The Ibrox disaster occurred on 2 January 1971 when large-scale crushing on a stairway exit at the culmination of an Old Firm game claimed 66 lives.
An enquiry concluded that the crush was likely to have happened 10 minutes after the final whistle and to have been triggered by someone falling on the stairs.
A benefit match to raise funds for the victims' families took place after the disaster, a joint Rangers and Celtic team playing a Scotland XI at Hampden, watched by 81,405 fans.

In 1972, Rangers emerged from the tragedy of the previous year to finally achieve success on the European stage.
A Colin Stein goal and a Willie Johnston double helped secure a 3–2 victory over Dynamo Moscow at the Nou Camp, Barcelona, to lift the European Cup Winners' Cup.
Captain John Greig received the trophy in a small room within the Nou Camp following pitch invasions by Rangers fans reacting to the heavy handed tactics of the Spanish police, the majority of whom had been brought in from outwith Catalonia.
Rangers were banned from Europe for two years for the behaviour of their fans, later reduced on appeal to one year.

The following season saw the club compete in the first ever European Super Cup, although the European ban saw it officially recognised as Rangers centenary anniversary match.
The side played the European Cup holders Ajax, who had first proposed the idea, in January 1973.
The Dutch side proved too strong and recorded a 6–3 aggregate win, with Rangers losing 1–3 at Ibrox and 3–2 in Amsterdam.

Emerging from the shadows of Jock Stein's Celtic side, Rangers regained ascendancy with notable domestic success under the stewardship of manager Jock Wallace.
In his first season in charge – the club's centenary – Rangers won the Scottish Cup at Hampden in front of 122,714 supporters.
In 1974–75, Wallace led Rangers to their first League championship triumph in 11 years, before winning the treble the following season, repeating the historic feat in 1977–78.

John Greig served as manager for five years but was unable to achieve the success as a manager that he had as a player.
Unable to win the league during his reign, he was replaced by Wallace returning in 1983.
Wallace was unable to repeat the success of his first period in charge with a win ratio of less than 50%, and was himself replaced by Graeme Souness in 1986.
