Document 2: Kansas City Chiefs: 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.

Document 3: History of the National Football League championship: From 1966 -- 1969 prior to the merger in 1970, the NFL and the AFL agreed to hold an ultimate championship game, first called the AFL - NFL World Championship Game and later renamed the Super Bowl after 1968. Following the merger in 1970, the Super Bowl name continued as the game to determine the NFL champion. The most important factor of the merger was that all ten AFL teams joined the NFL in 1970 and every AFL championship game and record is included in NFL record books. The old NFL Championship Game became the NFC Championship Game, while the old AFL Championship Game became the AFC Championship Game. The NFL lists the old AFL / NFL championship games with ``new ''AFC / NFC championship games in its record books. The Green Bay Packers have won the most championships with 13 total (9 NFL championships pre-merger, four (4) Super Bowl championships). The Packers are also the only team to win three consecutive championships, having done so twice (1929 -- 1931, 1965 -- 1967). The Chicago Bears have won the second most overall championships with nine (9) (eight NFL championships, one Super Bowl championship).
