# Timeline of the National Hockey League

The following is a complete history of organizational changes in the National Hockey League (NHL). The NHL was founded in 1917 as a successor to the National Hockey Association (NHA), starting out with four teams from the predecessor league, and eventually grew to thirty-two in its current state. The NHL has expanded and contracted numerous times throughout its history, including in 1979 when four teams were added from the World Hockey Association (WHA).

## 1917–1942: Early years
### Four/three teams (1917–19)

The four teams that began the inaugural NHL season were the Montreal Canadiens, the Montreal Wanderers, the original Ottawa Senators, and the Toronto Arenas. However, after completing four games, the Wanderers withdrew from the league due to their arena burning down, and the NHL continued that season and the next with only three teams.
* Withdrew after four games into the 1917–18 season §
1917–18 to 1918–19 NHL teams :
| Montreal Canadiens | Montreal Wanderers § | Ottawa Senators | Toronto Arenas |

### Four teams (1919–24)

In its third season, 1919–20, the NHL underwent its first expansion, adding the Quebec Bulldogs. Toronto changed its name to Toronto St. Patricks.
* First season in the NHL *
1919–20 NHL teams :
| Montreal Canadiens | Ottawa Senators | Quebec Bulldogs * | Toronto St. Patricks |

#### 1920: Quebec relocates to Hamilton

For the 1920–21 season, Quebec relocated to Hamilton and changed their name, becoming the Hamilton Tigers.
1920–21 to 1923–24 NHL teams :
| Hamilton Tigers | Montreal Canadiens | Ottawa Senators | Toronto St. Patricks |

### Six teams (1924–25)

Two new teams joined the NHL in its eighth season, the Boston Bruins, the first expansion team in the United States, and the Montreal Maroons.
| First season in the NHL * | Last season in the NHL † |
1924–25 NHL teams :
| Boston Bruins * | Montreal Canadiens | Ottawa Senators |
| Hamilton Tigers † | Montreal Maroons * | Toronto St. Patricks |

### Seven teams (1925–26)

The next season, the NHL added two new teams, the Pittsburgh Pirates and the New York Americans. The Americans were stocked by purchasing the contracts of the Hamilton Tigers players, and the Tigers franchise was subsequently revoked by the league.
* First season in the NHL *
1925–26 NHL teams :
| Boston Bruins | Montreal Maroons | Pittsburgh Pirates * | Toronto St. Patricks |
| Montreal Canadiens | New York Americans * | Ottawa Senators | |

### Ten teams (1926–31)

The NHL continued to expand the following 1926–27 season, adding the Chicago Black Hawks, the Detroit Cougars, and the New York Rangers, growing to ten teams, thus more than doubling its size in its first decade of existence. The league realigned into two divisions: the American Division and the Canadian Division. Despite its name, the Canadian Division contained at least one team based in the U.S. throughout its existence. At the same time, the Stanley Cup was contested between two NHL teams for the first time instead of at least one from an outside league.
Midway through the 1926–27 season, the Toronto St. Patricks were sold and renamed the Toronto Maple Leafs, however the league ruled the team must use the St. Patricks name until season's end.
* 1926–27 was the first season in the NHL *
1926–27 to 1929–30 NHL teams :
| Canadian Division | American Division |
| Montreal Canadiens | Boston Bruins |
| Montreal Maroons | Chicago Black Hawks * |
| New York Americans | Detroit Cougars * |
| Ottawa Senators | New York Rangers * |
| Toronto St. Patricks/Maple Leafs | Pittsburgh Pirates |

#### 1930: Pittsburgh relocates to Philadelphia

For the 1930–31 season, the Pirates moved from Pittsburgh to Philadelphia, becoming the Philadelphia Quakers, and Detroit was renamed the Detroit Falcons.
| Last season before hiatus, rejoined NHL later ^ | Last season in the NHL † |
1930–31 NHL teams :
| Canadian Division | American Division |
| Montreal Canadiens | Boston Bruins |
| Montreal Maroons | Chicago Black Hawks |
| New York Americans | Detroit Falcons |
| Ottawa Senators ^ | New York Rangers |
| Toronto Maple Leafs | Philadelphia Quakers † |

