Expansion team
An expansion team is a new team in a sports league, usually from a city that has not hosted a team in that league before, formed with the intention of satisfying the demand for a local team from a population in a new area. Sporting leagues also hope that the expansion of their competition will grow the popularity of the sport generally. The term is most commonly used in reference to the North American major professional sports leagues but is applied to sports leagues in other countries with a closed franchise system of league membership. The term refers to the expansion of the sport into new areas. The addition of an expansion team sometimes results in the payment of an expansion fee to the league by the new team and an expansion draft to populate the new roster. Reasons for expansion
In North America, expansion often takes place in response to population growth and geographic shifts of population. Such demographic change results in financial opportunities to engage with the new market as consumers of sports demand local teams to support. Major League Baseball (MLB) was limited to 16 teams located north and east of St. Louis, Missouri for the first half of the 20th century. During that time, the United States population doubled and expanded to the south and west. Rival interests explored the possibility of forming a rival league in the untapped markets. To forestall that possibility, one of the measures that MLB took was to expand by four teams in 1961 and 1962. Over the past four decades, MLB expanded further, to its current 30-team membership. In the context of MLB, the term "expansion team" is also used to refer to any of the 14 teams enfranchised in the second half of the 20th century. Leagues that are new and/or financially struggling may also admit large numbers of expansion teams so that the existing franchises can pocket more revenue from expansion fees. Indoor American football leagues are notorious for doing so: the leagues can double the number of teams and have many new teams fail within a year or two. Major League Soccer, after spending most of its first decade of existence with relatively stable membership and struggling finances, adopted a policy of continuous expansion beginning in 2005, a policy that the league as of 2017 has no intention of stopping. When an expansion team begins play, it is generally stocked with less talented free agents, inexperienced players, and veterans nearing retirement. Additionally, prospective owners may face expensive fees to the league as well as high startup costs such as stadiums and facilities. The team is also at a disadvantage in that it has not been together as a team as long as its opponents and thus lacks the cohesiveness other teams have built over years. As a result, most expansion teams are known for their poor play during their first seasons. Expansion teams must also compete with any expansion rivals for available talent, a common problem since leagues often expand by two or four teams in one season. Expansion teams are not necessarily doomed to mediocrity, however, as most leagues have policies which promote parity, such as drafts and salary caps, which give some expansion teams the opportunity to win championships only a few years after their first season. In Major League Baseball (MLB) The Arizona Diamondbacks won the 2001 World Series in their fourth season, and the Florida Marlins won the 1997 World Series in their fifth season. In the NBA, The Milwaukee Bucks won the 1971 NBA Finals in their third year of existence, greatly helped by drafting Kareem Abdul-Jabbar in the 1969 draft and acquiring Oscar Robertson from the Cincinnati Royals before the 1970–71 season began. In the NHL, the Florida Panthers made the Stanley Cup Finals in their third season even though, like MLB, the league then had no salary cap; a cap was established in 2005. However, the Vegas Golden Knights quickly emerged as one of the NHL's best teams in its first season. Thanks to a generous expansion draft, the team defied all odds and advanced to the 2018 Stanley Cup Finals, and later winning the 2023 Stanley Cup Finals in just their sixth season. The National Football League (NFL), despite being considered the most generous in its revenue sharing and the strictest with its salary cap, has had far more difficulty bringing expansion teams up to par with their more established brethren. Of the six teams to have been added to the NFL since the AFL–NFL merger, the fastest turnaround between an inaugural season and the team's first Super Bowl victory was 27 seasons (the Tampa Bay Buccaneers, established in 1976, won Super Bowl XXXVII in the 2002 season); none of the four teams to hold expansion drafts since 1995 have ever won that contest, with only one, the Carolina Panthers (who reached the game in their 9th and 21st seasons of existence) playing in the game. In , the Panthers and Jacksonville Jaguars each made it to their respective conference championship games in their second season in the league. Expansion teams are usually considered as such in their first season and sometimes in their second season. A team that moves to another location and/or changes its name is not an expansion team. If it moves, it is known as a relocated team, and if the name changes, the team is known as a renamed team. In response to a negative attitude that some fans have towards relocated teams, there have recently been instances where relocating clubs change their identity completely; name, colors, and mascot; but because the roster is the same and the league does not expand as a result, they are not regarded as expansion teams. One exception is the Baltimore Ravens of the National Football League (NFL): when the Cleveland Browns moved to Baltimore, an agreement was reached for which the trademark and history of the pre-1996 Cleveland Browns remained in that city and was claimed by the post-1999 Browns when the league placed a new franchise there, even though the personnel and roster had moved to Baltimore to become the Ravens. Another exception is the New Orleans Pelicans, who were previously known as the New Orleans Hornets after relocating to New Orleans from Charlotte, N.C., in 2002. After the 2012 sale of the Hornets, new owner Tom Benson changed the name, colors, and mascot from Hornets to Pelicans. The Charlotte Hornets segment of the franchise's history was sold to the then-Charlotte Bobcats (themselves formerly considered a 2004 expansion team) and the 2002 New Orleans Hornets are now officially regarded as an expansion team. Cities and regions with large populations that lack a team are generally regarded to be the best candidates for new teams. In rugby league, the United Kingdom-based Rugby Football League's Super League has added teams from France and Wales to cover a great demographic spread. The operator of Super League, England's Rugby Football League, has also added teams to the lower levels of its league pyramid, specifically the Championship and League 1, from both France and Wales, and most recently Canada. In rugby union, the competition originally known as the Celtic League and now as Pro14, which began with sides only from the Celtic nations of Ireland, Scotland, and Wales, has added teams from Italy and more recently South Africa. The U.S.-based NFL has been laying groundwork for a potential franchise in the UK, with a target date some time in the early to mid-2020s. Expansion teams in North America

