The Kansas City Chiefs are a professional American football team based in Kansas City, Missouri. They are currently members of the Western Division of the American Football Conference (AFC) in the National Football League (NFL). The Chiefs conduct summer training camp at University of Wisconsin-River Falls. Originally called the Dallas Texans, the club was founded by Lamar Hunt in 1960 as a charter member of the American Football League. The team moved to Kansas City and became the Chiefs in 1963 after then-Kansas City mayor H. Roe Bartle guaranteed to the team that they would have increased ticket sales. The Chiefs then joined the NFL as part of the AFL-NFL Merger. The Chiefs hold the distinction of being the second AFL team (after the New York Jets) to defeat an NFL club in an AFL-NFL World Championship Game when they defeated the Minnesota Vikings in Super Bowl IV.
