The Chiefs have won three AFL championships, in 1962, 1966, and 1969. They 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. Despite post-season success early in the franchise's history, winning five of their first six postseason games, the team has struggled to find success in the playoffs since. As of the conclusion of the 2018–19 playoffs, they have lost 12 of their last 14 playoff games, including eight straight, at the time the longest playoff losing streak in NFL history. The playoff losing streak stretched from the 1993-94 AFC Championship game to the 2013-14 Divisional Round. The only playoffs wins over the last 14 playoff games were a 30–0 win over the Texans in the 2015–16 playoffs and a 31–13 over the Colts in the 2018–19 playoffs.
