The Minnesota Vikings made their NFL debut in 1961, defeating the Chicago Bears, 37-13.
The Vikings won the last NFL Championship (1969) before the NFL-AFL merger, defeating the Cleveland Browns, 27-7.
When Bud Grant took over the head coaching job in 1967, the Vikings became one of the juggernauts in the league. During his tenure from 1967-83, the Vikings won 11 division titles, and three NFC titles in 1973, 1974, and 1976.
The Vikings appeared in four Super Bowls in the 1970s.
From 2006-08, the Vikings had the number-one ranked run defense in the league – the first team since the 1970 AFL-NFL merger that a team held it for three consecutive years.
