4 (Степлаг (Степной лагерь), Особлаг (Особый лагерь) № 4) was an MVD special camp for political prisoners within the Gulag system of the Soviet Union.
It was established on February 28, 1948, on the base of the Spasozavodsky (Спасозаводский) POW camp near Karaganda, Kazakhstan.
In 1956, Steplag was disestablished, and its camps were transferred to the administration of the Kazakh SSR.
[2] Initially it was planned for 10,000 inmates,[1] but it was expanded with more subcamps and at its height it held about 28,000 in 1950.
