In 1959, Lamar Hunt began discussions with other businessmen to establish a professional football league that would rival the National Football League. he 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.

The franchise became one of the strongest teams in the now thriving American Football League, with the most playoff appearances for an AFL team (tied with the Oakland Raiders), and the most AFL Championships. The team's dominance helped Lamar Hunt become a central figure in negotiations with NFL Commissioner Pete Rozelle to agree on an AFL–NFL merger. While the first few games were designated the "AFL–NFL World Championship Game," the Super Bowl name became its officially licensed title in years to come.

In 1972, the Chiefs moved into the newly constructed Arrowhead Stadium at the Truman Sports Complex outside of Downtown Kansas City. The team's first game at Arrowhead was against the St. Louis Cardinals, a game which the Chiefs won 24–14. John Mackovic took over head coaching duties for the 1983 season after Marv Levy was fired. Over the next four seasons, Mackovic coached the Chiefs to a 30–34 record, but took the team to its first post-season appearance in 15 years in the 1986 NFL playoffs. Following the team's loss to the New York Jets in the playoffs, Mackovic was fired. Frank Gansz served as head coach for the next two seasons, but won only eight of 31 games.

In 2003, Kansas City began the season with nine consecutive victories, a franchise record. They finished the season with a 13–3 record and the team's offense led the NFL in several categories. Running back Priest Holmes surpassed Marshall Faulk's single-season touchdown record by scoring his 27th rushing touchdown against the Chicago Bears in the team's regular season finale.
