player in the NHL by playing for the New York Rangers. In 1958, Willie O'Ree became the first black player in the league's history when he made his debut with the Boston Bruins.