### Eight teams (1931–32)

After fourteen seasons of steady expansion, the NHL contracted to eight teams, dropping the Philadelphia Quakers and the original Ottawa Senators for the 1931–32 season.
1931–32 NHL teams :
| Canadian Division | American Division |
| Montreal Canadiens | Boston Bruins |
| Montreal Maroons | Chicago Black Hawks |
| New York Americans | Detroit Falcons |
| Toronto Maple Leafs | New York Rangers |

### Nine teams (1932–35)

For the 1932–33 season, after missing one season, the original Ottawa Senators rejoined the NHL, and the Detroit Falcons were renamed the Detroit Red Wings.
* Rejoined NHL *
1932–33 to 1933–34 NHL teams :
| Canadian Division | American Division |
| Montreal Canadiens | Boston Bruins |
| Montreal Maroons | Chicago Black Hawks |
| New York Americans | Detroit Red Wings |
| Ottawa Senators * | New York Rangers |

* Last season in the NHL †
1934–35 NHL teams :
| Canadian Division | American Division |
| Montreal Canadiens | Boston Bruins |
| Montreal Maroons | Chicago Black Hawks |
| New York Americans | Detroit Red Wings |
| St. Louis Eagles † | New York Rangers |
| Toronto Maple Leafs | |

### Eight teams (1935–38)

The Eagles folded after one season, and the NHL was once again an eight-team league for three seasons.
* Withdrew after the 1937–38 season †
1935–36 to 1937–38 NHL teams :
| Canadian Division | American Division |
| Montreal Canadiens | Boston Bruins |
| Montreal Maroons † | Chicago Black Hawks |
| New York Americans | Detroit Red Wings |
| Toronto Maple Leafs | New York Rangers |

### Seven teams (1938–42)

The Montreal Maroons withdrew from the league for the 1938–39 season, further reducing the number of teams in the NHL to seven, shrinking to the size the league was in 1925–26. Play continued for four seasons with seven teams, with one single league table instead of any conference or divisions.
1938–39 to 1941–42 NHL teams :
| Boston Bruins | Detroit Red Wings | New York Rangers | Toronto Maple Leafs |
| Chicago Black Hawks | Montreal Canadiens | New York Americans | |

#### 1941: The Americans change their name

The New York Americans changed their name to the Brooklyn Americans for the 1941–42 season, their last.
* Folded after the 1941–42 season †
1938–39 to 1941–42 NHL teams :
| Boston Bruins | Chicago Black Hawks | Montreal Canadiens | Toronto Maple Leafs |
| Brooklyn Americans † | Detroit Red Wings | New York Rangers | |

## 1942–1967: Original Six era

The 1942–43 season saw the folding of the Brooklyn Americans and ushered in an unprecedented era of franchise stability in the NHL, which lasted without any organizational changes for twenty-five seasons. Eventually, the six teams that competed in the league during this period would come to be known as the Original Six.
Original Six: 1942–43 to 1966–67 NHL teams :
| Boston Bruins | Detroit Red Wings | New York Rangers |
| Chicago Black Hawks | Montreal Canadiens | Toronto Maple Leafs |

## 1967–1991: Expansion era
### Twelve teams (1967–70)

The 1967 expansion doubled the number of teams in the league, with an upfront expansion fee of $2 million each ($18.3 million today). For the 1967–68 season, six new teams were added to the NHL: the California Seals, the Los Angeles Kings, the Minnesota North Stars, the Philadelphia Flyers, the Pittsburgh Penguins, and the St. Louis Blues.
Within a month into their first season, the California Seals became the Oakland Seals.
* All Original Six teams were placed in the East Division
* All 1967 expansion teams were placed in the West Division
1967–68 to 1969–70 NHL teams :
| East Division | West Division |
| Boston Bruins | Los Angeles Kings |
| Chicago Black Hawks | Minnesota North Stars |
| Detroit Red Wings | Oakland Seals |
| Montreal Canadiens | Philadelphia Flyers |
| New York Rangers | Pittsburgh Penguins |
| Toronto Maple Leafs | St. Louis Blues |

