This was the eighth decade of the 20th century.

Oljekrisen 1973 och den följande lågkonjunkturen präglade decenniet. Vänsterrörelsen var stark i många länder och en annan rörelse som växte sig stark var miljörörelsen. Inom populärmusiken var disco populärt. Svenska ABBA och australiska The Bee Gees var två stora popgrupper. Punkrocken var en ny stil inom rockmusik, som protesterade mot samhället. En annan proteströrelse inom musik var progg. I Norden växte sig även dansbandskulturen stark.

Gli anni 1970 sono il decennio che comprende gli anni tra il 1970 e il 1979. In Italia, Anni di piombo.
