Union of Working Youth (Hungarian: Dolgozó Ifjúság Szövetsége, DISZ) was a mass youth organization in Hungary. All Hungarian youth between 14 and 26 years were allowed to become members. As of 1956, DISZ had 14 000 local organizations and a total membership of around 800 000. During its existence, DISZ oversaw the pioneer movement in Hungary.[1]
DISZ published Szabad ifjúság weekly from October 1950 to July 1951, and daily from August 1951 to October 1956.[2]
Within DISZ oppositional tendencies emerged. DISZ set up the 'Petőfi Circle', which became a centre of dissidence against the Hungarian government.[3]
After the dissolution of DISZ, the Hungarian Young Communist League (KISZ) was set up. Unlike DISZ, KISZ was a cadre organization.[4]
