Grass Curtain was a quarterly journal of Southern Sudanese politics and current events published by the Southern Sudan Association in London between 1970 and 1972. Enoch Mading de Garang was the journal's co-founder and editor-in-chief. The "Grass Curtain" was closely linked to the Southern Sudan Liberation Movement (SSLM), the political arm of Anya-Nya, a collection of Southern Sudanese separatist movements formed during the First Sudanese Civil War. The journal was published in large part to generate wider support for the South Sudanese cause.