### Fourteen teams (1970–72)

The Oakland Seals were renamed the Bay Area Seals for two games before changing their name again to the California Golden Seals for their fourth season in 1970–71. The same season the NHL added two new teams, the Buffalo Sabres and the Vancouver Canucks, paying an expansion fee of $6 million each ($47.1 million today). The Sabres and the Canucks were placed in the East (partially as an effort to provide greater balance between the divisions, and also so they would have rivalries with the other two Canadian teams), while the Chicago Black Hawks moved to the West.
* 1970–71 was the first season in the NHL *
1970–71 to 1971–72 NHL teams :
| East Division | West Division |
| Boston Bruins | California Golden Seals |
| Buffalo Sabres * | Chicago Black Hawks |
| Detroit Red Wings | Los Angeles Kings |
| Montreal Canadiens | Minnesota North Stars |
| New York Rangers | Philadelphia Flyers |
| Toronto Maple Leafs | Pittsburgh Penguins |
| Vancouver Canucks * | St. Louis Blues |

### Sixteen teams (1972–74)

Two more teams joined for the 1972–73 NHL season, the New York Islanders and the Atlanta Flames. With the competing World Hockey Association (WHA) starting that same season, the NHL was not able to raise its expansion fee from the price of two years earlier, $6 million ($43.7 million today), with the Islanders paying an additional $5 million ($36.4 million today) to the New York Rangers for infringing on their territory. The Islanders were placed in the East and the Flames were placed in the West.
* 1972–73 was the first season in the NHL *
1972–73 to 1973–74 NHL teams :
| East Division | West Division |
| Boston Bruins | Atlanta Flames * |
| Buffalo Sabres | California Golden Seals |
| Detroit Red Wings | Chicago Black Hawks |
| Montreal Canadiens | Los Angeles Kings |
| New York Islanders * | Minnesota North Stars |
| New York Rangers | Philadelphia Flyers |
| Toronto Maple Leafs | Pittsburgh Penguins |
| Vancouver Canucks | St. Louis Blues |

### Eighteen teams (1974–78)

Two more teams joined for the 1974–75 NHL season, the Washington Capitals and the Kansas City Scouts, but the ongoing competition from the WHA meant that the overall revenue stream of the NHL had not improved, so the league kept the expansion fee for new owners at the $6 million ($37.1 million today) of two years and four years earlier. The earnings situation for the new franchises was so poor that (at least) the Capitals were able to negotiate a reduction to a total fee of $2.85 million ($17.6 million today).
With 18 teams, the league realigned into four divisions and two conferences. The teams were mixed up regardless of North American geography, and thus the new conferences and divisions were not named after geographical references. The East Division became the Prince of Wales Conference and consisted of the Adams Division and Norris Division. The West Division became the Clarence Campbell Conference and consisted of the Patrick Division and Smythe Division.
* 1974–75 was the first season in the NHL *
1974–75 to 1975–76 NHL teams :
| Wales | Wales | Campbell | Campbell |
| Adams | Norris | Patrick | Smythe |
| Boston Bruins | Detroit Red Wings | Atlanta Flames | Chicago Black Hawks |
| Buffalo Sabres | Los Angeles Kings | New York Islanders | Kansas City Scouts * |
| California Golden Seals | Montreal Canadiens | New York Rangers | Minnesota North Stars |
| Toronto Maple Leafs | Pittsburgh Penguins | Philadelphia Flyers | St. Louis Blues |
| | Washington Capitals * | | Vancouver Canucks |

### 1976: Two teams relocate

Going into the 1976–77 NHL season, the California Golden Seals relocated to become the Cleveland Barons, and the Kansas City Scouts moved to become the Colorado Rockies.
* Dissolved after the 1977–78 season †
1976–77 to 1977–78 NHL teams :
| Wales | Wales | Campbell | Campbell |
| Adams | Norris | Patrick | Smythe |
| Boston Bruins | Detroit Red Wings | Atlanta Flames | Chicago Black Hawks |
| Buffalo Sabres | Los Angeles Kings | New York Islanders | Colorado Rockies |
| Cleveland Barons † | Montreal Canadiens | New York Rangers | Minnesota North Stars |
| Toronto Maple Leafs | Pittsburgh Penguins | Philadelphia Flyers | St. Louis Blues |
| | Washington Capitals | | Vancouver Canucks |

