Early years The National Hockey League (NHL) was established in 1917 as the successor to the
National Hockey Association (NHA). Founded in 1909, the NHA
began play in 1910 with seven teams in
Ontario and
Quebec, and was one of the first major leagues in professional ice hockey. However, by its
eighth season, a series of disputes with
Toronto Blueshirts owner
Eddie Livingstone led team owners of the
Montreal Canadiens, the
Montreal Wanderers, the
Ottawa Senators, and the
Quebec Bulldogs to hold a meeting to discuss the league's future. Realizing the NHA constitution left them unable to force Livingstone out, the four teams voted instead to suspend the NHA, and, on November 26, 1917, formed the National Hockey League.
Frank Calder was chosen as the NHL's first president, serving until his death in 1943. The Bulldogs were unable to play in the NHL, and the remaining owners founded the
Toronto Arenas to compete with the Canadiens, Wanderers and Senators. The first games were played on December 19, 1917. The
Montreal Arena burned down in January 1918, causing the Wanderers to cease operations, and the NHL continued on as a three-team league until the Bulldogs returned in 1919. in 1930, several years after it became the
de facto championship trophy for the NHL The NHL replaced the NHA as one of the leagues that competed for the Stanley Cup, an interleague competition at the time. Toronto won the first NHL title, and then defeated the
Vancouver Millionaires of the
Pacific Coast Hockey Association (PCHA) for the
1918 Stanley Cup. The Canadiens won the league title in 1919, but the series in the Stanley Cup Final against the PCHA's
Seattle Metropolitans was abandoned due to the
Spanish Flu epidemic. In 1924, Montreal won their first Stanley Cup as a member of the NHL. The
Hamilton Tigers won the regular season title in
1924–25, but refused to play in the championship series unless they were given a
C$200 bonus. The league refused and declared the Canadiens the league champion after they defeated the
Toronto St. Patricks (formerly the Arenas) in the two-game, total-goals NHL championship series. Montreal was then defeated by the
Victoria Cougars of the
Western Canada Hockey League (WCHL) in
1925. It was the last time a non-NHL team won the trophy, as the Stanley Cup became the
de facto NHL championship in 1926, after the WCHL ceased operation. The NHL embarked on a rapid expansion in the 1920s, adding the
Montreal Maroons and the
Boston Bruins in 1924, the latter being the first American team to join the league. The
New York Americans began play in 1925 after purchasing the assets of the Hamilton Tigers, and they were joined by the
Pittsburgh Pirates. The
New York Rangers were added in 1926, and the
Chicago Black Hawks (later changed to Blackhawks) and
Detroit Cougars (later known as the Red Wings) were added after the league purchased the assets of the defunct WCHL. A group purchased the Toronto St. Patricks in 1927 and renamed them the
Toronto Maple Leafs. In 1926, Native American
Taffy Abel became the first non-white player in the NHL and broke the league's colour barrier by playing for the New York Rangers. In 1934, the first
NHL All-Star Game was held, to benefit
Ace Bailey, whose career ended on a vicious hit by
Eddie Shore. The second was held in 1937, in support of
Howie Morenz's family when he died of a coronary embolism after breaking his leg during a game.
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. and the
New York Rangers in 1962|alt=Five men playing hockey in a crowded arena. 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.
Expansion era By the mid-1960s, the desire for a network television contract in the United States, coupled with concerns that the
Western Hockey League was planning to declare itself a major league and challenge for the Stanley Cup, spurred the NHL to undertake
its first expansion since the 1920s. The league doubled in size to 12 teams for the
1967–68 season, adding the
Los Angeles Kings, the
Minnesota North Stars, the
Philadelphia Flyers, the
Pittsburgh Penguins, the
California Seals, and the
St. Louis Blues. However, Canadian fans were outraged that all six teams were placed in the United States, so the league responded by adding the
Vancouver Canucks in
1970, along with the
Buffalo Sabres, both located along the
Canada–United States border. Two years later, the emergence of the newly founded
World Hockey Association (WHA) led the league to add the
New York Islanders and the
Atlanta Flames to keep the rival league out of those markets. In 1974, the
Washington Capitals and the
Kansas City Scouts were added, bringing the league up to 18 teams. The NHL fought the WHA for players, losing 67 to the new league in its first season of
1972–73, including the Chicago Black Hawks'
Bobby Hull, who signed a 10-year, $2.5 million contract with the
Winnipeg Jets, then the largest in hockey history. The league attempted to block the defections in court, but a counter-suit by the WHA led to a Philadelphia judge ruling the NHL's
reserve clause to be illegal, thus eliminating the elder league's monopoly over the players.
