Popular Socialist Youth of Denmark
Socialistisk Folkepartis Ungdom is the youth wing of the Green Left of Denmark, founded in 1969.
In 1995, the leftist section of the SFU broke away and formed Independent Young Socialists, which evolved into the Socialist Youth Front.
In 2021 SFU consisted of 1,272 members.
In their manifesto they describe themselves as using certain "Marxist tools" in their analysis of the world.
