The Kansas City Chiefs are a professional American football team based in Kansas City, Missouri. The Chiefs compete in the National Football League (NFL) as a member club of the league's American Football Conference (AFC) West division.

The team was founded in 1959 as the Dallas Texans by businessman Lamar Hunt, and was a charter member of the American Football League (AFL). In spring 1963, the team relocated to Kansas City, and assumed its current name. The Chiefs joined the NFL as a result of the merger in , and the team is valued at over $3.7 billion. Following Hunt's death in 2006, his wife, Norma, and children became legal owners of the team. After Norma's death in 2023, the Hunt children inherited her stake in the franchise. Clark Hunt, one of the Hunt's children, has served as chairman and CEO since 2006 and is the ultimate authority over personnel decisions. He is also the team representative at league owner meetings.

The Chiefs won three AFL championships, in 1962, 1966, and 1969, and were the second AFL team (after the New York Jets) to defeat an NFL team in an AFL–NFL World Championship Game, when they defeated the Minnesota Vikings in Super Bowl IV. That victory on January 11, 1970, was the final game before the leagues' merger went into full effect. The Chiefs were also the second team, after the Green Bay Packers (whom they played in Super Bowl I), to appear in more than one Super Bowl (and the first AFL team to do so) as well as the first to appear in the championship game in two different decades. Despite post-season success early in the franchise's history, winning five of their first six postseason games, the team struggled to find success in the playoffs for decades, including losing ten of eleven playoff games from 1993 to 2017, which included an eight-game losing streak. Since then, the Chiefs have risen to dynastic performance under head coach Andy Reid, quarterback Patrick Mahomes, and tight end Travis Kelce, appearing in three Super Bowls since 2019 and winning two, LIV and LVII.

Franchise history

American Football League

In 1959, Lamar Hunt began discussions with other businessmen to establish a professional football league that would rival the National Football League. Hunt's desire to secure a football team was heightened after watching the 1958 NFL Championship Game between the New York Giants and Baltimore Colts. After unsuccessful attempts to purchase and relocate the NFL's Chicago Cardinals to his hometown of Dallas, Texas, Hunt went to the NFL and asked to create an expansion franchise in Dallas. The NFL turned him down, so Hunt then established the American Football League and started his own team, the Dallas Texans, to begin play in 1960.

Hunt hired a little-known assistant coach from the University of Miami football team, Hank Stram, to be the team's head coach after the job offer was declined by Bud Wilkinson and Tom Landry. After Stram was hired, Don Klosterman was hired as head scout, and was credited by many for bringing a wealth of talent to the Texans after luring it away from the NFL, often hiding players and using creative means to land them.

The Texans shared the Cotton Bowl with the NFL's Dallas Cowboys for three seasons. The Texans were to have exclusive access to the stadium until the NFL put an expansion team, the Dallas Cowboys, there. While the team averaged a league-best 24,500 at the Cotton Bowl, the Texans gained less attention due to the AFL's relatively lower profile compared to the NFL's. In the franchise's first two seasons, the team managed only an 8–6 and 6–8 record, respectively.

In their third season, the Texans tallied an 11–3 record and a berth in the team's first American Football League Championship Game, against the Houston Oilers. The game was broadcast nationally on ABC and the Texans defeated the Oilers 20–17 in double overtime. The game lasted 77 minutes and 54 seconds, which, at the time, was the longest game in the history of professional American Football. It is still the longest championship game in American Football League history.

It turned out to be the last game the team would play as the Dallas Texans. Despite competing against a Cowboys team that managed only a 9–28–3 record in their first three seasons, Hunt decided that the Dallas–Fort Worth media market could not sustain two professional football franchises. He considered moving the Texans to either Atlanta or Miami for the 1963 season. He was ultimately swayed by an offer from Kansas City Mayor Harold Roe Bartle. Bartle promised to triple the franchise's season ticket sales and expand the seating capacity of Municipal Stadium to accommodate the team.