Major League Baseball (MLB)
The National League had an eight-team lineup established in 1900, mirrored by the eight charter franchises of the American League in 1901. This list enumerates franchises added since this "Classic Eight" era. 1961: Los Angeles Angels; Washington Senators (now Texas Rangers) 
1962: Houston Colt .45s (now Houston Astros); New York Mets
1969: Kansas City Royals; Montreal Expos (now Washington Nationals); San Diego Padres; Seattle Pilots (now Milwaukee Brewers)
1977: Seattle Mariners; Toronto Blue Jays
1993: Colorado Rockies; Florida Marlins (now Miami Marlins)
1998: Arizona Diamondbacks; Tampa Bay Devil Rays (now Tampa Bay Rays)

National Basketball Association (NBA)

Eight charter franchises of the NBA (founded in 1950 via merger of the BAA and NBL) are still active. 1961: Chicago Packers (later Chicago Zephyrs, then Baltimore Bullets, then Capital Bullets, then Washington Bullets, now Washington Wizards)
1966: Chicago Bulls
1967: San Diego Rockets (now Houston Rockets); Seattle SuperSonics (now Oklahoma City Thunder)
1968: Milwaukee Bucks; Phoenix Suns
1970: Cleveland Cavaliers; Buffalo Braves (later San Diego Clippers, now Los Angeles Clippers); Portland Trail Blazers
1974: New Orleans Jazz (now Utah Jazz)
1976: New York Nets (later New Jersey Nets, now Brooklyn Nets), Denver Nuggets, Indiana Pacers, and San Antonio Spurs join NBA after merger with American Basketball Association (ABA). 1980: Dallas Mavericks 
1988: Miami Heat; Charlotte Hornets 
1989: Minnesota Timberwolves; Orlando Magic
1995: Vancouver Grizzlies (now Memphis Grizzlies); Toronto Raptors
2002: New Orleans Hornets (now New Orleans Pelicans) – The Charlotte Hornets relocated to New Orleans in 2002 and in 2013 renamed themselves the New Orleans Pelicans. Subsequently, the original Charlotte Hornets' history was assumed by the revived Charlotte Hornets (previously Charlotte Bobcats; see below). Hence, the Pelicans are retrospectively considered to be an expansion team that began play in the 2002–03 season, while the Charlotte Hornets are considered to have suspended operations from 2002 until 2004. 2004: Charlotte Bobcats enter the league and hold an expansion draft. In 2014 the team was renamed the Charlotte Hornets (see above) and received possession of the history and records of the Charlotte Hornets prior to 2002. Hence, the Bobcats are retrospectively considered to be a revival of the previous Charlotte franchise, rather than an expansion team. American Basketball Association (ABA)
There’s only one expansion team in the whole history of the ABA. 1972: San Diego Conquistadors

