The team started playing in 1959 as the Dallas Texans by businessman Lamar Hunt and was a charter member of the American Football League (AFL).[12] In 1963, the team moved to Kansas City,[13][14] and kept its current name.[15][16] The Chiefs joined the NFL as a result of the 1970 AFL–NFL merger; entering the 2024 season, the team is valued at over US$4.85 billion. After 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 Hunts' 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 were victorious and won three AFL championships, in 1962, 1966, and 1969,[17][18] and were the second AFL team (after the New York Jets) to defeat an NFL team in a Super Bowl when they defeated the Minnesota Vikings in Super Bowl IV, which was the final game before the league 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) and the first to appear in the championship game in two different decades. Despite this post-season success, the team failed to find success in the playoffs for decades, including losing ten of eleven playoff games from 1993 to 2018, which included an eight-game losing streak.

At one of the initial organizational meetings of the American Football League in late '59 – before the teams even had any players or coaches – the AFL owners choose their team colors. Lamar Hunt desires Columbia Blue and Orange for his Dallas Texans franchise. But before Hunt or any other owner can make a selection, Houston's Bud Adams claims Columbia Blue for his Oilers franchise. Hunt reverts to Red and Gold for the Texans, which remains the primary color scheme for the Chiefs to this day.
