History of the Kansas City Chiefs

The following is a detailed history of the Kansas City Chiefs, a professional American football franchise that began play in 1960 as the Dallas Texans. The team was a charter member of the American Football League (AFL), and now is currently part of the National Football League (NFL).

The Texans won the AFL Championship in 1962, and the team relocated to Kansas City, Missouri the following year. In 1966, the Chiefs won their second AFL title and appeared in the inaugural AFL-NFL World Championship game. In 1969, the Chiefs won the final AFL title and went on to defeat the NFL's heavily favored Minnesota Vikings in Super Bowl IV. The Texans/Chiefs were the most victorious franchise in AFL history, compiling an 87–48–5 record from 1960 to 1969. However, their victory on January 11, 1970 remains the franchise's only Super Bowl title to date.

In 1959, Lamar Hunt, son of oil tycoon H. L. Hunt, began discussions with other businessmen in establishing an American football organization that would rival that of the National Football League. Since as early as 1958, Hunt had the interest of purchasing an NFL franchise and moving them to Dallas, Texas. His desire to secure a professional football franchise was further heightened after watching the historic 1958 NFL Championship Game between the Baltimore Colts and the New York Giants. The team that Hunt was most interested in buying was the Chicago Cardinals.