### Seventeen teams (1978–79)

For the first time since the 1942–43 season, the NHL contracted, merging the Cleveland Barons into the Minnesota North Stars. The North Stars then took the Barons' place in the Adams Division.
1978–79 NHL teams :
| Wales | Wales | Campbell | Campbell |
| Adams | Norris | Patrick | Smythe |
| Boston Bruins | Detroit Red Wings | Atlanta Flames | Chicago Black Hawks |
| Buffalo Sabres | Los Angeles Kings | New York Islanders | Colorado Rockies |
| Minnesota North Stars | Montreal Canadiens | New York Rangers | St. Louis Blues |
| Toronto Maple Leafs | Pittsburgh Penguins | Philadelphia Flyers | Vancouver Canucks |
| | Washington Capitals | | |

### Twenty-one teams (1979–91)

Following seven seasons of revenue draining competition, the NHL–WHA merger was completed for the start of the 1979–80 NHL season. Four teams came over from the WHA, paying an expansion fee of $7.5 million each ($31.5 million today). These new NHL teams were the Edmonton Oilers, Hartford Whalers, Quebec Nordiques, and the original Winnipeg Jets. This also doubled the number of Canadian teams in the league. Standing at 21 teams for twelve seasons, this was one of the longer periods of league stability, though surpassed by twenty-five seasons of the Original Six, when no additions, moves, nor name changes occurred.
The Nordiques were placed in the Adams Division, the Whalers in the Norris, and the Oilers and the Jets in the Smythe. The Washington Capitals moved from the Norris to the Patrick Division. The divisions were effectively meaningless as all teams played a balanced schedule and each round of the playoffs was re-seeded by league point standings rather than divisional.

| | Washington Capitals | | |

## 1991–2017: Further expansion

In 1990, the owners developed a plan to expand the NHL to 28 teams within a decade. The plan was enacted, creating ten years of rapid expansion and relocation in the NHL. While the pace of expansion and relocation slowed after the 1999–2000 season, growth and change continued to be a normal development.

### Twenty-two teams (1991–92)

The 1991–92 season saw the addition of the San Jose Sharks, paying an expansion fee of $45 million ($100.7 million today). The Sharks were placed in the Smythe Division with the other West Coast teams.

The Minnesota North Stars relocated, becoming the Dallas Stars.
The league changed the conference names from Wales and Campbell to Eastern and Western, respectively, and changed the division names from Adams, Patrick, Norris, and Smythe to Northeast, Atlantic, Central, and Pacific, respectively.
Finally, the league realigned several teams. With the expansion Mighty Ducks joining the Pacific Division in the Western Conference, the original Winnipeg Jets left the Pacific for the Central, the Tampa Bay Lightning left the Central Division and Western Conference for the Atlantic and the Eastern, respectively, and the Pittsburgh Penguins left the Atlantic Division for the Northeast to make room for the expansion Florida Panthers.

The league also realigned to a strictly geographic six-division structure, with three per conference. The Eastern Conference had the Atlantic, Northeast, and Southeast divisions, while the Western Conference had the Central, Northwest, and Pacific divisions. The expansion Predators were placed in the Central Division. The Toronto Maple Leafs were the only team to switch conferences, moving from the Western and the Central Division to the Eastern and the Northeast Division, rejoining classic East Division and Adams Division rivals for the first time since the respective 1973–74 and 1980–81 seasons.

The Blue Jackets were placed in the Central Division and the Wild in the Northwest so that all six divisions would each have five teams.
For the next 17 seasons, the NHL maintained 30 teams, the second longest period of membership stability in its history, the first being the Original Six.

