The American Football League (AFL) champion Kansas City Chiefs defeated the National Football League (NFL) champion Minnesota Vikings by the score of 23--7 . This victory by the AFL squared the Super Bowl series with the NFL at two games apiece . The two leagues merged into one after the season . </P> <P> Despite the AFL's New York Jets winning the previous season's Super Bowl, many sports writers and fans thought it was a fluke and continued to believe that the NFL was still superior to the AFL, and thus fully expected the Vikings to defeat the Chiefs; the Vikings entered the Super Bowl as 12.5 to 13 - point favorites . Minnesota posted a 12--2 record during the 1969 NFL season before defeating the Cleveland Browns, 27--7, in the 1969 NFL Championship Game . The Chiefs, who previously appeared in the first Super Bowl, finished the 1969 AFL season at 11--3, and defeated the Oakland Raiders, 17--7, in the 1969 AFL Championship Game . </P>
