<Li> Arrowhead Stadium (1972--present) </Li> <P> 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 1960 as the Dallas Texans by businessman Lamar Hunt and was a charter member of the American Football League (AFL) (they are not associated with an earlier Dallas Texans NFL team that only played for one season in 1952). In 1963, the team relocated to Kansas City and assumed their current name . The Chiefs joined the NFL as a result of the merger in 1970 . The team is valued at over $2 billion . </P> <P> The Chiefs have won three AFL championships, in 1962, 1966, and 1969 and became 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 . The team's victory on January 11, 1970, remains the club's last championship game victory and appearance to date, and occurred in the final such competition prior to the leagues' merger coming into full effect . The Chiefs were also the second team, after the Green Bay Packers, to appear in more than one Super Bowl (the first AFL team to do so) and the first to appear in the championship game in two different decades . </P> <P> 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 . </P>