### 2013 realignment

The 2011 relocation of the former Atlanta Thrashers franchise to the Winnipeg Jets prompted the league to discuss realignment. However, disagreement between the NHL Board of Governors and the National Hockey League Players' Association (NHLPA) caused it to be pushed to 2013.
On December 5, 2011, the NHL Board of Governors originally approved a conference realignment plan to move from a six-division setup to a four-conference structure. However, on January 6, 2012, the National Hockey League Players' Association (NHLPA) rejected that proposed realignment. A new joint NHL-NHLPA plan was proposed in February 2013 as a modification of the previous plan with both the Columbus Blue Jackets and Detroit Red Wings moving to the East and the Winnipeg Jets moving to the West. The NHLPA officially gave its consent to the NHL's proposed plan on March 7, and then the NHL's Board of Governors approved the realignment on March 14, to be implemented prior to the 2013–14 season. The league then announced the names of the divisions on July 19: the two eight-team divisions in the Eastern Conference would be the Atlantic Division and the Metropolitan Division, and the two seven-team divisions in the Western Conference would be the Central Division and the Pacific Division.

However, it has also seen the Arizona Coyotes indefinitely suspend operations following the 2023–24 season, with the team's hockey assets, including its roster and coaches, being transferred to the newly-founded Utah franchise.

### Thirty-one teams (2017–2021)

On June 22, 2016, the Board of Governors voted 30–0 to add an expansion franchise in Las Vegas for the 2017–18 season, charging an expansion fee of $500 million ($634.8 million today). The Vegas Golden Knights joined the Pacific Division of the Western Conference.

### 2020–21: COVID-19 pandemic

Due to the COVID-19 pandemic, which delayed the conclusion of the 2019–20 season and delayed and shortened the 2020–21 season, the NHL adopted a temporary divisional alignment for 2020–21. The primary considerations acknowledged by the league were the ongoing restrictions and quarantine requirements affecting the ability of its teams to cross the Canada–United States border. As a result, on December 20, 2020, the league announced it had temporarily suspended the Eastern and Western Conferences and realigned to four non-conference divisions: North, East, Central, and West. The North Division consisted of all seven Canadian teams and was the first all-Canadian division since the league first expanded into the United States in 1924. The regular season lasted 56 games and consisted solely of intra-divisional play.
2020–21 NHL teams :
| North | East | Central | West |

| Winnipeg Jets | Pittsburgh Penguins | Nashville Predators | San Jose Sharks |
| | Washington Capitals | Tampa Bay Lightning | Vegas Golden Knights |

### Thirty-two teams (2021–2024)

On December 4, 2018, Seattle was announced as the location of a thirty-second franchise to begin play in the 2021–22 season, with an expansion fee of $650 million. The league reverted to its pre-COVID-19 divisions in 2021. Under the realignment of those divisions that was announced prior to the pandemic, the expansion Seattle Kraken were placed in the Pacific Division, while the Arizona Coyotes returned to the Central Division.

### League expands to Utah, Coyotes suspend operations (2024–present)

On April 18, 2024, the Arizona Coyotes were deactivated, and its players and personnel were transferred to the Utah Hockey Club. Under the original conditions, the Coyotes franchise would have been reactivated if a suitable arena was built in Arizona by 2029. After the Arizona State Land Department cancelled a June 2024 auction for a parcel of land that Coyotes owner Alex Meruelo intended to purchase as a site for a new arena, he relinquished his rights as the team's owner on July 10. As of July 2024, the league has not yet indicated whether the Arizona franchise will now fold outright, hold the rights to the Coyotes and wait for a potential expansion team, and/or whether its history, records and/or intellectual property will be transferred to the Utah Hockey Club and/or split between Utah and the current Winnipeg Jets.

## Potential future expansion

After the 2000–01 season, when the NHL completed its 1990 plan to grow to 30 teams, the league made statements to the effect that no further expansion or even relocation was planned for the foreseeable future. As shown above, no changes occurred until a relocation in the 2011–12 season, followed by semi-regular growth and change.
There have been rumors and talks of potential new sites for existing or new teams in various locations in the United States and Canada, including Atlanta, Cincinnati, Cleveland, Hartford, Houston, Kansas City, Milwaukee, Oklahoma City, Omaha, Phoenix, Portland (Oregon), Quebec City, San Diego, Saskatoon, and a second Southern Ontario team (although the league has actively blocked all of the Southern Ontario efforts to date, including in Hamilton, citing territorial concerns with the Buffalo Sabres and Toronto Maple Leafs).
