The Chiefs won Super Bowl LIV, defeating the 49ers 31-20 much to the delight of their fan base.
The Chiefs last played in the big game in 1970 at Super Bowl IV, which was the final AFL-NFL World Championship Game. They took down the Minnesota Vikings 23–7.
Kansas City reached Super Bowl I after winning the AFL Championship in 1966, but lost to the NFL's Green Bay Packers.
In the pre-Super Bowl era, the franchise—then the Dallas Texans—won the AFL by beating the Houston Oilers in overtime in 1962.
The Chiefs ranked behind only the Detroit Lions and the New York Jets for the teams with the longest Super Bowl droughts before clinching their spot to this year's big game. The Lions have not returned to the championship game in 62 seasons, while the Jets haven't appeared in a Super Bowl in 51 years.
