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 (and the first AFL team to do so) and the first to appear in the championship game in two different decades.