Wayne Gretzky played one season in the WHA for the
Indianapolis Racers (eight games) and the
Edmonton Oilers (72 games) before the Oilers joined the NHL for the
1979–80 season. Gretzky went on to lead the Oilers to win four Stanley Cup championships in
1984,
1985,
1987 and
1988, and set single-season records for goals (92 in
1981–82), assists (163 in
1985–86) and points (215 in 1985–86), as well as career records for goals (894), assists (1,963) and points (2,857). Also, in the mid to late 1990s, the Quebec Nordiques, original Winnipeg Jets, Hartford Whalers, and Minnesota North Stars relocated to Denver, Phoenix, Raleigh, and Dallas, respectively. In 2011, the Atlanta Thrashers relocated to Winnipeg, and the
Winnipeg Jets were revived. On July 21, 2015, the NHL confirmed that it had received applications from prospective ownership groups in
Quebec City and
Las Vegas for possible expansion teams, and on June 22, 2016, NHL Commissioner Gary Bettman announced the addition of a 31st franchise, based in Las Vegas and later named the
Vegas Golden Knights, into the NHL for the
2017–18 season. On December 4, 2018, the league announced a 32nd franchise in
Seattle, later named the
Seattle Kraken, which joined in the
2021–22 season. On April 18, 2024, the Arizona Coyotes suspended operations and sold their hockey assets, including players and other personnel, to a
new team in
Salt Lake City,
Utah. Two months after Utah's foundation, the Coyotes ceased their efforts to re-activate within the five-year window granted to do so, bringing the NHL back to 32 franchises.
Labour issues There have been four league-wide work stoppages in NHL history, all occurring since
1992. The first was
an April 1992 strike by the
National Hockey League Players' Association, which lasted for ten days but was settled quickly with all affected games rescheduled. A
lockout at the start of the
1994–95 season forced the league to reduce the schedule from 84 games to 48, with the teams playing only intra-conference games during the reduced season. With no new agreement in hand when the contract expired, league commissioner
Gary Bettman announced a
lockout of the players union and closed the league's head office for the
2004–05 season. However, its television audience was slower to rebound due to American cable broadcaster
ESPN's decision to drop its NHL coverage. The league's post-lockout agreement with
NBC gave the league a share of revenue from each game's advertising sales, rather than the usual lump sum paid up front for game rights. The league's annual revenues were estimated at $2.27 billion. The owners proposed reducing the players' share of hockey-related revenues from 57 percent to 47 percent. All games were cancelled up to January 14, 2013, along with the
2013 NHL Winter Classic and the
2013 NHL All-Star Weekend. On January 6, a tentative agreement was reached on a 10-year deal. On January 12, the league and the Players' Association signed a memorandum of understanding on the new deal, allowing teams to begin their training camps the next day, with a shortened 48-game season schedule that began on January 19.
Player safety issues Player safety has become a major issue in the NHL, with
concussions resulting from a hard hit to the head being the primary concern. Recent studies have shown how the consequences of concussions can last beyond player retirement. This has significant effects on the league, as elite players have suffered from the aftereffects of concussions (such as
Sidney Crosby being sidelined for approximately ten and a half months), which adversely affects the league's marketability. In December 2009,
Brendan Shanahan was hired to replace Colin Campbell, and was given the role of senior vice-president of player safety. Shanahan began to hand out suspensions on high-profile perpetrators responsible for dangerous hits, such as
Raffi Torres receiving 25 games for his hit on
Marian Hossa. To aid with removing high-speed collisions on icing, which had led to several potential career-ending injuries, such as to Hurricanes' defenceman
Joni Pitkanen, the league mandated hybrid no-touch icing for the
2013–14 NHL season. On November 25, 2013, ten former NHL players (Gary Leeman, Rick Vaive, Brad Aitken, Darren Banks, Curt Bennett, Richie Dunn, Warren Holmes, Bob Manno, Blair Stewart, and Morris Titanic) sued the league for negligence in protecting players from concussions. The suit came three months after the
National Football League agreed to pay former players US$765 million due to a player safety lawsuit.
Women in the NHL From 1952 to 1955,
Marguerite Norris served as president of the
Detroit Red Wings, being the first female NHL executive and the first woman to have her name engraved on the Stanley Cup. In 1992,
Manon Rhéaume became the first woman to play a game in any of the major professional North American sports leagues, as a goaltender for the
Tampa Bay Lightning in a preseason game against the
St. Louis Blues, stopping seven of nine shots. In 2016,
Dawn Braid was hired as the
Arizona Coyotes' skating coach, making her the first female full-time coach in the NHL. The first female referees in the NHL were hired in a test-run during the league's preseason prospect tournaments in September 2019. In 2016, the NHL hosted the
2016 Outdoor Women's Classic, an exhibition game between the
Boston Pride of the
National Women's Hockey League and
Les Canadiennes of the
Canadian Women's Hockey League, as part of the
2016 NHL Winter Classic weekend festivities. In 2019, the NHL invited four women from the US and Canadian Olympic teams to demonstrate the events in
All-Star skills competition before the
All-Star Game. Due to
Nathan MacKinnon choosing not to participate following a bruised ankle, Team USA's
Kendall Coyne Schofield competed in the Fastest Skater competition in his place, becoming the first woman to officially compete in the NHL's All-Star festivities. The attention led the NHL to include a
3-on-3 women's game before the
2020 All-Star Game. Rheaume returned to perform as a goaltender for the
2022 NHL All-Star Game's Breakaway Challenge. ==Teams==