National Football League (NFL)
Only extant teams are listed. Two charter franchises, the Chicago Cardinals (now Arizona Cardinals) and Decatur Staleys (now the Chicago Bears), are still active. 1921: Green Bay Packers, previously an independent, join the league. 1925: New York Giants (replaced another team of the same name that left the league after one season in 1921)
1930: Portsmouth Spartans (now Detroit Lions), previously of the Ohio League, join the NFL. 1932: Boston Braves (now Washington Commanders) – replaced the 1931 Cleveland Indians, who in turn replaced the Orange/Newark Tornadoes, a 1929 expansion team that left the league in 1931. 1933: Philadelphia Eagles — replaced the Frankford Yellow Jackets, a 1924 expansion team that folded in 1931; Pittsburgh Pirates (now Pittsburgh Steelers), previously the Rooneys of the Western Pennsylvania Senior Independent Football Conference, join the league. 1937: Cleveland Rams (now Los Angeles Rams) join, having previously played in the 1936 American Football League. 1950: Three teams joined the NFL after a partial merger with the rival All-America Football Conference (AAFC), two of which survive: Cleveland Browns and San Francisco 49ers
1953: Baltimore Colts (second) (now Indianapolis Colts); not to be confused with the AAFC Baltimore Colts, who were the third AAFC team to join the NFL but folded in 1950. They replaced the position held by several franchises, dating back to another charter franchise, the Dayton Triangles. 1960: Dallas Cowboys
1961: Minnesota Vikings
1966: Atlanta Falcons
1967: New Orleans Saints
1970: Boston Patriots (now New England Patriots), Buffalo Bills, Cincinnati Bengals, Denver Broncos, Houston Oilers (now Tennessee Titans), Kansas City Chiefs, Miami Dolphins, New York Jets, Oakland Raiders (now Las Vegas Raiders), and San Diego Chargers (now Los Angeles Chargers) join NFL after merger with the 1960 American Football League (AFL). 1976: Seattle Seahawks; Tampa Bay Buccaneers
1995: Carolina Panthers; Jacksonville Jaguars
1996: Baltimore Ravens — The Cleveland Browns effectively relocate to Baltimore and become the Ravens, though the legacy of the Browns stays in Cleveland for a future revival of the franchise (see below). Hence the Baltimore Ravens are officially considered an expansion team that began play in the 1996 season. 1999: The Cleveland Browns are revived, hold an expansion draft, and receive sole possession of the history and records of the Browns prior to 1996. The Browns are retrospectively considered to be a revival of the previous Cleveland Browns franchise, rather than an expansion team. 2002: Houston Texans

Baltimore Stallions (technically defunct) – The Stallions were the most successful team in the CFL's U.S. experiment, winning the Grey Cup in 1995. However, the impending relocation of the NFL's Cleveland Browns to Baltimore led the team to depart for Montreal, where it became the current version of the Montreal Alouettes.

Both had themselves been Super Rugby expansion teams; the Cheetahs entered in 2006 and the Kings in 2013. The Kings were liquidated prior to the 2020–21 season when a planned takeover bid collapsed in fraud; the Cheetahs left after that season. 2021:
