Timeline
This timeline of the National Football League (NFL) tracks the history of each of the league's 32 current franchises from the early days of the league, through its merger with the American Football League (AFL). The history of franchises that began as independent teams, or as members of the Ohio League, New York Pro Football League, and other defunct leagues are shown as well.
The American Professional Football Association is formed September 17, 1920, at Canton, Ohio, with Jim Thorpe elected president. [1] The fourteen teams were mainly drawn from the Ohio League, Chicago Circuit, New York Pro Football League and other teams from the lower midwest. A $100 membership fee was charged. The Chicago Tigers folded after the season. [2]

The American Professional Football Association is reorganized at Akron, Ohio on April 30, 1921, with Joe F. Carr elected as new league president. [1] With the low entry barrier of a $100 membership fee, the number of teams balloons to 21. [1] Four of these franchises would last only one season, with Tonawanda Kardex only making it through a single game. Three other franchises folded mid-season.

Prior to the season, the league decided to eliminate the financially weaker teams. As a result, the league dropped from 22 to 12 teams, and a majority of the remaining teams were centered around the East Coast instead of the Midwest, where the NFL had started. The New York Yankees were added from the American Football League and the Cleveland Bulldogs returned.

[1] Despite the fee increase, three new teams were added to the league — the Cincinnati Reds, Philadelphia Eagles, and Pittsburgh Pirates. The league split into Eastern and Western Divisions with the winner of each division playing in the NFL Championship Game. The 1933 season would be the first in which no NFL team folds or suspends operations. The team roster limit remained at 20 players.[ citation needed ]

As America became more deeply embroiled in World War II, the Cleveland Rams suspend operations for the 1943 season due to a major loss in players. The Philadelphia Eagles and Pittsburgh Steelers were able to work around the player shortage by merging to form the "Phil-Pitt Steagles."
Size of the active roster reduced from 33 to 28 players per team. [6] Intent of this reduction was to appease the Office of Defense Transportation by reducing the impact of travel by road teams. [7] Additionally, teams primarily used day coaches rather than sleeper cars, a more efficient albeit less comfortable mode of travel. [7] This continued through the 1944 season.

The American Football Conference (AFC) is one of the two conferences of the National Football League (NFL), the highest professional level of American football in the United States. The AFC and its counterpart, the National Football Conference (NFC), each contain 16 teams with 4 divisions. Both conferences were created as part of the 1970 merger between the National Football League, and the American Football League (AFL). All ten of the AFL teams, and three NFL teams, became members of the new AFC, with the remaining thirteen NFL teams forming the NFC. A series of league expansions and division realignments have occurred since the merger, thus making the current total of 16 teams in each conference. The current AFC champions are the Kansas City Chiefs, who defeated the Baltimore Ravens in the 2023 season's AFC Championship Game for their fourth conference championship and went on to win Super Bowl LVIII against the San Francisco 49ers.
The All-America Football Conference (AAFC) was a major professional American football league that challenged the established National Football League (NFL) from 1946 to 1949. One of the NFL's most formidable challengers, the AAFC attracted many of the nation's best players, and introduced many lasting innovations to the game. However, the AAFC was ultimately unable to sustain itself in competition with the NFL. After it folded, three of its teams were admitted to the NFL: the San Francisco 49ers, the Cleveland Browns and the original Baltimore Colts.
The National Football Conference (NFC) is one of the two conferences of the National Football League (NFL), the highest level of professional American football in the United States. The NFC and its counterpart, the American Football Conference (AFC), each have 16 teams organized into four divisions. Both conferences were created as part of the 1970 NFL merger with the rival American Football League (AFL). All ten of the former AFL teams and three NFL teams formed the AFC while the remaining thirteen NFL clubs formed the NFC. A series of league expansions and division realignments have occurred since the merger, thus making a total of 16 clubs in each conference.
The Brooklyn Dodgers were an American football team that played in the National Football League from 1930 to 1943, and in 1944 as the Brooklyn Tigers. The team played its home games at Ebbets Field of the baseball National League's team, the Brooklyn Dodgers. In 1945, because of financial difficulties and the increasing scarcity of major league–level players because of the war-time defense requirements at the height of World War II, the team was merged with the Boston Yanks and were known as the Yanks for that season.
Below is a list of professional football Championship Games in the United States, involving:
The AFL–NFL merger was the merger of the two major professional American football leagues in the United States at the time: the National Football League (NFL) and the American Football League (AFL). It paved the way for the combined league, which retained the "National Football League" name and logo, to become the most popular sports league in the United States. The merger was announced on the evening of June 8, 1966. Under the merger agreement, the leagues maintained separate regular-season schedules for the next four seasons—from 1966 through 1969 with a final championship game which would become known as the Super Bowl—and then officially merged before the 1970 season to form one league with two conferences.
Throughout its history, the National Football League (NFL) and other rival American football leagues have used several different formats to determine their league champions, including a period of inter-league matchups to determine a true national champion.
The AFC Championship Game is the annual championship game of the American Football Conference (AFC) and one of the two semifinal playoff games of the National Football League (NFL), the largest professional American football league in the world. The game is played on the last Sunday in January by the two remaining playoff teams, following the AFC postseason's first two rounds. The AFC champion then advances to face the winner of the NFC Championship Game in the Super Bowl.
The National Football Conference – Western Division or NFC West is one of the four divisions of the National Football Conference (NFC) in the National Football League (NFL). It currently has four members: the Arizona Cardinals, the Los Angeles Rams, the San Francisco 49ers, and the Seattle Seahawks.
The American Football Conference – Eastern Division or AFC East is one of the four divisions of the American Football Conference (AFC) in the National Football League (NFL). There are currently four teams that reside in the division: the Buffalo Bills, the Miami Dolphins, the New England Patriots, and the New York Jets. All four members of the AFC East were previously members of the Eastern Division of the American Football League (AFL).
The American Football Conference – Northern Division or AFC North is one of the four divisions of the American Football Conference (AFC) in the National Football League (NFL). The division was created after the restructuring of the 2002 NFL season when the league realigned divisions after expanding to 32 teams. The division consists of the Baltimore Ravens, Cincinnati Bengals, Cleveland Browns, and Pittsburgh Steelers. This is the only division in the NFL in which no member team has hosted a Super Bowl in their stadiums. The division, however, has won eight Super Bowl titles in total.
The American Football Conference – Western Division or AFC West is one of the four divisions of the American Football Conference (AFC) in the National Football League (NFL). The division comprises the Denver Broncos, Kansas City Chiefs, Las Vegas Raiders, and Los Angeles Chargers.
The 1970 NFL season was the 51st regular season of the National Football League, and the first after the consummation of the AFL–NFL merger. The merged league realigned into two conferences: all ten of the American Football League (AFL) teams joined the Baltimore Colts, Cleveland Browns, and Pittsburgh Steelers to form the American Football Conference (AFC); the other thirteen NFL clubs formed the National Football Conference (NFC).
The 1949 NFL season was the 30th regular season of the National Football League. Prior to the season, Boston Yanks owner Ted Collins asked the league to fold his team due to financial woes and give him a new one in New York City. This new team would be called the New York Bulldogs. The franchise, which has never missed a season in some form, carried on the legacy of the final Ohio League member Dayton Triangles, and the players and assets of the Boston Yanks moved to New York but did not fold. As a result of the move, professional football would not return to Boston until the Boston Patriots of the 4th American Football League began play in 1960.
Throughout the years, a number of teams in the National Football League (NFL) have either moved or merged.
The American Football League (AFL) was a professional American football league that operated in 1936 and 1937. The AFL operated in direct competition with the more established National Football League (NFL) throughout its existence. While the American media generally ignored its operation, this second AFL was the first "home" of the Cleveland Rams, which joined the National Football League after one year in the AFL.
The National Football League (NFL) was founded in 1920 as the American Professional Football Association (APFA) with ten teams from four states, all of whom existed in some form as participants of regional leagues in their respective territories. The league took on its current name in 1922. The NFL was the first professional football league to successfully establish a nationwide presence, after several decades of failed attempts. Only two founding members are still in the league, the Decatur Staleys and the Chicago Cardinals is the oldest NFL franchise.
The Baltimore Colts were a professional American football team that played in Baltimore from 1953 to 1983, when owner Robert Irsay moved the franchise to Indianapolis. The team was named for Baltimore's history of horse breeding and racing. It was the second incarnation of the Baltimore Colts, the first having played for three years in the All-America Football Conference and one in the National Football League (NFL). This Baltimore Colts played their home games at Memorial Stadium.
